What it is
What is an AI house plan generator?
An AI house plan generator turns what you want in a home into a floor plan. Instead of drawing every wall, you describe the house: its outline, its size and the rooms inside it. The AI arranges those rooms into a layout you can walk through.
Floorra's AI house plan generator works like an architect's first sketch. It reads your outline and every room you chose, writes a short brief (public rooms toward the street, bedrooms in a quiet zone, the garage beside the kitchen, rooms that belong together) and then draws layouts that follow it. Each plan is checked before you see it: every room reachable, every bedroom with a window, room sizes that make sense.
You are never handed a fixed picture. Every AI floor plan opens in the full editor, so you can move a wall, rename a room, add doors and windows, and see the change in 3D straight away.
How it works
Generate a floor plan with AI in four steps
No drawing skills needed. If you can list the rooms you want, you can design a house.
Step 1 Step 2 Add the rooms you need
Choose from 32 room types in small, medium or large, or customize a room's size by dragging its walls. Floorra shows at once whether your rooms fit the house.
Step 3 Tell the AI architect your wish
Optional: write it in plain words, like "office next to the living room" or "primary bedroom at the back". The wish becomes requirements the plan has to meet.
Step 4 Pick one of three plans
Compare three complete designs side by side, see each one on the plan and in 3D, then keep editing the one you like best.
What the AI does
More than a room arranger
The AI architect plans the whole house, then fills in the details a first layout needs.
Zones like a real home
Living, kitchen and dining toward the entrance, bedrooms kept quiet, closets and bathrooms beside the bedrooms they serve, the garage by the kitchen.
Hallways only where needed
When bedrooms would open onto each other, it adds a hallway so every bedroom has its own door, and it tells you when it did. Nothing else is added to your rooms.
Every room checked
Each plan passes architectural checks: rooms reachable, windows in every bedroom, sensible sizes, no leftover empty space. Anything it could not meet is listed in plain words.
Doors, windows and finishes
The chosen plan comes with suggested doors, windows and open passages, plus wall and floor finishes for each room, all of which you can change.
Three options, side by side
See three designs as small plans with their checks, put any of them on the big plan, and switch between them at any time while you work.
Your wish, followed
Say which rooms should be together, apart, at the front or at the back. The report shows which wishes were met and which the outline could not allow.
Who it is for
An AI home design tool for real projects
Use the AI house plan generator to explore a home before you talk to a builder or an architect. It turns a room list into something concrete you can look at, change and share.
- Homeowners planning a new single-storey house
- Families comparing layouts before buying a plot
- First-time home designers who have never drawn a plan
- Designers and builders sketching an early concept for a client
Good to know
- The AI architect designs single-storey homes today. Two- and three-storey houses are coming soon.
- Plans are concepts for exploring and discussing a home, not construction or permit drawings.
- You need a free account to run the AI architect; you can explore the editor without one.
What is an AI house plan generator?
An AI house plan generator is a tool that turns your requirements, such as the house outline, its size and a list of rooms, into a complete floor plan. Floorra's generator plans the whole house like an architect's first sketch and shows the result in 2D and 3D.
Is there a free AI house plan generator?
Yes. Floorra's AI architect is free during the preview. Create a free account, choose your house shape and rooms, and generate three floor plans. There is nothing to download or install.
How does the AI floor plan generator work?
It reads your outline and every room you chose, writes a design brief (zones, entrance, garage side and which rooms belong together), then draws layouts that follow the brief. Each plan is checked for reachable rooms, bedroom windows and sensible sizes before you see it.
What should I write in my wish?
Use plain words about where rooms go: "office next to the living room", "primary bedroom at the back", "laundry close to the bedrooms", "garage opening to the side". The AI turns the wish into requirements and reports which ones it met.
Can I edit the AI floor plan afterwards?
Yes. Every generated plan opens in the full editor. Drag rooms and walls, resize the house, rename rooms, add or move doors and windows, change materials and add furniture. You can also switch back to another of the three designs.
Can I see the AI house plan in 3D?
Yes. Every design has a live 3D model you can orbit and zoom, with an exterior view and a furnished cutaway. The 2D plan and the 3D model are built from the same design, so they always match.
Can I download the house plan?
Yes. In the review step you can download a PDF drawing set, DXF CAD drawings, a GLB 3D model, an IFC building model and the editable project data.
Does an AI house plan generator replace an architect?
No. It is a fast way to explore and communicate ideas. A qualified architect or designer still needs to develop the structure, services, code compliance and construction drawings before anything is built.
Can the AI design a two-storey house?
Not yet. The AI architect currently designs single-storey homes. Two- and three-storey houses are coming soon.
How accurate are AI-generated floor plans?
Rooms are sized in real feet and checked against usable minimums, and the plan is drawn to scale. Treat it as an accurate concept: measure your plot and confirm the details with a professional before building.
Do I need design experience?
No. If you can list the rooms your household needs, you can generate a house plan. Every step explains itself, and the plan stays editable, so there is no wrong first choice.
