Three storey house design
Three Storey House Design: See the House on Your Plot
People searching for a three storey (or 3 story) house design are usually building on a narrow or expensive plot, where going up is the only way to fit parking, living rooms and bedrooms. This AI three storey house design tool turns a photo of the plot, a sketch or a clay model into a photo-like front view of the finished house in the same view; then you describe the walls, the balconies, the louvres and the roof terrace in a sentence. The result is an idea picture of the outside. It is not a floor plan, a structural design or a quote.

Why build three storeys, and what people look for
Design sites such as DesignsCAD and Mytour, and projects published on Dezeen, show three-storey houses mostly on narrow or costly plots, where building up is the way to get more rooms. Common features:
- Car parking or a garage on the ground floor.
- Balconies with glass or metal railings on the upper floors.
- A roof terrace with a railing, shade or plants.
- Louvres or screens for privacy and sun.
- Two or three materials stacked floor by floor.
How to try a three storey house design with ArchitecturesAI
- In the editor above, the mode is Render Architecture, the type is Residential and the style is Modern. This mode has no prompt box: you start from an image.
- Under Select Image, upload a JPG or PNG: a daylight photo of the plot taken from the street, a photo of an existing house, or a sketch, a clay model or a screenshot from your 3D software.
- Click Generate. Free accounts can only use Low quality (Medium and High are marked PRO). Sign in with Google or email when asked.
- To steer the result, click Edit Image on it (the box is called Edit Instructions) or use Custom Action, and describe the materials floor by floor, the balconies, the parking, the louvres and the roof terrace and what must stay the same. Each edit is another render and uses credits. Run it a few times, since every result differs.
- The three examples below ran directly on our image model with the written instructions shown. They did not go through the editor above, so your own results will differ.
A three-storey house on a narrow plot
Narrow plots between existing buildings are the most common starting point. This example kept the neighbours and the power lines, and placed the house further back than you might expect.

After: a modern three-storey house on a narrow plot
From a sketch or a 3D model to a photo-like front view
If you already have a sketch or a simple 3D model, the render keeps the three floors and adds the materials. Both examples changed some details, listed in the captions.

Before: line sketch of a three-storey house (AI-drawn stand-in for a hand sketch)

After: sketch turned into stone, wood and glass

Before: clay model of a three-storey house (AI-drawn stand-in for a 3D model)

After: clay model turned into brick and render
What the AI keeps and what it may change
- Usually kept: the camera angle, the neighbours, the number of floors and the shape of a sketch or model.
- Often different from what you asked: where the house sits on a plot, gates, which floor gets which material, and recessed details.
- Often added without being asked: railings, walls, gates and trees.
- Never produced: floor plans, structure, plot setbacks, cost estimates or approval drawings.
Two storeys instead?
Our two storey house design page has the same kinds of examples for two floors, and the second story addition page starts from a photo of an existing house.
Free tier and plans
You need a free account to render. New accounts get 2 free renders, and free renders carry a watermark. In India this site does not include free renders, so a paid plan is needed there. Weekly, monthly and yearly plans for more renders without the watermark are on the pricing page.
The plot, the sketch and the clay model on this page are AI-drawn stand-ins, not real. Each example was run directly on the model, not through the tool above.
Frequently asked questions
Can AI design a three storey house?
It can draw exterior idea pictures: a three-storey house on a photo of your plot, or a photo-like view of your sketch or 3D model. It does not draw floor plans or check plot rules.
Is it "three storey" or "3 story"?
Both mean the same: "storey" is the British and Commonwealth spelling, "story" the American one. The tool works the same either way.
Is there a text box in the editor?
The prompt box exists only in Architecture Generator mode. The editor above opens in Render Architecture, where you upload an image and change the result with Edit Image (Edit Instructions) or Custom Action.
Is it free to try?
Yes. After you sign in, a new account gets 2 free renders with a watermark, in Low quality. In India this site does not include free renders. Paid weekly, monthly and yearly plans are listed on the pricing page.
