Introduction - Tiny Home and ADUs?

As housing costs rise and cities search for new ways to increase the supply of housing, many are turning to housing concepts such as tiny homes and ADUs (Accessory Dwelling Units) to meet this demand. Indeed, tiny homes and ADUs are no longer fringe experiments—they’re one of the most practical, creative, and financially savvy responses to rising housing costs, zoning constraints, and the desire to build something deeply personal. Whether you’re adding an ADU as a passive income device, downsizing into a tiny home tucked into a redwood forest, or exploring ideas that would never survive the complexity of a full-scale house, these smaller dwellings offer outsized benefits. Lower construction costs, faster build timelines, and fewer regulatory hurdles make tiny homes and ADUs uniquely accessible while still delivering flexibility, sustainability, and long-term value for homeowners and designers alike. 

Just as importantly, the rapid development AI-powered design is starting to offer tiny home and ADU designers opens up a rare opportunity for architectural expression at a human scale and offers a better way for owners and architects to communicate design goals. Indeed, these stakeholders can use AI to rapidly explore bold ideas early in the design process within real-world size and complexity limits—recreating long-forgotten styles like Art Nouveau in a redwood forest backdrop, or designing a small but grand feeling backyard rental inspired by the Frank Lloyd Wright’s Ennis House. By leveraging AI-generated architectural concepts, tiny home builders can unlock creativity faster, iterate visually, and pursue exciting one-of-a-kind projects that feel intentional, expressive, and unmistakably personal—all without the friction of traditional early-stage design workflows.

ADU and Tinyhome Concept Gallery

With that context, let’s look at a concept gallery showing how large architectural ideas can be scaled down into thoughtfully designed ADUs and tiny homes.

Backyard Accessory Dwelling Units (ADUs)

Many single family home neighborhoods severely limit the size of a house relative to its lot size, frequently leaving far more yard space than some people need. However, recent zoning law changes in many places, such as California, are allowing the construction of small backyard cottages (ADU’s) that homeowners can use to add density to their backyard, be that as a rental or frequently a way for elders to downsize and age in place close to family.

Understanding how this can fit into a lot is a case by case question, but let’s take a look at a few examples of what that could look like for the more ambitious ADU designers among us.

Remixing ADU Designs with AI

ADU design doesn’t have to default to something bland, boxy, or forgettable in order to be affordable. With thoughtful use of color, ornament, material changes, and a few strategic articulations, even a simple structure can be transformed into something expressive and memorable. The underlying box may stay the same, but the architectural character does not have to. This is where AI becomes especially useful as a creative amplification tool rather than a replacement for good design judgment.

One of the most effective ways to leverage AI in ADU design is through remixing, retexturing, and style transfer workflows. By feeding image references or existing ADU massing studies into AI image generators, designers and homeowners can rapidly explore variations in façade treatment, material palettes, window proportions, and architectural styles without committing to costly redraws. This makes AI a powerful early-stage tool for testing ideas, communicating design intent, and pushing beyond the default “developer-grade” ADU aesthetic. 

The slide deck below shows and example of what that AI-assisted design process might look like (also see our posts on the Best AI Image Generators of 2026, AI rendering, and of AI 2D to 3D tools for additional examples).

Tiny Home and ADU Interior Design

Despite all the focus on the facade in this article, the purpose of the facade is to create and protect an interior space. Thus we need to give equal consideration to the interiors as well. Though image generators aren’t the best at coherent space planning (keep an eye out for nonsensical furnishing decisions), they can provide a great jumping off point to envision and iterate on an interior design aesthetic that fits with your ADU design.

ADUs - Reimagining Architecture on a Smaller Scale

Ever seen a large magnificent house or famous, grandiose feat of monumental architecture and wished you could have just a slice of it at home? Well with image references, you can easily work the design elements of much larger projects into a much smaller form factor. This could be a great tool for architects looking to experiment with details on a smaller scale before applying them on larger projects, or just for architecture enthusiasts who want a quaint little dream home that takes inspiration from the greats.

Wilderness Tiny Homes

And lastly, while what we have looked at so far focuses mainly on ADU design for infill to make suburban neighborhoods denser, sometimes you just want to get away and build an off-grid tiny home out in the forest where you can realized your wildest architectural dreams. While these wilderness tiny homes aren’t traditional ADUs, the same design principles—efficiency, expression, and AI-driven iteration—apply directly to backyard ADU design.

The question then becomes: If you had your ideal tiny house in the woods, what would you build?

Head-to-Head Comparison

Introduction

If you’re confused about which AI image platforms you should learn to integrate AI into your workflow, you’re not alone. A plethora of AI platforms are on the market in 2026 and it can be hard to determine which is right for your practice. Well fortunately, we at Pixels to Plans did the legwork for you and analyzed 14 of the best AI image generators for architecture to see how they stack up. This article presents a comprehensive study of each platform, the tools they offer, and how to leverage the strengths of each one to develop an AI design workflow for your projects.

The Contenders

To start off, let’s look at the competition:

1. Midjourney – The original gold standard of high-quality image generation remains a fierce competitor in 2026. This is a high-creativity platform known for its coherency and aesthetics. Subscriptions start at $10/month as of January 2026.
2. Google Nano Banana – One of the most powerful and coherent free AI image generators on the market, you can use Google Nano Banana for free through Google’s Gemini LLM platform.
3. Recraft – Formerly known as Project Red Panda, this UK-based AI image platform burst onto the scene with its pleasant user interface, vibrant generations, and good prompt comprehension. It uses a canvas style interface to help organize your thoughts and creations, which can help guide a design process. It offers a decent number of free daily credits to explore with.
4. GPT4o – ChatGPT’s image generator gained notoriety recently when it demonstrated how LLMs could interpret prompts for more careful control of the image generation process (and notoriety it’s blatant blatant use of Studio Ghibli style). While it still has its tell-tale yellow tinge, this platform is an accessible way for users already familiar with ChatGPT to craft their images through natural language rather than through strings of keywords and commas like many other generators.
5. Dall-E 3 (Bing Image Creator) – This is the model used in the Bing Image Creator platform and offers fairly good artistic and text effects. It is developed by OpenAI, making it part of the ChatGPT/Microsoft/Bing ecosystem, and can be accessed directly by GPT 4.
6. Leonardo AI – (Flux Dev Model) – Leonardo AI is an image and video model aggregator platform that allows users to experiment with many different models from . While it offers many options and controls for users, its free credit system is limited and it can have a daunting user interface. Though we assessed several of the model options on Leonardo, in this article we present results from the widely popular Flux Dev model, which is readily available on that platform due to its higher quality compared to Leonardo’s default models
7. Vizcom – This is largely an automotive and product-design-focused platform for sketch-to-render and creative fusion tools. It prioritizes giving designers more authorship compared to more randomized image generators and offers a high level of control over developing existing design concepts further. It can produce good results with architecture, but is only with the right workflow.
8. Imagen– Imagen is another Google product preceding the introduction of Nano Banana. It has its own aesthetic and excellent prompt comprehension that may be worth considering when other models aren’t cutting it. It can be used on the Google Whisk platform.
9. Canva– Graphic design web app Canva has recently forayed into the world of generative AI and produces some relatively promising and grounded results. It’s definitely worth a look next time you are putting together an architecture board in Canva or when you want a look that’s just a bit different from the more AI-art focused generators.
10. Adobe Firefly – While free generations are limited to an extremely small free trial, Adobe’s AI platform Firefly aggregates multiple models and uses Adobe licensed stock images in its training, circumventing some of the more dubious training data sources of other models. This model is a good choice for those already working in the Adobe ecosystem.
11. PromeAI – This is another freemium platform that put sketch-to-render tools on the map. It offers a broad array of tools and has an extensive list of present styles specifically for architecture. It allots credits on a monthly basis though unlike others that allot them daily so use them wisely
12. Ideogram – Ideogram is often cited as one of the higher quality image generators and tends to do very well at generating scenes with realism, diverse compositions, dramatic immersive lighting, and coherent layouts for things like interiors. However, its free plan is extremely limited and typically requires a costly subscription to get any meaningful amoutn of generations out of it.
13. Krea – Krea’s claim to fame is real time generation that lets you sketch or collage together a base image and reimagines it in real time with each brushstroke. This option is great for quickly iterating on an idea when you’re an illustrator that wants to rapidly visualize based on a work in progress sketch, but can be clunky and low quality for most other applications. However, for architects their image to 3D tool is really where this platform shines.
14. Reve – This very minimalist image editor and generator may not be known as your typical tool for architectural projects, but it’s focus more on editing and product design brings some interesting perspectives and compositions to the images it creates that you won’t typically get with other generators. Consider this when you want results that look a bit more outside the box and unexpected.

Prompt Benchmarks – 2026

For our 2026 roundup, we will be comparing these platforms using five prompt benchmarks (carefully selected prompts meant to test AI models). The concept of benchmarking is rooted in computer science and LLMs, but for AI art and architecture they are best exemplified and explained by Andrei Kovalev’s Midlibrary, a non-profit educational initiative that catalogues and blogs about about various Midjourney styles.

For this study I developed the following benchmarks:

1. Modern and Earthy
   • Prompt: Organic modern home, indoor outdoor flow, rammed earth walls, biophilic courtyard oasis.
2. Miniatures and Mixed Styles
   • Prompt: Close up worm’s-eye view low-angle shot wide angle photo of a physical miniature model of usonian, art nouveau inspired courtyard homes, camera in an inviting serene modeled alleyway, camera low to the table looking up at the model as if it were miniature, moss lined mini plazas, laser-cut wood and intricate cardboard relief ornamentation resembling terra cotta in miniature, central piazza visible beyond
3. Cozy and Colorful Interiors
   • Prompt: Award winning photos of a stylish interior design for a small accessory dwelling unit tinyhome, Expressive, biophilic, hygge, space with a view out the large window to the back yard, with vivid and tasteful use of color, verticality, built-in storage, loft bed with a guardrail, high ceiling, and efficient use of space
4. Bold Maximalism
   • Prompt: Instagram photo of a kitschy Googie inspired coffee kiosk with a sign that reads “coffee” by the freeway, bold swooping cantilevers, neon boomerang signage, pastel and chrome surfaces, alien space age aesthetic with reflections and sunset sky, lush landscaping, ultra sharp
5. Solarpunk Cityscape
   • Prompt: solarpunk cityscape photo, lots of buildings, panoramic, lush plants, dawn mist, civil twilight, intricate detail, hyperrealistic

I selected these prompts to showcase how each platform deals with different concepts. These five prompts assess how the platform balances intricate modernist practicality with the texture and physical constraings of a material like rammed earth, how well it depict physical miniature models, what it sees as tasteful use of color and whether their interior layouts make sense, how interesting a form it can imagine for a maximalist coffee kiosk, and its views on solarpunk futurism along with its handling of panoramic views.

Also, for examples of other simpler benchmarks and to see how AI has progressed in the last few years, refer to our previous post on the Best AI Image Generators for Architecture.

Benchmark Results

The graphic below, and the enlarged version you can explore on Canva, show how each of the fourteen platforms handle these benchmarks.

You can zoom in on Canva to better understand he nuances of each output.

Benchmark Takeaways

How well do you think each platform adhered to the prompt? Were there any results that surprised you? While I’m sure you can spot some trends yourself, some of my key takeaways from the study include:

• Some models (Dall-E-3, Firefly, Flux, and the unmistakable GPT4o) have a distinctly more “AI generated” look than other models. The most consistently realistic looking ones included Nano Banana, Imagen, Krea, and Ideogram.
• Most struggled to understand the concept of rammed earth and how it can be applied. Only Nano Banana, GPT4o, and recraft really got the look right, and even then it showed rammed earth hovering overhead showing a lack of realism.
• Some struggled with depicting a worms eye view of the miniature, but all did relatively well at producing a tilt shift effect and papery materiality.
• When it comes to blending usonian with art nouveau, Reve, PromeAI, Nano Banana, Imagen, Ideogram, and Firefly leaned towards the organic chaos approach, while others like Midjourney and Recraft captured a more usonian modern aesthetic.
• For tasteful color, many tended towards teal, navy, and wood tones, while others took on more minimal white palettes. Nano banana, midrjourney, and GPT4o were the most bold in their color choices. However in many cases, the layout was less than coherent with several results lacking stairs to the loft story, reasonable ceiling heights, or generally pleasing layouts so don’t plan on having your AI image generator develop your floorplans any time soon.
• All chose a similar aesthetic for the coffee shop though Reve was the only one to focus on a detailed closeup. The presence of text in this prompt also showed that all except PromeAI and Firefly nailed the spelling on the first attempt.
• For Solarpunk, Reve, Vizcom, Nano Banana, Imagen, Ideogram, Flux, Firefly, and Dall-E envisioned a glassier more technological future while Canva, Midjourney, and Recraft leaned in the more traditional architecturee direction…. all with plenty of plants of course.

Selecting The Best AI Image Generators for Your Project

Now that we understand the general vibe of each AI model, you need to decide which type of platform best fits your design goals. Most image generator tools can be broken down into the following categories:

1. High-Creativity (Low-Consistency) Tools
2. Constant Composition Tools
3. Sketch Rendering
4. Creative Fusion

High-Creativity (Low-Consistency)

This type of AI image generator needs no introduction. It is the type of tool covered in the last two posts [Post 1: Art Nouveau] [Post 2: Art Deco and Workflows] and throughout the news recently. For more information on how to leverage these tools, follow the links above.

In my opinion, the best AI image generators for high-creativity brainstorming early in design are Midjourney and Gemini Nano Banana. Almost every AI image generator offers this capability (excluding Veras and similar 3D model focused plugins) but their quality, speed, and versatility varies. This type of tool is most impactful at the very start of a conceptual design phase. You can review the infographic above to determine which platform best fits the styles you want to explore or craft your own benchmarks for your use case.

A high-creativity model is excellent for brainstorming, but is terrible at maintaining consistent composition or massing between generations, meaning elaborating on a design concept can be challenging.

Constant Composition

Constant composition tools are a style of image-to-image that take a reference image, apply some noise or blur to it, and use that as the background noise instead of the white noise field Midjourney and other from-scratch high-creativity image generators rely on. This maintains the general composition of the reference image and lets you reimagine it. You can also vary how closely the result should match the base image.

A good example of a constant composition tools can be found in Midjorney’s retexture feature, Gemini Nano Banana, Veras, PromeAI, and Vizcom among others, allowing for rapid variation. They can produce specific aesthetics like cinematic, realism, or my personal favorite…. knitted which turns everything into yarn (See slide 12 below).

The following flipbook provides a good example of constant composition using a futuristic solarpunk art nouveau veranda as the base image. I used a variety of ai rendering prompts to quickly reimagine the scene. You will notice this model retains but reimagines the focal points, key elements, and strong lines of the original image in new and surprising ways.

With filters and creative fusion, you can discover and analyze different styles to produce amazing results with minimal knowledge of prompting or art styles (but you might learn a few things along the way).

Sketch Rendering

Sketch rendering is another flavor of image-to-image that offers even more control. Already have a sketch or 3D model of a building but can’t be bothered to pick materials and sit around waiting for it to render? With the latest AI image models in 2026 you can sketch render it in platforms like Midjourney, Vizcom, Veras, or PromeAI.

Each of these took mere seconds to create. Starting to sound a lot better than your average render time isn’t it?

Creative Fusion

Let’s say you want to combine concepts from two buildings into a single image that uses the massing of one but the style of the other. If you combined these two in Midjourney, the result would be a completely different building than either of the two inputs as shown in the image prompting examples of a previous post.

If you attempted this in a constant composition or sketch rendering platform, you would quickly realize your options are limited to loosely controlling the composition of an image directly, while the style still needs to be described entirely with words.

Platforms with Creative Fusion offer a more intelligent way of combining images by taking the geometry/massing of one and applying the style/articulation of another, creating some truly striking results.

PromeAI and LookX have had tools in this category for a while. However, more recently Vizcom has released its own creative fusion tool that I can only describe as an absolute triumph of creativity. This will be covered in more detail in a future post, but one exciting application is when you want to apply the style of one project to a building with a totally different building type or size. To start, here’s an example of applying a unique art nouveau-inspired style to a drab looking apartment building using Vizcom:

Workflow Building – How to Combine Platforms

Brainstorming

Combining platforms requires the designer to determine the best AI image generator for each step of the design process. In general, it is best to start with either an existing image or one of the many high-creativity platforms to brainstorm.

Within your selected platform, it is often possible to supercharge your brainstorming and further develop an idea through remixing, image chain prompting, panning/zooming/outpainting, inpainting, prompt engineering, and various other tools which are are being introduced to the design landscape on a regular basis.

Conceptual and Schematic Design

After you have developed a concept you are satisfied with and want to set some of those design decisions in stone, the goal should be to move to a platform that offers more control and less creativity like one with constant composition (e.g., PromeAI), sketch rendering (e.g., Veras, Vizcom, or PromeAI), or creative fusion (e.g., Vizcom, or PromeAI).

Once you start developing 3D models, you can continue to involve AI image tools through model screenshots (such as with Vizcom) or with plugins like Veras to explore design options across multiple views of your 3D model. This lets you refine the model as you go by having the AI focus on elevations, plans, or specific details to imagine what they might look like and offer rapid rendering capabilities. Tips and workflows for this type of model-centric design will be covered in another post on AI image to 3D workflows.

Next Steps

Finally we reach the end of what AI image generators can typically accomplish in 2026 (though that could easily change any day now). Future posts will further define these limitations, but this need not be the end of the road for AI-assisted design on your project. Other tools like LLMs, AI optimizers, AI code/performance analyzers, AI architecture rendering engines, AI video, and other generative design tools can all play a role as the design progresses.

It’s an exciting new world for architectural design but with creativity and continuing education, the architects of today should have the tools to thrive in it.

Coming up…

In this article, we analyzed how the best AI image generators handle a modern organic home using a predefined benchmark prompt. In a related post, we use variations of this idea in an exploration of prompt engineering to experiment with the Midjourney algorithm, understand its underlying mechanics, and explain how to use those concepts to craft your own prompts.

The post The Best AI Image Generators for Architecture in 2026 appeared first on Pixels to Plans.

In the evolving field of architecture, effectively merging AI-generated 2D images with your 3D modeling workflows is essential. While the holy grail of AI tools for architects would be one that generates BIM models directly from text or images, current AI 3D tools primarily cater to character and game asset creation, lacking the specificity required for architectural design. Therefore, architects must develop innovative workflows that combine various AI tools to bridge this gap.

In this AI Tool Tip, we’ll look at a quick way to convert a 2D architectural concept image (be that a sketch, photo, or AI generated image) into a 3D model and create consistent, high-quality renders of it from any conceivable angle with only minimal 3D modeling effort.

AI Tool Tip: Bridging the 2D to 3D Gap

This guide demonstrates how to produce comprehensive concept renders from multiple angles using minimal 3D modeling, leveraging the AI rendering engines best suited for architecture.

Step 1: Generate a Base Image

Begin with an initial concept image or sketch. For this one, let’s select the gnarled and knotted sunrise prairie lake house from a previous post.

There are countless image generators that can help with this phase. For a comparison of the best AI image generators to help you decide which might be best for you, click here.

Step 2: Create a Rough 3D Massing Model

Use a free vanishing point calculating software like FSpy to determine the image’s perspective and export it to your 3D modeling tool of choice. For this example we will be using Blender, a free opens source 3D modeling software. You can learn how to use and download FSpy here and you can download Blender here.

With these tools, we can construct a basic massing model to establish the structure’s form.

Step 3 (Optional): Apply UV Mapping

In your 3D model, apply UV mapping to project the original image onto the massing. This step, while optional, helps maintain consistency in textures and features, preventing the final AI rendered image from deviating too far from your initial concept.

Step 4: Capture Model Snapshots

Capture snapshots of your model from various angles, including close-ups, plans, elevations, and perspectives. These snapshots will serve as foundations for your AI-rendered final images, aiding in detailed modeling and presentation.

Step 5: Generate your AI Renderings

Employ AI rendering engines to enhance your snapshots. Input the base image to generate a descriptive prompt, then use this prompt alongside your snapshots and your initial image as a style reference to create refined renders. Several AI tools are available for this purpose:

• • Midjourney and Vizcom: These platforms preserve the original massing effectively but may produce textures that appear slightly artificial.
  • Recraft: Generates creative results with a stylized, video game-like aesthetic, though it may alter the original massing.
  • Krea: Offers adjustable editing strength and a distinctive, crisp style, allowing for quick iterations.

The Canva infographic below shows the full results of each platform used in this study. You can zoom in to see the differences between each image at the Canva link below.

2D - 3D AI Workflow Comparison by AcanthusAlchemist

Each tool has unique strengths and limitations. Selecting the appropriate platform depends on the desired style and project requirements.

Alternative AI Methods for 2D-to-3D Conversion

While the above method involves manual modeling, other AI-driven approaches can provide insights into transforming 2D concepts into 3D forms:

AI Video Tools (e.g., Luma Labs):

These tools can be used to generate 3D turnarounds or flybys of a building from a 2D image, offering a dynamic perspective on your concept. These are not the most easily controlled or faithful method and often require keyframe images or a video of a rough 3D model as guidance, but it does give you a better idea of how your AI generated concept might look in a 3D space. Some examples from a few different projects are shown below:

Image-to-Mesh Tools (e.g., Krea 2D-3D):

Krea can create a rough 3D mesh from a 2D image, allowing for interactive viewing and re-rendering from different angles. However, exporting these models is not currently supported, and the meshes may lack architectural detail needed to really use this developing the design. It is a new technology suited for early concept exploration, but it may soon develop into something much more powerful.

While these Image-to-Mesh and Image-to-Video methods offer alternative perspectives, one should note that currently you may find they often won’t provide the precision required for detailed architectural modeling.

Problems in the AEC Industry

 We’ve all seen it. Rows and rows of drab uninspiring buildings, interior designers turning everything a mix of gray and beige (a.k.a. greige), and hulking modernist cubes that pretend a few square pop ins and pop outs make them “fun”. Even their designers curse these buildings when told they need to work overtime on the client’s umpteenth redesign request. So what might save us from this architectural inhumanity? Surprisingly…. generative AI tools.

From the cost, to the impermanence, to the inefficiency, to the overall drabness, the architecture and the AEC industry over the last 50 years or so has its problems. However longtime readers of this blog may be aware we may be on the verge of a new era in architectural design… an explosion in efficiency and architectural creativity fueled by generative AI tools in the AEC industry.

So how is AI going to tackle the problems so many people have with architecture and the AEC industry today? What is the case for why there should be no more boring buildings? Let’s find out.  

Key AI Tools and Trends in Architecture

After researching and writing about AI in architecture for over a year now, here are a few of the key trends I’ve found that will impact the AEC industry: 

Conceptual Design:

It should be no surprise that AI is making conceptual design much more accessible, as we explore in other posts. With AI tools like Midjourney and  ControlNet on Stable Diffusion, you can imagine countless concepts on a given site with a few brushstrokes and the click of a button, as demonstrated by architect and AI educator, Design.Input. Thus, in the future when creative design choices are just a click away, there will be almost no excuse for boring architecture.

It will also allow for much more abstract concepts. While text to image is the way most people prompt, the truly creative among us rely on image-to-image prompting. This lets them integrate disparate concepts like a breathtaking landscape, the foam on a latte, or a crumpled-up piece of paper to create truly novel design concepts.

There are countless image generators available now that can help with this phase, but for comparison of how some of the more established AI image generators perform, click here.

Making Program and Performance Decisions:

Outside the realm of concept renders, AI-powered tools like Maket and PlanFinder can generate an endless array of floorplan options to make design decisions [1] [2]. Another platform, Finch3D, provides not only layout options, but also performance optimization, enabling designers to generate and refine plans optimize their efficiency in terms of useable space, daylighting, etc. [3].

Developing Design Options:

AI can retexture and render designs in varied styles, materials, and color palettes, empowering designers to explore thousands of options quickly. With tools like Krea realtime generation, Midjourney Editor, and Stable Diffusion with ControlNet, designers can swiftly visualize variations, making it easier to handle redesigns without the time-consuming process of designing and rendering several more design options via traditional methods. 

Until recently this was reserved for 2D images in the conceptual design phase. However, with parametric modeling alongside real time AI rendering like Krea, AI Revit plugins like Veras, and AI video-to-video platforms, some innovative designers are starting to bring AI into the 3rd dimension in later design stages. One example from Studio Tim Fu (a firm that focuses on using AI in architecture design) studio shows the full evolution of a tower concept from boring cylinder to pinecone-inspired, balcony-studded statement piece building while in another study his studio experiments with using text-3D AI to generate massing concepts, renderings, and physical models. 

Note: Accepting cookies may be required for embedded videos to work on your browser.

Furthermore, AI can even identify potential design flaws by attempting to fill in the blanks of a concept sketch lacking in detail. This helps designers catch issues like missing windows or illogical roof transitions early in the design process. 

Understanding Client Preferences:

Struggling to capture a client’s vision, despite hours spent on meetings, mood boards, and options? Tools like Midjourney’s personalization feature can simplify this process by adapting to a client’s aesthetic preferences in a user-friendly, algorithmic way.

In Midjourney, clients can indicate preferences by liking images or choosing between options, much like how YouTube or TikTok algorithms learn user tastes. This creates a personalization code that can automatically adjusts the lighting, colors, and styles of your renderings to match the client’s unique preferences, capturing subtle tastes often hard to communicate in a design brief. This tailored approach can help clients get excited and approve designs faster with fewer revisions.

Code Compliance:

Large Language Models (LLMs) like ChatGPT excel at scanning and explaining dense text, which could one day help architects review code requirements with much less effort—if they can overcome their biggest flaw: hallucinations.

A “hallucination” is when an AI confidently presents incorrect information, such as counting errors or fabricated sources. While AI can answer simple questions, you must always verify its answers to avoid errors. One way AI users are reducing these issues is by training custom models on more curated training data. Custom GPTs or LLMs based on vetted sources offer more reliable responses than general models, which may includes unverified data and might just respond to your serious code compliance question with a joke answer it found on Reddit.

One company, Perplexity AI is addressing this problem by training their model trained to consistently prioritize citation backed responses. It is more targeted at researchers and assisting technical professionals. This makes it more reliable, though as always backchecking is critical.

For comparison, we asked three free LLMs to answer a question about roof insulation requirements in California and looked up true answer separately in the 2022 California Energy Code. Here’s what they came back with.

This question was intentionally vague, but as you can see Perplexity did fairly well with the only citation-backed response and gave a technically correct answer for nonresidential roofs, though it missed many key details and said this applied specifically to wood framed buildings. It did calculate the correct effective R-value from the code’s mandatory U-factors though.

ChatGPT was also sort of right from a practical standpoint by suggesting two common nominal R-values for insulation products used to meet code requirements, but its response was full of unhelpful generalizations, it was missing citations, and it did not correctly report the exact language in the code. Lastly Gemini grabbed a number from the residential requirements, but didn’t report climate zones correctly and did not cite the source directly. 

However, the most important finding among all three is that LLMs are trained to give you an answer, not ask the right questions, and there are many questions the AI should have asked to determine what type of building it is, what climate it’s in, etc. to determine which code sections apply.

3D Scanning and Field Measurements:

Measuring and drafting plans for existing buildings can be a tedious process, with designers often missing key details. Fortunately, several AI-powered 3D scan-to-floorplan platforms, such as Polycam, Scanniverse, Matterport, and LumaLabs AI Interactive Scenes, are making this easier [2][4][5]. These tools use advanced technologies like LIDAR, SLAM, point clouds, NeRFs, and Gaussian splatting to create digital twins of your project.

Though integrating these systems into your practice may seem costly, some are as simple as installing an app and taking photos. We’ll review the pros and cons of each in a future post.

Cost Estimating AI:

How often have you come up with a design you love, only to find out after pricing that it’s way over budget and will be hacked to pieces by value engineering? Well, that may become a thing of the past now that AI cost estimating is starting to hit the market as well.

While this technology is still new and not yet accurate enough to replace estimators, it can assist them by speeding up their workflow [6]. Tools like Togal.AI [7] automate tedious takeoffs, and the industry is already exploring how AI can support 4D BIM (accounting for time and sequencing) and 5D BIM (accounting for costs).

With faster, more reliable cost estimates, project teams could soon run cost-benefit analyses on numerous design iterations in record time (under the guidance of an experienced estimator of course), allowing architects to discover cost saving design strategies they might have never discovered based on intuition alone. Many assume that stark modern boxes with a few pop-outs to represent “motion” and “intersecting masses” are the most budget-friendly option, but AI tools may help project teams discover innovative ways of making more expressive and affordable facades. Thus, discovering savings this way may play a key role in solving the world’s housing affordability crisis.

Introduction

In a previous post, “Seasonal Color Analysis for Architecture and Interior Design” we explored the power of color palettes when prompting in an AI image generator. At the end of that post, we invited readers to comment with their favorite color palette they would like to see more of. As of this writing there was only one comment so I guess we have a winner: Dark Autumn. 

Without further ado, in this entry into our Style Bytes series, let’s delve deeper into the rich and evocative dark autumn color scheme as we explore its potential for architecture and interior design.

Concept: Dark Autumn Design

The dark autumn concept is more of a palette than a style, but it does draw from a real style that is gaining in popularity recently too: Dark Academia [1][2][3]. The aesthetic used in the images above relies on a rich and cozy aesthetic and was inspired by fall colors, Tudor revival, and dark academia decor. It has half-wooded facades, dark and intricate interior millwork, plaster and stonework, cozy traditional furniture, dramatic windows opening up to lush landscaping, and vivid autumn colors such as purple and orange. 

This design aesthetic is characterized by its contrast of rich and rusticated materials and colors, often inspired by the natural hues of the falling leaves and the darkening sky.  The dark autumn palette typically includes shades of brown, burgundy, deep orange, and black. These colors are often paired with neutral tones like cream, beige, and gray to create a balanced and inviting atmosphere. Alongside these colors comes gothic detailing and dark academia flourishes. Some warm lighting choices such as candles and café lights, alongside fall-inspired decor, such as pumpkins, leaves, or gnarled branches complete this witchy, Halloween-ready look.

AI Design Methods

To bring these design concepts to life, we at Pixels to Plans utilized a combination of AI tools, primarily Midjourney, and experimented with prompts that focused on reimagining Tudor architecture with a futuristic twist while maintaining the core elements of the dark autumn palette. Prompts varied but if you’re interested in designing in this style yourself, it can be easily replicated using your preferred platform’s style reference feature without any complicated prompt structures of workflows.

However, if you’re interested in AI visualization techniques for home design or in learning the specifics of the workflow for any particular image, leave a comment below. 

AI Explorations: Dark Autumn Design

Residential Applications

Let’s set our initial focus on home decor with a classic yet spooky vibe and ask the question: Why can’t Halloween be every day? We begin by exploring the potential of the dark autumn palette in creating inviting and intimate living spaces.

• Cozy Bedroom Retreat: A dark autumn bedroom offers a sanctuary of relaxation and comfort surrounded rich wood finishes and breathtaking views. 

• Traditional Kitchen with a Modern Twist: These design ideas blend historical, more traditional Tudor style elements with contemporary aesthetics for a functional yet stylish kitchen.

• Art Nouveau and Tudor Fusion: This concept throws in the curves and organic forms of Art Nouveau alongside the classic half-wooded elegance of Tudor architecture for a throwback architecture style worthy of The Shire.

Larger-Scale Development

Expanding beyond the realm of interior design and into facades and architectural design, let’s look at how the dark autumn aesthetic could be applied to larger-scale residential developments.

• Hillside Estates: These Tudor-inspired estates offer breathtaking views while maintaining the core elements of the dark autumn palette. 

• Intimate Cottage Living: Alternately we could imagine a row of denser, more compact homes that embrace this dark autumn aesthetic, creating cozy and charming living spaces with cottage rowhouses.

• Urban Courtyard Living: These images showcase how the dark autumn palette can be adapted to multi-family housing on a larger scale with intricate facades surrounding a dramatic courtyard, creating a sense of community and intimacy.

Modern and Futuristic Interpretations

To demonstrate the versatility of the dark autumn palette, we can experiment with some more modern and futuristic interpretations of the style.

• Dark Autumn Historical Futurism: This concept pushes the boundaries of the dark autumn aesthetic by incorporating more modern and future-forward elements like all-glass walls and blending in more vivid colors and surreal lighting.

• Detailed Patio Design: Finally, zooming out a bit to focus on exterior spaces, the following images highlight the potential for intricate and inviting patio designs within the dark autumn framework.

The Firehose of AI Content

As the role of AI in architecture evolves, generating novel styles and keeping them consistent with style reference tools will soon be a critical part of the design process of all architects. 

Now you may ask, why? In a recent opinion piece for Building Design Online, when discussing the future role of AI in blending tradition with innovation, architect Andy Shaw writes “Artificial intelligence is enabling the design of more expressive buildings, which fuse a myriad of cultural references to create a new vernacular that transcends traditional architecture’s approach to decoration.” I entirely agree with this sentiment, but when most people see the firehose of random crazy-looking AI architecture photos flooding the internet, that begs the question: How can we expect AI to start a real design movement? If everyone is always doing their own thing or moving on to the next idea that takes 10 seconds to generate, how can any one design concept get the momentum and public acceptance it needs to be built on a large scale?

Well, with the development of style reference and creative fusion features across all major AI image generators, it has never been easier for architects using AI to take an image of one of their buildings, or of a style they want to study, and expand upon it. In minutes you could take your unique concept for a house and get ideas for how to apply your original style to an apartment, a community center, a skyscraper, a streetcar, a city plan, or a sofa. 

The ability of AI to help designers envision their ideas in a novel context is unmatched and will allow architects to effortlessly produce entire portfolios, even masterplans, in an original style they truly want to design. All it takes is a concept and the curiosity to ask how far that concept can go.

An Introduction to Style Bytes

This post will be the first in a series of posts called “Style Bytes”, each exploring a style I have been working with lately, from the familiar, to the novel. Each post will explain the core design concept, list key features, and provide some examples of the style applied to different contexts. 

I predict that exercises like Style Bytes, where architects use AI style references to evolve one idea into an entire family of design concepts, will become a key part architectural practice as AI tools become more widely adopted. 

Furthermore, platforms for sharing, discussing, and remixing these ideas will provide the constructive criticism and consensus-building needed to turn the firehose of random AI generated content into actual focused and feasible design movements as communities coalesce around entirely new design ideas for the 21st century. 

So, let’s take a look at our first Style Byte, Sunrise Prairie.

I stumbled across this concept in the brief but exciting existence of BlueWillow (sadly no longer publicly available) to create the image above using the following prompt:

futuristic art nouveau solarpunk prairie style architecture, organic shaped, intricate ornate filigree detailing, highly detailed, Frank Lloyd Wright prairie style, 3D printed architectural villa, with long glass windows, accent lighting, chaparral landscaping, illuminated pond, during a bright foggy sunrise, archdaily photo, photo of intricate ornate architectural detail, close-up, window filigree detailing, architectural close-up detail photo –ar 3:2

It didn’t quite get the close-up or chaparral right. Instead it did more of a marshy prairie landscape typical of Frank Lloyd Wright’s midwestern projects, but what it did produce were questions and ideas. These included:

• The harp-like vertical wood stiles wood on the east wing. Are they a brise solei? A trellis?
• The horizontal striations along the façade. Could this be a 3D printed concrete, striated sandstone, or rammed earth construction, or maybe it looks better as just weathered wood shiplap?
• What could be causing the warm orange glow around the windows? Is it an interior design choice, a warm brassy finish on the windows, a lighting choice, or just sunrise reflections
• What’s going on with the roof line? Maybe a roof terrace or undulating standing seam metal roofing.
• The back slope on the east and west wings, giving the building a ship-like appearance sailing through the marsh. This is effectively an elevation, so how is the rest of this building shaped and what might the other side look like?

Even though we’re just looking at a statistically probably jumble of pixels spit out by a machine, it’s questions like these that challenge architects to refine what they see and identify a concept for their design process.

One could argue that a picture is worth a thousand words so the overall “vibe” of this image is the concept, but if I had to summarize it in words, this opulent home’s concept is that it’s a place of warmth, horizontality, and craftsmanship, existing somewhere between a rustic old shipwreck on the lakeshore, and a sandstone riverbank, reminding you of the dynamism it took to carve:

The Importance of Style References

Before we can dive into this Style Byte in earnest, we need to first look into why a reference image is important. For example, with the exact same prompt but no reference image, Midjourney goes in an entirely different direction, with wild organic curves. It loses a lot of the prairie style influence and specific details noted above. Here are some examples from Midjourney versions 4, 5, and 6 showing a consistent bias towards unrealistic forms. 

Compared to text prompting alone, Midjourney’s three forms of image reference tend to work a bit better (Image reference, style reference, and character reference) but it is up to the Midjourney user to determine which methods are most effective for their particular project.

Style reference can even be used to enhance an existing image. By feeding the same low resolution image into Alpaca AI Rendering as both the subject and style reference, you can create a higher quality image and refine some of the sketchier details earlier AI models struggled with.

This goes to show that style reference images are absolutely critical for consistency in this type of design process. Once again, a picture is worth 1000 words. Now let’s use this feature to explore different applications of this “Sunrise Prairie” style.

AI Explorations: Sunrise Prairie

Like many designers, I felt the need to expand upon this concept by improving the image quality, creating ideas for the interior and other exterior views, and imagining other buildings in this style. Using our existing image of a long, narrow “Sunrise Prairie” Style estate as the concept, let’s explore some more ideas using this style:

Bit 1: 

Some nearby estates in a Sunrise Prairie style.

Bit 2: 

Some interior shots of intricate millwork, bespoke furnishings, plus an affinity for wood and water.

Bit 3: 

This community needs a downtown so maybe we need a stylish office building in this neighborhood or an elegant community center.

Bit 4: 

How about some concepts for a commercial area?

Bit 5: 

Now obviously you may have realized no one can afford these first several options. But we can help fix that with style references. The concepts you develop one day for a custom home could soon be optimized and reimagined for more affordable large scale production. So lets start thinking more in terms of density. How about instead of our long narrow mansions and institutional buildings, we have string of apartments along a courtyard walking path?

Bit 6: 

Of course we don’t want this to be a car-centric exurb, so we definitely need to locate this around some transit.

Bit 7: 

What if you just want a little slice of this style to call your own? In that case we can use style reference tools to imagine this seemingly grand and opulent style scaled down to the manageable size of a small, cozy cottage of the future.

Bit 8: 

And finally, what more can we do to convey what it might be like to experience this Sunrise Prairie style? One word: Motion. So, with a little help from the animation tools of Immersity AI to turn 2D images into 3D depth maps and videos, along with inspiration from AI architecture luminaries like Iosif Gkinis and Sebastien Ollier, we can bring these concepts to life.

AI News Update

On October 25th, 2024, the platform covered in this post (Alpaca AI Rendering) will be permanently shutting down. However, don’t worry, there are many similar free AI rendering platforms out there for creatives to fill the gap left by Alpaca and I will be writing a new post soon to review what I think the best alternatives are. To be notified of my next AI platform review and other future posts, and to stay stay up to date in this fast moving, ever-changing landscape of AI image generators, subscribe to the free Pixels to Plans newsletter using the subscription box at the top or bottom of the page. However, if you want to learn about AI rendering more broadly, the following post still provides useful insights you can use on other platforms. Enjoy!

Introduction

If you’re an architect or designer interested in working AI rendering tools into your design process, it can be frustrating finding the right platform to start on. There are countless options but many either have hidden paywalls, lackluster features, confusing UI’s, or just don’t offer the blend of quality and control architects are looking for. However, the goal of this blog is to share the best and most accessible AI tools and ideas for architects to explore this new field of design, which is why Pixels to Plans is excited to share this unsponsored review of Alpaca AI rendering, and show how it offers exactly what architects need in an AI platform.

Alpaca: AI Rendering Platform Review

Alpaca (a.k.a. Chroma by AlpacaML) is a free AI image generator and AI rendering tool currently in open access with some impressive capabilities for architects, especially for rendering and refining your building concepts. At the time of writing, it offers 100 free generations a day, with reasonably priced options for standard and pro plans, but for most architects looking to experiment and learn AI render tools, the free tier is plenty. You can get started experimenting with Alpaca for free at AlpacaML.com.

One of the issues with many competing AI models is a lack of authorship (i.e. how much control you have over the results compared to the algorithm). A platform with poor authorship means the algorithm makes most of the decisions for you and while its results might look good, it doesn’t take direction all that well and you often can’t reliably edit the generations you get.

Alpaca fixes this issue. Its sketch-to-render and editing tools let you turn everything from well-developed Rhino models to even the worst Microsoft Paint doodles into stunning images. It also does this with a fast generation time, giving you constant feedback so you can refine the result by refining your drawing. This gives a tremendous amount of authorship to the user and makes fine tuning images a breeze compared to the uncontrollable slot machine that platforms like Midjourney provide (still love you though Midjourney).

However, in the realm of architecture, it provides something even more powerful: constant massing. If you input a picture of a building or even just a massing model, Alpaca lets you generate high quality variations in finishes and style while maintaining the same general shape of the building. Imagine being able to produce a hundred high quality renders of finish options for your building in a single day, or even completely redesign the facade with the push of a button. That is the power that Alpaca gives you.

While it may not have all the advanced features of other platforms, for architecture it is a godsend because it allows you to generating high quality building images that explore different style or material alternatives for a given massing. Other models such as Stable Diffusion can yield similar or better results, but these come with a steep learning curve and don’t always maintain the massing as well on the first try. Based on my tests so far, Alpaca is the simplest and most reliable model I have found for AI rendering tasks.

As you will see in the next section, compared to how other free and paid models perform on this task, this is groundbreaking.

Example Projects

Of course, as with any AI image generators, why describe their capabilities when you can show them? So, let’s take a look at some benchmark prompts and example use cases of how Alpaca performs to show how architects might be able to apply this tool. We will be looking at the following examples: 

• Façade Variations
• Physical Model to Render
• Updating Your Portfolio
• Sketch to Render for Adaptive Reuse
• Interior Remodeling

Constant Composition

In Post 3 (The Best AI Image Generators for Architecture) we explored the concept of style benchmarks for assessing how a platform interprets prompts. Let’s look at our five Pixels to Plans benchmark prompts to get an initial idea of how this model performs.

To compare these against the same benchmarks on other models, check out

Fortunately, Alpaca interprets prompts very similarly to other platforms so if you are used to another image generator, you can often import your favorite prompts over to start integrating Alpaca into your workflow and get similar results, without having to reinvent your prompts that much. To test this out, I used ChatGPT to generate prompts in a consistent format for X styles using the prompt template below:

Prompt Template: Architecture photo of a house in a [style] style, [adjective] facade of [materials]. [Details] prominent throughout the design, with [focal points or other key features].

Then I took the following art nouveau-inspired home concept I generated previously as my base image for the experiment.

I ran this base image with each of my ChatGPT generated prompts in Alpaca to assess how well it maintains the composition while capturing a variety of styles. For comparison, I ran the same prompts using Stable Diffusion XL (SDXL) on Playground AI and achieved the results shown in the second column using a 20-30% image weight (which took several iterations to optimize).

You may notice that SDXL adds a bit more detail and texture quality to the images, it isn’t as good at maintaining consistent massing and struggles to change out all the finishes to match the prompt as well as Alpaca Alpaca. With enough prompt engineering (See Post 4), negative prompts, and varying the weight of the base image, you can achieve higher quality images with Stable Diffusion, but for the average architect just looking to quickly create some cladding variations for their existing design, Alpaca Alpaca is the superior and more user-friendly product.

However, let’s say you like the look of SDXL but the control of Alpaca? Well, why not just combine the two in a single workflow with Alpaca’s creative fusion feature? The third column shows the results of painting the style of the SDXL results onto the final image using Alpaca’s creative fusion.

You can zoom in on Canva to better understand the nuances of each output. 

AI Architecture Rendering Tool Comparison by AcanthusAlchemist

Hopefully shows that for simple variations, Alpaca really shines, but for designers to really embrace AI in their workflow, they may need to understand the strengths and weaknesses of all the platforms they use, and learn how to combine them to fit their design goals.

Physical Model-to-Render

When I was in high school, I wanted to be an architect so when I got the chance to model a building in our “prototyping” class, I jumped on the chance to make a physical model of an original building inspired by my favorite architect at the time, Frank Lloyd Wright. This building was in FLW’s Usonian style (learn more about Usonian architecture at the link below) but the model was rough at best. However, with an AI like Alpaca, I was able to reimagine this model with a much more realistic visualization.

Tools like this will be transformational for both architects and students to express their creativity in ways never before seen, with little more than some paper, glue, a camera, and a prompt.

Updating your Portfolio with AI Rendering

Let’s say you have a portfolio of well-developed designs but you’re not too happy about some of the finish choices you made. Or, maybe some of your past concepts aren’t in style anymore and you’re trying to update your existing portfolio of ideas to fit a potential client’s requests. Well, why not use an AI architecture rendering engine like Alpaca to reimagine your portfolio in a different style? 

For example, let’s say you want to take your brighter, more fantastical ideas in a darker, warmer direction with some Usonian influences. Well with a few keystrokes you can do this:

Prompt Template: Architecture photo of a house in a Usonian style, rain and fog, dark rich wood, glass, copper, overcast, Cherokee red concrete, fir trees, open breezeway, flagstone, flat roofs with overhanging eves, warm orange light in the windows, at dusk, front entrance

Sketch-to-Render for Adaptive Reuse

As noted above, a key feature of Alpaca is its MS Paint style tool that lets you prompt with drawings rather than words. To me, Alpaca seems to be the best free AI tool for turning illegible sketches into something beautiful compared to its competitors.

I believe this will be particularly useful for adaptive reuse, helping to visualize how obsolete or unwanted structures could be repurposed. In particular, the paint sketching feature could help architects add decorative flourishes and critical changes to the massing of existing buildings with unparalleled precision and quality. 

As an example, let’s consider a less car-centric future where parking structures might be reused as office space or housing. Sure, there would need to be some major structural and envelope changes like adding lobbies and balconies, or removing some floorplates for higher ceilings, but this tool can help architects make the fine-tuning changes needed explore what those changes might look like, helping Owners envision how they could repurpose these structures.

AI Rendering for Interior Remodels

Finally, as usual, let’s not forget about the importance of interiors. Using a workflow that blends Midjourney and Alpaca, I was able to consult on a small bathroom remodel, helping the homeowners rapidly visualize how their bathroom might look with the specific tile, vanity, and mirror they were considering, taking real-time feedback and giving real-time image updates in a fraction of the time it would take to model and render such a detailed finish concept from scratch. 

The Canva slideshow below shares a few snapshots from the visualization workflow. This includes a photo of the initial bathroom, initial Alpaca renders before finishes were narrowed down and priced, a Midjourney exploratory phase for visualizing randomized finish arrangements with the initial Alpaca output as an image prompt, and finally a Alpaca phase for dialing in the image by adding the toilet, mirror, structured ceramic bronze tile niche, and backsplash that Midjourney struggled to put in the right places. While Midjourney and Alpaca are not perfect, together they are great for getting a feel for how specific materials will work together in a space.

History

Origins: Organic Architecture and The Prairie Style

Frank Lloyd Wright is a giant in the history of American architecture with a fascinating personality and an immense variety in his architectural style. This is a man who reportedly designed his most famous project, Fallingwater, in less than 3 hours when faced with a surprise visit from his client after procrastinating for months on end [1] [2]. On the flip side, he was also someone who meticulously designed every detail of his works from the façade, to the furniture, to even the forks [3]. 

From open plans and textile block to solar-centric design and site-conscious organic architecture [4], his ideas are ubiquitous in modern architecture discussions and many other late 20th century styles all borrow an idea or two from Wright. Though his ideas remain popular, today designing buildings in the Usonian style he championed is not.

Frank Lloyd Wright (FLW) is best known for his large projects and prairie style, which was a design movement focused on large low-slung estates sporting low pitched hip roofs, stained glass, ribbon windows, and strong horizontality that harmonized with the flat prairie environment of Wisconsin and Illinois.

In all of FLW’s works he designed spaces like a series of overlapping Venn diagrams often radiating out in an L or pinwheel shape. Rather than separating rooms with walls and doors as was common in the late 1800s when wright began practicing architecture, his rooms would overlap at their diagonals to create multi-use, simultaneous spaces and offer occupants many perspectives of their use. Kitchens would flow seamlessly into dinettes and then into living rooms, and so on. Rather than trying to cram all these uses in a predefined massing like a postmodern design might do, Wright let the plan define the massing of the building, which he called “Organic Architecture”. Some other guiding principles in Wright’s designs include:

• Separate common spaces not with walls, but with bulky objects like built-in furniture or chimneys. These components act like screens since they don’t connect with all floors, walls, and ceilings, maintaining some privacy but making things seem connected.
• Make liberal use of corner windows to improve interior/exterior connection.
• Design buildings inspired by the surroundings landscape that appear at home in their environment.
• Avoid designing boring boxes and stop treating buildings like “machines for living” [5]. After all, Wright once said “The box is a fascist symbol and the architecture of freedom and democracy needed something besides the box.” (video below) [6] Thoughtfully breaking up massing with corner windows, dramatic wings, and equilateral triangular plans enlivens the structure.
• Use architecture to convey philosophical ideals such as freedom of movement or lack of confinement, and political notions of democracy and choice.

Designing for Density: A Usonian Style for the 21st Century

We’ve discovered how to reproduce a Usonian style and how to meld it with your site using AI, but how do we expand on it for the modern era? For that I propose the following design goals:

• Prioritize Scalable Designs – Develop concepts that are scalable, accommodate density, and have a broad appeal (we have a whole housing crisis to solve after all).

   

• Use Human-centric Plans – Wright’s method of organic architecture was to set the room layout first based on how people experience the flow of spaces, then design the building around that. This would frequently result in a simple, but appealing L or T-shaped plan. While image generators usually struggle with technical drawings like plans (more on that in a future post) this principle can help us pick massing ideas from the AI that can accommodate these organic plans, while discarding both uninviting minimalist boxes and unconstructible overcomplicated McMansions.

   

• Harmonize with Nature – The concept needs to visibly have site responsive design like solar exposure and minimizing impact on its surroundings – concepts FLW frequently explored nearly 100 years ago long before the concept of sustainable design existed. In urban spaces where there isn’t as much nature left to disturb, we should still aim to reintroduce nature back to dreary urban spaces.

   

• Reflect the Landscape – The style needs to adapt based on its location. There is no one size fits all. To expand beyond the Prairie, we need a version that blends with the Rockies, a version that camouflages with the redwoods, a version that embraces the Mississippi, etc.

   

• Use Warm Inviting Materials – Draw from FLW’s material palette to evoke a warm, inviting, and earthy, yet elegant sense of harmony. Any architectural statement pieces or higher-priced materials  should be limited and surrounded by otherwise repeatable and humble materials in keeping with the goals of FLW’s initial bet with Herbert Jacobs. (e.g. red tinted concrete, stucco, brick veneer, or horizontal plank siding, which are all common materials in Usonian designs) 

While it’s a challenge to hit all of these at once, these will be our guiding principles.

Let’s consider bullet #1. All of Wright’s Usonians were single family detached homes in rural areas – hardly a sustainable option for the 21st century. In fact, when Wright proposed his Broadacre Plan [11] he clearly didn’t see the drawbacks of such low-density development, which we see in today’s suburban sprawl. How can we improve on this? We could consider something antithetical to his 19th century sensibilities…. Multi-family; shocking for a man who once said everyone would have an acre of land and get around by helicopter in the future [12]. So, let’s imagine what some Usonian apartments and townhomes might look like: 

Reflecting America’s Landscapes

For all of his Usonian projects, Wright took inspiration from American landscapes in an effort to create something Uniquely American and divorced from existing popular styles of the early 1900s like those imported from Europe. Usonian is meant to mirror the many varied landscapes of the U.S. These range from falling water blending with the riparian PA landscape (though Fallingwater straddles the line between Prairie style and Usonian due to its size), to the house FLW’s son hovering like a mirage above the Arizona desert. While Wright designed in many different states, he never got to design a building for every landscape North America has to offer. So, in an effort to expand his vision of Usonian as a nationwide design style, let’s develop some landscape inspired concepts for a new age of Usonian design using AI.

As usual, a combination of carefully engineered text prompts and image prompts are the way to go for the most control over your results. For the photos let’s start with some representative Usonians like the Samara House, John Lloyd Wright House, Masaro House, and Pope Leighey House among others and apply them to different environments.

 

How about we start with a mountain inspired Usonian style since Wright never built any Usonians in the Rocky Mountain states. It could reflect the alpine environment as a reimagined chalet where the usual Usonian flat roof is tilted up much steeper to both resemble the mountains and shed snow. Alternately we could imagine it in the high desert with its cozy earth tones, or on a wooded mountainside sitting lightly on the land with piers that mimic the surrounding tree trunks.

 Now let’s imagine a coastal Usonian-inspired home. Consider a house on the banks of the Mississippi that elevates its living spaces above potential flooding but steps down at its periphery to embrace life on the river and blend with the muddy waters, much like Fallingwater. Alternately, maybe we create a sharp and angular home that yearns to be a lighthouse and reflects the craggy rock faces of New England. Switching coasts, we could consider a stone and copper clad home with colors that meld with the ice plant of the Monterey Bay. Or how about a seaside Florida bungalow with a brise soleil inspired by the perforated windows of the Pope Lehigh house and many other Usonians. However, in this context that brise soleil doesn’t just keep out the hot Florida sun, it is also designed to protect the windows from debris during tropical storms. 

In California, there are actually several real FLW projects in the state to use as a guide but even more biomes to work with. From the Fawcett Farm home that translated the Midwest Usonian aesthetic to the fields of the Central Valley [13], to the Clinton Walker House in Carmel by the Sea seemingly sculpted from the yellow bluffs below with patinaed copper roofing to reflect the bluish green of the surrounding ice plant and eucalyptus. There are even protégé’s of Wright who put their own spin on his style for California, such as Arthur Dyson and his more sculptural, curved take on organic architecture. 

To that end, let’s imagine a Usonian for California’s rolling hills, with maybe a few  organic curves to mirror the hills and the “organic” and “crunchy-granola” vibe fitting for the golden state. 

In all of these cases the overall form of the building varies greatly, but deep down that subtle Usonian DNA in the design remains.

The Case for Usonian Design Today

Wright’s signature Usonian style can be found in the roughly 60 homes he designed for middle-class families starting in 1936. However, 60 is nowhere near the millions of homes that could have been built had the US to wholeheartedly embraced this style. A few of Wright’s ideas did make it into the much more ubiquitous and less elegant ranch style that sprawled across the country [14]. However, stylistically and philosophically, Usonians, Ranch homes, and the many other styles influenced by Wright are very different.

Ultimately, the US needs to build a lot of affordable homes in the coming years. The way I see it, when taking on this challenge architects have two options. 1) they can design run-of-the-mill boxes in a sanitized style unloved by the public, meeting the bare minimum of what constitutes a home…. Or 2) architects can use this opportunity to add to their community’s architectural character with simple, affordable, yet thoughtful buildings. 

Usonian design, with its origins in a bet to design that $5,000 house, can teach us some important lessons on building beautiful homes affordably. Thus, architects would be wise to take much more inspiration from Usonian design, which has already proven its cost-effectiveness, livability, and cultural relevance.

Introduction

We are now living in a world where design concepts from completely different fields can be combined with a few keystrokes to create one-of-a-kind design workflows. With AI tools like Midjourney at our fingertips, we can imagine all sorts of crossover ideas. From a Lamborghini-designed line of kitchen gadgets, to beds from unexpected designers, to shoes that will hopefully never exist, we’re at the verge of a revolution in cross-pollination between disciplines. So as an example, how about we explore the intersection of your personal style with architecture and interior design through a mainstay of fashion theory: seasonal color analysis. You may know whether you’re a winter, summer, autumn, or spring, but what season is your dream home?

Prompt Engineering

Introduction to Prompt Engineering

“Prompt engineering” has been a major buzzword this year for futurists explaining what new jobs an AI-driven world might create. Put simply though, prompt engineering is the systematic research and analysis of what makes a good prompt for a given AI task. If you ever have a specific concept in mind but struggle to get Midjourney or similar AI image generators to produce the specific result you’re looking for despite countless attempts, a little prompt engineering might be exactly what you need. So in this article, we will dive into exactly how prompting tends to work in Midjourney, and how to fine tune your prompting workflow to efficiently get to the results you’re looking for.

Today’s Prompting Challenge

In this post, we will be attempting to produce a sensible Modern Art Nouveau Revival style home as our example, however the concepts presented can be applied to any style (Click here for style ideas on Midlibrary.com)

As demonstrated in previous posts [Post 1: Art Nouveau] [Post 3: The Best AI Image Generators] Midjourney excels at producing Art Nouveau style imagery. However, it produces wildly variable results and it can be hard to control how Midjourney interprets it. Results vary from normal but ornate late 19th century architecture to downright alien biological forms, seemingly unpredictably.

This is because the term “Art Nouveau” refers to such a bold stylemost AI image algorithms (but not all) heavily weight it compared to other words in the prompt. Midjourney achieves this weighting by tokenizing its prompts. To grossly simplify, Midjourney takes prompts and converts them to a fixed number of tokens, where each token corresponds to a specific set of concepts, colors, or patterns of pixels that it has learned to associate with that token. Each token activates a specific part of the AI model, which then guides the image generation process to produce results in an Art Nouveau style. Possibly as a result of Art Nouveau’s complexity, it monopolizes many tokens unless an equally powerful phrase or many other words are added to counteract it.

With that background information we can start to engineer our prompts to produce the exact style we are looking for and discover other insights into Midjourney’s models.

Starting Simple

For our first example we will see how Midjourney Version 5.2 Default Style interprets “art nouveau revival architecture” to see if we can get a viable design concept on the first attempt. For all examples the prompts used are listed below the image.

Ok that’s too ridiculous. We need to help Midjourney tone it down a notch. Moving forward, let’s start with the more subdued “Modern Art Nouveau” benchmark prompt developed in Post 3 – The Best AI Image Generators for Architecture. As noted above, for more on benchmarks and to follow along with another style besides Art Nouveau, check out Midlibrary’s excellent showcase of architectural styles in Midjourney by clicking here.

The benchmark prompt and image we will be starting from is as follows:

Much better, but how can we improve it further?

Prompt Engineering Methods

Let’s say these aren’t exactly the results we’re looking for so let’s see if we can improve the output. We will use the same seed for each result to minimize random variation and we will explore the following prompt engineering methods and concepts:

1. Shorten
2. Prompt Dilution
3. Word Order
4. Negative Prompts
5. Linked Tokens
6. Specifying Materials
7. Version and Style

Shorten

The first and easiest way to understand Midjourney’s algorithm is the /shorten command. This command identifies which words the algorithm is focusing on vs ignoring, tells you the relative importance of each word in your prompt, and suggests ways to shorten the prompt while achieving similar results as shown below:

This shows that Midjourney is heavily weighting Art Nouveau, home, and revival, which means we need to reduce their relative strength if we think the results are too biological or fantastical for our “Modern Art Nouveau” goal.

Taking Midjourney’s advice and using shortened prompt #1 results in:

Wait a minute… according to shorten this was supposed to provide similar results to the original but it just made the façade ridiculously unconstructible (albeit much more exciting). So what happened? Well this demonstrates the important concept of prompt dilution.

Prompt Dilution

As you add words to a prompt, they steal the algorithm’s attention from the other words and dilute their strength. When prompts get really long (which is derisively known as “splatter-prompting”) many of the words don’t even meet the threshold to be a token and get completely ignored. Here is an example of what happens when you add or remove excess words. Notice what it does to temper or accentuate the outlandishness of the Art Nouveau styling by simply removing the words “stunning ornamentation”.

Since the only change was removing the word “stunning ornamentation” you would think that would make for a more subdued image but in reality the reverse happens. Art Nouveau now makes up a higher percentage of the prompt so the curves and sinuousness actually ratchet up a notch.

Word Order

Word order also matters as shown in the /shorten analysis. Placing words toward the front of a prompt will give them higher weighting while words at the end may be completely ignored. Here is an example of moving key words up in the prompt to emphasize their importance:

In the first variation, we delete the low-weighted word “award-winning” which shouldn’t have much of an impact, but in reality it both dilutes the prompt and moves Art Nouveau up to the first spot, supercharging the style.

In the second example, “sensibilities” is deleted and “modern” moves up to the top spot. The biological sinew is still there, but the massing and facade take on a more avantgarde composition.

The third example in this and all cases is the Modern Art Nouveau benchmark image for comparison.

Negative Prompts

Negative prompts remove features you don’t want to see. They also help strip away layers of Midjourney’s concept of a style, like the biological filigree look the platform tends to prefer in V5.2. Let’s look at our images and remove some of the less constructible things we see using negative prompts:

Turns out Midjourney sees Art Nouveau as just a blend of craftsman and Victorian style plus a lot of biological motifs (a fair assessment).

Linked Token Reintroduction

As you can see, Midjourney seems to think that terms like “sinuous”, “tendrils”, “filigree”, “lotus pod” and its close relative “trypophobia” are so closely linked with its concept of Art Nouveau that negating them gets rid of our Art Nouveau styling entirely revealing the underlying tokens. So apparently, Midjourney thinks that Art Nouveau is just Craftsman style with biological elements. To fix this overcorrection, you can reintroduce the linked tokens you truly want with more specificity. In this case, let’s use “biophilia” as a more targeted term than the algorithm’s usual overreliance on tendrils and curves. Alternately we can prompt for specific organisms we want it to draw inspiration from like trees, butterflies, and peacocks which are also common in Art Nouveau design.

Specifying Materials

Many of these results have included plaster as their cladding….historically a sensible choice for curved walls. However we can further steer the results away from Midjourney’s material biases and towards more realism by specifying materials like wood, glass, and brick. This helps constrain the results, freeing us from some of the more outlandish curves and pastel colors associated with Art Nouveau plaster buildings (though your carpenter won’t be too happy about these).

Version and Style

Finally, if you are ever struggling to achieve the results you want with words alone, the problem might be in the version or style you are using. Each Midjourney version interprets prompts differently, makes different artistic choices, and has a different aesthetic worth exploring. As of this writing, V5.2 and V6 Alpha are the most recent versions.

Furthermore, Midjourney has two basic styles: Default (a more opinionated, artistic style) and Raw (a more photographic style that interprets prompts more literally). It is up to the designer to determine which model and style works best for their current project. Here are some examples:

Notably, Raw and V6 tend to produce more grounded realistic results, but may not be as artistic or picturesque as V5.2 and Default. Often times, switching to an alternate model or style is the best solution when you hit a dead end in the version and style you’re working in and need a completely different aesthetic that the prompt engineering methods noted above couldn’t achieve.
