Facade design software falls into five groups: BIM and modeling tools for the geometry, performance tools for energy and daylight, real-time engines for renders from the model, manufacturer visualizers for real products, and AI image tools for fast pictures of options. This guide sorts them by job, as of October 2026, and gives a six-step way to compare facade options on one view before a client review.
The short version of the method: keep the building and the view fixed, change one thing at a time and show two or three options side by side. An image tool such as ArchiVinci generates each option in seconds from a photo, a sketch or a model view; drawings, product samples and local rules still decide what gets built.
Facade Design Software, Visualizers and Image Tools: What Each Does
No single program covers everything a facade needs, so most offices combine two or three kinds. This table sorts them by the job they do, with examples as of October 2026:
Kind of software | What it is for | Examples | Good for comparing options? |
|---|---|---|---|
BIM and 3D modeling | The building's geometry, openings, curtain walls and drawings | Revit, Archicad, SketchUp, Rhino with Grasshopper | Yes, but every option has to be modeled |
Facade performance | Figures for heat, daylight, shading and solar gain | FenestraPro for Revit and Autodesk Forma | For energy, not for looks |
Real-time render engines | Renders and walkthroughs straight from the model | Enscape, Twinmotion, Lumion, D5 Render | Yes, once each option is modeled |
Manufacturer configurators and visualizers | A maker's real products and colors on a sample building or a photo | Yes, within one maker's range | |
AI image tools | New photorealistic pictures of options from a photo, a sketch or a model view | ArchiVinci (Exterior and Edit modules), Chaos Veras inside BIM tools | Yes, and fast; pictures, not measured drawings |
BIM and real-time engines are where the chosen facade is drawn, documented and rendered for good, but each option has to be modeled first. Our guide to real-time rendering explains how those engines work, Revit rendering shows how a Revit view becomes a photorealistic image in ArchiVinci, and ArchiVinci vs Revit, ArchiVinci vs SketchUp and ArchiVinci vs Enscape compare the two approaches.
Manufacturer visualizers show real products, but only their own. Image tools sit at the fast end: in ArchiVinci you upload a photo, a sketch or a model view to the Exterior module and get a new photorealistic image of the facade in seconds, and the Edit module changes only the area you mark. Neither kind gives measured drawings.
How to Choose the Right Facade Software
Start from the question the client or the team has to answer:
What exactly gets built? Model it in BIM: drawings, quantities and details come from there.
How does it perform? Run a performance tool on the model.
Which product, which color? Use the manufacturer's visualizer and ask for physical samples.
Which direction do we take? Show two or three options on one view with an image tool, then model only the chosen one.

How to Compare Facade Options in 6 Steps
These steps work with any of the tools above, so that the options differ only where the client has to decide; the ArchiVinci parts show how each step runs in an image tool.
1. Fix What Must Not Change
Before you generate anything, write down what stays: the massing, the openings, the roofline, the budget and any local rules on materials or colors. These limits make the options comparable and keep you from showing the client a facade that cannot be built. Put the most important ones into every prompt, for example "keep the windows and roofline": on ArchiVinci's default engine that is an instruction the model is asked to follow, not a lock, so check every result against the original.
2. Use the Same View for Every Option
Pick one view the client knows, usually an eye-level photo of the street front or an exported view of the model, and use it for every option. ArchiVinci has no viewpoint control, so each view is its own upload: a JPG, PNG or WebP file of up to 5 MB, such as a photo, a hand sketch or a screenshot from Revit, SketchUp or another 3D tool. The app does not open model files, so export the view first; our page on 3D model to render shows that route.
On an existing building, start from a photo of today's facade; our facade renovation guide covers the renovation project itself.
3. Test Whole Directions on a Photo, Sketch or Model View
Now try two or three complete directions on that view. In ArchiVinci's AI facade design tool, the Exterior module, you upload the view, keep the default render engine or pick another, add objects such as a car, trees or people if the scene needs them, describe the facade in the optional prompt and choose one of six lighting buttons: Daylight, Afternoon, Twilight, Golden hour, Warm light or Backlit. Click Generate and a new image that follows your upload comes back in seconds; with a plan you can ask for up to four images a run.
Short prompts work best, and above 200 characters the app shows a warning. Name the cladding, the colors and the roof in words, because there is no style or building-type menu. For a sketch or a model view of a new build, a prompt can describe the whole house:
"Contemporary house exterior with natural wood cladding, floor-to-ceiling glass, warm interior lighting, clean modern lines, and strong indoor-outdoor connection to the forest."
For a photo of an existing house, say what stays as well:
"Keep the windows and roofline. Dark timber cladding on the upper floor, light gray brick below, black window frames."
Every run draws a new image, so generate each direction twice before you judge it and change only the prompt between directions. For a photorealistic picture of a sketch or a model view without a facade change, see AI rendering. Words for cladding and style are in our house facade ideas and exterior styles, and prompt structure in our best practices for crafting AI prompts for architectural renders.
4. Change One Material and Keep the Rest
When the client likes a direction but asks for another brick or a darker timber, do not generate the whole facade again. ArchiVinci's Edit module, which we call ArchiGPT, redraws only the area you mark: select the wall with the brush or the lasso, then apply one of the 103 materials in 15 categories of the texture library or your own sample picture, or type the change in the prompt, which Edit always needs.
To borrow a look for the whole facade, leave the area unmarked, put a material board or a facade photo under "Upload object (optional)" and say in the prompt what to take from it. The model is asked to work the reference in and keep the shape you name; the whole picture is redrawn, so check the details.
Example from our style transfer page, made in the Edit module on the default engine with no area marked, a material board as the reference picture and the prompt "Restyle the house with the materials of the second image: brick, dark timber and black metal. Keep the shape of the house". Left: the uploaded render. Right: the result.
Change one facade material and keep the rest Upload a photo or a render of the building, mark a wall in the Edit module and apply a material from the texture library or your own sample: only the marked area is redrawn. A new account starts with 3 free credits. |
5. Compare the Same Facade in Different Light
Light changes how a material reads. Keep the same upload and prompt in Exterior and change only the lighting button, for example Golden hour and then Twilight. There is no night button: Twilight gives dusk with the lights on, and a full night scene is a typed request in the Edit module. Each run is a new image, so check that the materials stayed the same. More on light in our guide to AI lighting models.
6. Present Two or Three Options Side by Side
Put the options on one board: the same view, a label under each with its materials, and one line on what is still open, such as the exact product. Many architects find these images client-ready; with a plan you can run a direction again as often as needed and upscale a result to 4096 px on the long side for print. Client work and marketing need an active plan, which includes the commercial use rights; plans are on the pricing page. Once the client has chosen, take that direction into the model and the drawings and check it against product samples and the local rules.
No Drawings Yet? Start From a Plan and a Massing View
For a new build there is often no model or photo to compare options on. Floor Plan Maker, ArchiVinci's plan editor for desktop browsers, gives you one: draw the plan, upload a plan image or PDF for AI to rebuild as an editable plan, or generate a furnished first layout from a short brief. Its massing view, with a sun direction control, shows the volume, and an exterior 3D scene can be rendered with ArchiVinci's engines and used as the view for steps 3 to 6. Drawing, the 3D view and exports (DXF, GLB, OBJ and more) are free; AI plan reading costs 1 credit on a free account and is refunded if the conversion fails, and renders use the normal render credits.
What a Facade Image Cannot Tell You
A facade image is for choosing a direction with the client. It complements drawings and checks; it does not replace them. Before an option goes further, check:
Dimensions: an image has no measurements; sizes, areas and joint layouts come from the drawings.
Structure and fixing: whether a cladding can be carried, fixed and detailed is a question for the engineer and the supplier.
Energy and daylight: heat loss, daylight and solar gain need a performance tool such as FenestraPro, not a picture.
The real product: a brick in an image is not a product, so match it in a manufacturer's visualizer and with physical samples.
Permission: cladding, color and window changes can need approval, as the question on permission below explains.

Frequently Asked Questions
Which tools help compare facade options before a client review?
Image tools are the quickest way to show whole directions on one view: ArchiVinci's Exterior module generates each option in seconds from a photo, a sketch or a model view, and its Edit module changes one material and keeps the rest; Chaos Veras runs material and color studies inside BIM tools. Manufacturers' visualizers show their real products, and the BIM model takes the chosen option forward.
Is there free facade design software?
Yes, for parts of the job, as of October 2026. Pfleiderer's facade design tool is free online (an account saves your designs), Hover's siding visualizer is free, and AZEK's visualizer can be used without an account. On ArchiVinci a new account starts with 3 free credits. In Floor Plan Maker, our free floor plan creator, drawing, the 3D view and exports cost nothing.
Can I upload a photo of a building and change the facade for free?
Yes. Manufacturers' visualizers such as Hover and AZEK put their own products on a photo of your home at no cost. To try any cladding, color or style you can describe, upload the photo to ArchiVinci's Exterior module and describe the change in a sentence: the 3 free credits of a new account give you three images on the default engine. Commercial use of the results needs an active plan.
Will the new image keep my building's shape?
Mostly, but check it. On ArchiVinci's default engine the model is asked to keep the perspective and the geometry of your upload, and naming what stays in the prompt helps. That is an instruction, not a lock: details such as window bars, railings or the roof edge can change, and every run is a new image. Treat the result as a picture for choosing a direction; it should complement, not replace, technical drawings.
Does it work with any type of building?
Yes. ArchiVinci has no building-type menu and needs none: upload a photo, a sketch or a model view of a house, an apartment block, an office or a shop and say in the prompt what it is and what should change. For shop fronts, see our page on AI shop design.
Who owns the images, and can I use them commercially?
These are two questions. On copyright, the US Copyright Office said in January 2025 that AI outputs are protected only where a human author has determined sufficient expressive elements, and that prompts alone are not enough (Copyright Office, January 2025); the rules differ by country. On use, each platform sets its own terms: on ArchiVinci, client work, marketing and any other commercial use need an active plan, which includes the commercial use rights. Check a tool's terms before you send its images to a client.
Do I need a powerful computer or special software?
Not for ArchiVinci. It runs in the browser and generates each image online, not on your computer, so a stable internet connection and a browser on a laptop, tablet or phone are enough; Floor Plan Maker needs a desktop browser. Desktop BIM software and real-time engines run on your computer and have their own hardware requirements.
Do I need permission to change a facade?
It depends on where the building is and what changes. In England, for example, painting external walls needs no planning permission, while new cladding needs it in a Conservation Area, a National Park, an Area of Outstanding Natural Beauty or the Broads, and elsewhere does not if the materials look similar; listed buildings need listed building consent (Planning Portal, October 2026). Elsewhere, check the local planning and building rules, any historic district rules and, in the US, your homeowners association before you show the client an option that may not be approved.
