Floor Plan Maker

Make a floor plan your builder can price from: real room sizes, dimension strings that add up, doors and windows where they belong, and a PDF and DXF to hand over. Describe the house below, or upload a sketch or old plan further down.

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 you can hand to a builder: every size on the drawing

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: “Detached 2 bedroom ADU, 1 bath, open kitchen and living, laundry closet, covered porch, about 800 sq ft.”

single-storey 2-bedroom floor plan, about 796 sq ft, generated by AI from the brief "Detached 2 bedroom ADU, 1 bath, open kitchen and living, laundry closet, covered porch, about 800 sq ft." with labeled rooms, room sizes, doors, windows and overall dimensions; dimension strings 35'-9" by 24'-7" overall
Overall 35'-9" × 24'-7" · 796 sq ft living

Made for people who are not drafters

Most people who need a floor plan are not designers. They are adding an ADU, getting a builder's quote, applying for a permit consultation, selling or renting a home, or settling an argument about whether a fourth bedroom fits. They need a plan that is clear and right, and they do not want to learn a CAD program to get it.

This floor plan maker takes the information you already have, in words, and turns it into a measured plan. The drawing shows the overall dimensions on every side, a dimension chain along each wall, room names with sizes and areas, door swings and windows. The plan above came from a single sentence; the table next to it shows that the room areas add up and the checker found nothing to flag.

Sketch, photo or words: which route

If the house exists on paper, upload the sketch or the old plan in the image tool on this page: you get a clean drawing in 30 seconds that keeps your layout (see floor plan from image). If you need real sizes, describe it in the box at the top and let Plan Chat measure it out. For designers who want to iterate on many versions, the floor plan creator page shows the edit-by-chat workflow; for AutoCAD, the AutoCAD floor plan generator page lists the DXF details.

Make a floor plan in 4 steps

  1. 1

    Measure or decide the sizes

    For an existing house, measure the outside walls and the main rooms with a tape. For a new one, decide bedrooms, baths and roughly how big.

  2. 2

    Write it in the box above

    "Detached 2 bedroom ADU, 1 bath, open kitchen and living, laundry closet, covered porch, about 800 sq ft" is enough to start.

  3. 3

    Check the plan against reality

    Compare the dimension strings with your tape measurements and the checker report with what you need. Correct anything by chat.

  4. 4

    Hand it over

    Send the PDF to your builder or lender, the DXF to a designer, or use the images in a listing.

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.

Frequently asked questions

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 I make a floor plan of my existing house?

Yes. Measure the outside walls and the main rooms, write them into the brief ("ground floor 40 x 28 ft: living 16 x 14 ft at the front, kitchen 12 x 11 ft behind it, two bedrooms 11 x 12 ft on the left") and correct the plan by chat until it matches. If you have an old drawing, upload it in the image tool on this page first for a clean copy.

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 it good enough for my builder or contractor?

It is a clear, measured plan they can price from and talk about, with a PDF and a DXF their designer can open. It is not a permit set: for permits, a designer or architect turns it into drawings that meet your local code.

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.

Can I use the plan in a real estate listing?

Yes. Listing floor plans are usually marked as approximate; say so unless you measured the home. The PNG and PDF downloads are ready for listing sites and brochures.
