AI house design for home designers in India
Describe the house.
Describe the house.
Let AI draw it.
Connect Claude or ChatGPT to OctBuild and design by conversation. Ask for a 2BHK on a 30 × 40 plot and watch the walls, doors, stairs and rooms appear in 2D and 3D. Then refine it by hand, compare options, and show your client the same day.
Try it now with one house plan, kept in your browser, no account needed. Saved projects, your team and AI design come with an account. We're adding practices by invitation.

Describe the house
Plot size, facing, how many bedrooms, where the stairs go, what the client asked for. Change your mind as often as you like.

Refine and share
Every AI step lands in your open plan and can be undone. Adjust by hand, save a version, and share the option with your team or client.
Things to ask
- “A 2BHK on a 30 × 40 ft plot, east facing, with parking in front.”
- “Make the kitchen bigger and move the pooja room to the north-east.”
- “Draw Option B as a duplex, with the bedrooms upstairs.”
- “Add a compound wall with a sliding gate, and a sit-out by the garden.”
- “Show me the house in 3D from the street, then save it as version 2.”
-
You stay in control
Each change is one undoable step, and the AI can only do what your role allows. Nothing it draws is final until you say so.
-
It looks at its own work
The AI can view the plan and the 3D model as pictures, so it checks what it drew before telling you it’s done.
Start Option B for the Sharma house: a 2BHK on the 30 × 40 ft plot, main door facing east.
→ create_proposal Option B
→ set_site 30 × 40 ft, facing east
→ add_room Living · Kitchen · Bedroom 1 · Bedroom 2
→ add_opening main door, east wall
→ view_plan 3D
Option B is drawn: living room at the front with the main door on the east, kitchen behind it, and both bedrooms along the north side. It’s open in your planner. Shall I save it as version 1?
Yes, and make bedroom 1 a little wider.
Draw
Or draw it yourself. Same plan, same tools.
Everything the AI can do, you can do by hand, and the two mix freely: let it lay out the rooms, then drag a wall or swap a window yourself.
-
Walls, by click or by number
Click corner to corner, or type 4500, 4.5m or 12'6" and press Enter. Rooms are named and measured as they close.
-
Doors, windows, gates and stairs
Pick a style and size and drop it on a wall. Doors swing the way you point, and open on a click in 3D.
-
Roofs, finishes and furniture
Roof shapes, stone and brick finishes, your own wall textures, furniture and parked cars, so a client sees a home and not a diagram.
-
The real plot, the real sun
Put the plot on the map to see the street around it and where the sun falls through the day.
Built the way houses are built here
From the footings up.
OctBuild follows how an RCC-framed house goes up in India, so the drawing carries through from the site to the finishes.
Foundation plan
Footings, pits and plinth beams on their own sheet beside the floor plan, and a see-through ground in 3D to check them.
Floors and levels
Ground, first and terrace on one plan, with pillars, plinth and stairs that line up between them.
A guide to how it's built
The Learn guide walks through every part of a house in the order it's built, with typical sizes, for you and for your clients.

For your practice
Every client, every option, every version.
Keep each house as a project, with as many design options as the client wants to compare. Nothing is lost and nobody overwrites anybody.
-
Saved as you draw, versions when it matters
Every change saves itself. Keep a numbered version before you send it to a client, and go back to any one later.
-
Your whole team, with the right rights
Admins, members and viewers. Keep a project private, or share it with just the people working on it.
-
Open in two places, never out of step
When someone else saves, the open plan updates. If two people change it at once, OctBuild says so instead of losing either change.
