Floor Plan Creator

Create a floor plan by describing it, then shape it by chat. Every version is measured: the dimension strings, room sizes and areas on the drawing come from the same geometry, and a checker tells you what is off before you share it.

Opens Plan Chat with your brief filled in. Nothing is sent until you press send there.

Paid plans from $29/month for 50 generations ($14.50 the first month, $19/month billed annually). One floor plan = one generation. No free tier. Same account and credits in Plan Chat. Have a sketch or a photo of a plan instead? Upload it below.

A plan created from one sentence, with its dimension strings

Drafted by Plan Chat from the one-line brief below, not retouched. The dimension strings, room sizes and areas are read from the plan geometry, so they agree with each other. The checker report under the plan is the engine's own, unedited: it says where the plan falls short of the brief instead of hiding it.

Brief: “1,500 sq ft single-story house, 3 bedrooms, 2 baths, open kitchen, dining and living, laundry, 2-car garage.”

single-storey 3-bedroom floor plan, about 1,511 sq ft, generated by AI from the brief "1,500 sq ft single-story house, 3 bedrooms, 2 baths, open kitchen, dining and living, laundry, 2-car garage." with labeled rooms, room sizes, doors, windows and overall dimensions; dimension strings 53'-6" by 36'-9" overall

Create first, then refine in plain words

Classic floor plan creators make you draw: drag a wall, snap a door, type a dimension, repeat. That is precise, but slow, and most people stop before the plan is finished. A text-only AI is fast but forgets the house the moment you ask for a change, so every edit gives you a different plan.

This floor plan creator sits between the two. You create the first version from a brief, then edit it like you would brief a draftsperson: one sentence per change. The engine changes the rooms you name and keeps the others, so a bigger kitchen does not move the bedrooms to the other side. Several plans in the gallery below were revised that way; their pages say what each revision changed (for example, “gives the bonus room real walls and a window, and moves the walk-in closet back to the primary bedroom”).

Numbers that agree with each other

Look at the plan above. The dimension chain along each wall adds up to the overall dimension (within an inch of rounding), each room's size in the table matches the label on the drawing, and the room areas add up to the living area. That is not a design choice, it is how the plan is made: rooms are closed shapes with real sizes, and walls, dimensions and labels are derived from them. The same numbers go into the DXF, so when you open it in AutoCAD the walls are where the drawing says they are.

Need a quick concept drawing instead? The AI floor plan generator turns a sketch, photo or short text into a clean plan image in 30 seconds. For measured plans without the editing focus, see the floor plan generator.

Make a floor plan in 4 steps

  1. 1

    Start from a brief

    Write the program in the box above, or copy a brief from one of the plans on this page and change it.

  2. 2

    Create the first version

    Plan Chat draws a measured plan with dimension strings, room sizes and areas, plus a checker report.

  3. 3

    Edit by chat

    Send one change at a time: "bedroom 3 to 11 x 12 ft", "swap office and dining", "add a mudroom between garage and kitchen". The rest of the house stays where it is.

  4. 4

    Keep the version you like

    Export PDF, DXF and IFC for that version, or ask for an exterior render and a 3D model.

Already have a sketch or an old plan?

Upload it here and get a clean, labeled plan drawing in about 30 seconds (PNG/JPG with a DXF beta trace). It keeps your layout but does not measure; for real sizes, read them off the drawing into the Plan Chat brief above. More on sketch to floor plan.

Plans created and then edited by chat

Each plan below was drafted by our AI from the one-line brief under it, not retouched. These were made in Plan Chat (same account and credits), which draws measured plans and exports PDF and DXF. Open a plan to see room sizes and download the files.

Frequently asked questions

Can I change the plan after it is drawn?

Yes, by chat: "make bedroom 2 12 x 11 ft", "move the laundry next to the garage", "add a covered porch". Plan Chat changes that part and keeps the rest of the house, re-runs the checker, and you export PDF, DXF and IFC for the version you keep.

Do I have to draw anything?

No. This floor plan creator works from words: the rooms, sizes and what goes next to what. There is no wall tool to learn. If you already have a sketch, upload it in the image tool lower on this page for a clean drawing, then use its sizes in the brief.

How do I know the dimensions are right?

Plan Chat builds the plan as geometry first: each room is a closed rectangle with a real size, walls are generated from the room boundaries, and every dimension string, room size and area on the drawing is read from that geometry. Then a checker runs on every version: rooms reachable from the front door, halls at least 36 in wide, bedrooms with egress windows, rooms close to the size you asked for. Its warnings are shown, not hidden.

Is there a free floor plan generator here?

No. There is no free tier and no trial. Plans start at $29/month ($14.50 the first month), the same credits work on this site and in Plan Chat, and you can cancel anytime. What the money buys: measured plans whose dimensions agree with each other, a checker report on every plan, PDF, DXF and IFC files, and changes by chat. Free tools are fine for a picture of a plan; they are not built to keep the numbers right.

Can it create two-storey plans?

Yes. Describe what goes downstairs and what goes upstairs. You get one plan per level with its own dimension strings and a DXF per level.

Can I use it for an office or a shop?

Yes: list the rooms with head counts or sizes. The small office plan in the gallery was created from "Small office for 20 people: reception, open office, 3 meeting rooms, 2 private offices, kitchen, 2 restrooms, storage, about 3,200 sq ft."
