Quick answer
What is AI home exterior design, and how do you use it?
AI home exterior design means uploading a photo of the outside of your own house and getting it back with new siding, roof, trim, windows, front door or porch, while the house's shape, rooflines, window positions and camera angle stay the same. On Kenerate AI you do it with Seedream 5.0 Pro — redesign the whole facade in the image studio, or paint over just the siding or just the door with Change Region in Edit Studio. Treat the picture as a concept: the model doesn't measure, so check every window, roofline and step against your real house before you order anything.

Tips
Exterior redesigns that still look like your house
What gives a usable result.
Shoot from across the street, straight on and level, with the whole house, roof and front steps in frame — an overcast day avoids hard shadows.
Move cars and bins out of the driveway first; parked cars get redrawn into odd shapes.
Pin the structure: “keep the same rooflines, number and position of windows, front door, porch, chimney and camera angle”.
Name real materials, not just a style: “white board-and-batten siding, black metal roof, black window frames, natural oak front door”.
Change one element at a time with Change Region when you're choosing between two siding colours or two doors.
If the photo cuts off the roof or a corner, widen it with AI Expand before you redesign.
Count the windows in the result: an extra window, a moved door or a taller roof is the model, not your house.

FAQ
AI Home Exterior Design questions
10 questions
What is AI home exterior design?
Using an AI image model to redesign a photo of the outside of your house — siding, roof, trim, windows, front door, porch and exterior colours — from a text prompt, so you can see a makeover on your own home before you call a contractor. On Kenerate AI you upload the photo to Seedream 5.0 Pro, describe the new exterior and say what must stay, such as the rooflines, windows and door.
Link to this answerCan AI redesign my house exterior from a photo?
Yes, as a picture. Shoot the house straight on from across the street, upload it, describe the new materials and add “keep the same rooflines, windows, front door, porch and camera angle”. The result is a concept image: always compare it with your photo, because an image model can add a window, move the door or change the pitch of the roof without being asked.
Link to this answerWill AI keep the shape of my house?
Usually close, never guaranteed. The model redraws the whole picture, so it can drift: an extra window, a wider porch, a door that moves a few feet, a dormer that wasn't there. Pinning the structure in the prompt helps, and Change Region helps more — paint over only the siding or only the door and the rest of the photo is kept. Nothing it draws is measured, so don't size windows or siding from it.
Link to this answerWhich model is best for AI exterior design?
Seedream 5.0 Pro for most houses: it redesigns the whole facade from your photo and is the default model of Change Region and Magic Eraser in Edit Studio. Use Nano Banana 2.1 (up to 14 reference images) to show a real door, light or stone sample from product photos, and GPT Image 2.5 Sunburst for tightly worded edits. Qwen Image 3.0 is the free-plan option.
Link to this answerCan I change only the siding, the roof or the front door?
Yes. Open the photo in Edit Studio, pick Change Region, paint over just the siding (or just the roof, the trim or the door) and describe the new surface — “white board-and-batten siding, vertical, matte”. Everything you didn't paint stays as it was, so two versions differ in one thing only. Change Region costs 13.5 credits per result on Seedream 5.0 Pro.
Link to this answerIs there a free AI home exterior design tool?
You can start free. A new Kenerate account gets 25 starter credits, and Qwen Image 3.0 is on the free plan: an edit with one photo costs 9.9 credits, fine for quick colour drafts. Seedream 5.0 Pro, the best pick for a full exterior redesign, costs 13.5 credits per image at 1K or 1.5K and 27 at 2K, from one-time credit packs. Downloads have no watermark.
Link to this answerHow much does an AI exterior redesign cost on Kenerate?
It's priced per image in credits, from the app's price code: Seedream 5.0 Pro 13.5 at 1K or 1.5K and 27 at 2K; Nano Banana 2.1 21 at 1K, 31.5 at 2K and 42 at 4K; GPT Image 2.5 Sunburst 11.7 for a medium-quality 1K edit with one photo; Qwen Image 3.0 9.9 with one photo. In Edit Studio, Change Region on Seedream 5.0 Pro is 13.5 per result. No subscription is needed.
Link to this answerCan AI pick an exterior paint colour for my house?
It can show you colours on your own house, not tell you which paint to buy. Screens and AI both shift colours, so use the picture to narrow it to two or three, then test real samples outside. Benjamin Moore, for example, says its liquid samples are for interior use only and recommends painting a white foam board for exteriors. For exact colours and hex codes, see the AI paint color visualizer.
Link to this answerCan I use an AI exterior picture in a real estate listing?
Not as a photo of the house as it is. MLS rules such as California's CRMLS bar altering real property features, and NorthstarMLS's proposed guidelines name roofing, siding, doors and windows. Use exterior redesigns to plan your own remodel or to show a buyer a clearly labelled idea next to the real photo — and see AI real estate photo editing for the edits listings allow.
Link to this answerIs an AI exterior design as good as an architect or designer?
No — it is a fast way to explore materials and colours, not a design service. It doesn't measure the house, check structure, drainage, HOA rules, permits or historic-district limits, or size windows and siding. Use the images to decide what you like, then take them to a designer or contractor. On a US house built before 1978, paid work that disturbs paint must follow the EPA's lead-safe rules.

Which Kenerate model should you use for a house exterior?
All four take your house photo as a reference and edit it rather than drawing a new house. Credits are per image, read from the app's price code on 22 October 2026.
- Seedream 5.0 Pro — whole-facade redesigns from one photo, and the default model of Change Region and Magic Eraser in Edit Studio. Up to 10 images. 13.5 credits at 1K or 1.5K, 27 at 2K; Change Region is 13.5 per result.
- Nano Banana 2.1 — when the real products matter: the front door you're looking at, a light fixture, a stone or siding sample as extra references. Up to 14 images, 1K to 4K. 21 credits at 1K, 31.5 at 2K, 42 at 4K.
- GPT Image 2.5 Sunburst — careful, literal edits (“replace only the garage door, keep everything else”). Up to 16 images. 11.7 credits for a medium-quality 1K edit with one photo, plus 4.5 per extra image.
- Qwen Image 3.0 — on the free plan; the default AI Edit model. Up to 3 images. 9.9 credits with one photo. Good for quick colour drafts; it isn't offered on Change Region.
Exterior styles and the words that work
A style word alone gives a generic house. Name the siding, the roof, the trim, the windows and the door:
- Modern farmhouse — “white board-and-batten siding, black standing-seam metal roof, black window frames, natural wood front door, black gooseneck lights”.
- Craftsman — “sage green horizontal lap siding, cream trim, tapered porch columns on stone bases, stained wood door with glass panes”.
- Coastal — “light grey cedar shingle siding, white trim, white porch railings, navy front door, brushed nickel lanterns”.
- Modern — “smooth white render, vertical charcoal fibre-cement panels, slim black window frames, flat canopy over the door”.
- Colonial — “white clapboard siding, black shutters, dark grey asphalt shingle roof, red front door with a brass knocker”.
- Dark and moody — “charcoal siding, matching charcoal trim, black roof, warm cedar soffits and door”.
- Brick refresh — “keep the brick, limewash it soft white, black windows, oak door” (painting or limewashing real brick is hard to undo — sample it first).
Siding, roof, windows, door: change one element at a time
Most exterior decisions are between two options for one element — white or green siding, black or bronze windows, a wood or a painted door. A full redesign changes everything at once, so you can't tell which change you like. In Edit Studio, Change Region lets you paint over only the siding (or only the roof, the trim or the door) and describe the new material; the rest of the photo stays untouched.
ByteDance describes colour and material swaps that keep the scene's perspective as one of Seedream 5.0 Pro's strengths, and also notes that pixel-level consistency can still improve — so look closely where siding meets trim, window frames and the roof edge.
Will AI keep my house's shape?
It tries to, but an image model never measures. It redraws the whole picture and can quietly change the structure. Check every result against your photo for:
- Windows: the same number, the same size and the same positions — models like to add or line them up.
- Rooflines: the same pitch, ridge height, overhangs and dormers; no new gables.
- Door and steps: the front door in the same place, the same number of steps, the same porch depth.
- Garage and driveway: the same width and position.
- What you can't see: siding sized to real walls, gutters, flashing and structure are not in the picture at all. Use it to choose a look, not to measure or order materials.
The prompt that keeps it your house
Moving windows, doors and rooflines is where exterior budgets go. Pin them in every prompt:
- “Redesign the exterior of this house in [style].”
- “Siding: [material + colour + direction]. Roof: [material + colour]. Trim: [colour]. Windows: [frame colour]. Front door: [style + colour].”
- “Porch and lighting: [columns, railings, lights]. Landscaping: keep as it is.”
- “Keep the same rooflines, number and position of windows, front door, porch, chimney, driveway, sky and camera angle.”
From picture to real exterior
An AI exterior is a mood board for your own house. Once you like a direction, get real samples of the siding, roof and paint and look at them outside, on the house, at different times of day — Benjamin Moore recommends a white foam board for exterior paint samples and testing from morning to evening, and notes that on-screen colours may differ from the real paint.
Check your HOA rules and whether your town needs a permit for new siding, roofing or windows — historic districts often have their own review. In the US, if the house was built before 1978, contractors paid to disturb painted surfaces must be EPA-certified for lead-safe work. For the yard in front of the house, use the AI garden design generator; for a new build from a sketch, the AI architecture generator.
