AI · Works on your own plan
Upload the floor plan you already have — a builder's drawing, an old paper plan, a photo of a sketch — and say what is changing. FloorDrafter redraws the plan with that change and leaves the rest of the house where it was. That is a floor plan for renovation in a minute or two, one version at a time, and the first one needs no account.

A real run from this page: the same builder's plan, one sentence asking for the kitchen–dining wall to go. Yours appears here in a minute or two.
A renovation floor plan is the plan of your home with the change you are considering drawn into it — the as-built and the proposed, as a builder would call them: the same walls, doors, windows and room names as today, plus the wall you want out or the room you want to use differently. It is what you put in front of a builder, an architect or your family to argue over, not a drawing for planning or building control.
A builder's handover plan, the estate-agent plan from when you bought, a council or archive copy, an old paper plan, a screenshot from a listing, or a phone photo of a sketch. Photograph the sheet square on and let the paper fill the frame: a desk edge or a table in the shot tends to get drawn in as if it were part of the house.
Working from an old or faint drawing? Redraw it clean first
Every change on this page starts from the same builder's drawing, and each one started from something that drawing was making worse. Here is what we were looking at.
A solid wall between them with one doorway through it. Whoever is cooking is in a different room from everyone at the table. That is the wall in the first example below.
And the plan has two bedrooms. Trading the indoor parking for a third bedroom is the kind of change that is worth more than the parking to most households. That is the second.
Room names and dimension figures tell you a bedroom is 12 ft by 11 ft. They do not tell you whether a double bed and a wardrobe both fit along its short wall. That is the third.
None of the three needs a survey or a new drawing from scratch. Each one is a sentence about a plan that already exists.
Examples
Each pair below is the same builder's drawing before, and what came back after. Only the sentence changed. These are real runs from this page in September 2026, not mock-ups, and the table further down says what came back imperfect as well as what worked.
What came back, depending on what was asked
Three steps, a minute or two each. The third one is the one people skip and then regret.
A builder's drawing, an estate-agent plan, a council copy, an old paper plan or a phone photo of a sketch. Shoot it square on and let the paper fill the frame.
Name the wall or the room that changes, then add that every other room, door, window and dimension stays where it is. One change per run.
The result appears beside the plan you uploaded. Walk the rooms you did not mention and check they came back the same, then download the PNG, export a DXF, or carry on in the editor.
The sentence does most of the work, and it has two halves. Name the thing that changes, then name what must not. Skip the second half and you get a redesign; a redesign of a house you already live in is not a renovation plan.
“Remove the wall between the kitchen and the dining room” lands. “Open the place up” does not — there is no way to tell which wall you meant. If your plan has room names printed on it, use those exact words; that is what the drawing is read back against.
Add “and keep every other room, door, window and dimension where it is”. A dozen words, and they are the difference between a redraw and a new house.
Two changes in one sentence usually come back as one change and a guess. Each run is saved as its own version, so stack them instead: take the wall out, then add the furniture to that version.
“5 ft deeper along the top wall, so the kitchen, dining room and living room each gain 5 ft” beats “add 5 ft”. A figure on its own has a habit of changing the dimension line and leaving the wall where it was.
| Asked for | Came back |
|---|---|
| Remove the wall between the kitchen and the dining room | Done. The two rooms came back as one and the rest of the house held — except the door between the kitchen and the hall, which came back hinged on the other side. Pictured above. |
| Turn the garage into a bedroom with a closet and a window where the garage door is | Done, and it numbered the new room BEDROOM 3 on its own. Pictured above. |
| Furnish the plan, everything at the size it takes up on the floor | Done: beds, wardrobes, a sofa facing a TV, a six-seat table. Walls, labels and figures untouched. Pictured above. |
| Move the bathroom door a few feet along the same wall | Not done — twice, once with the door circled in red and once described in words. See the next section. |
| “I would like to add 5 ft. across the top of the floor plan and a 15 ft patio” (a subscriber's own words) | Half done: the figures changed, the walls did not. Written out in full it drew the patio, but the extra 5 ft still only reached the numbers. |
Five single runs on one plan, September 2026 — a record of what we got, not a benchmark. The two that failed tell you more about where to spend your evening than the three that worked.
No — and on the one change where we tried it, the mark is what went wrong. Red ink drawn on the image before you upload it is not an instruction to the model; it is more drawing. Sometimes it is read as the thing to act on, and sometimes as part of the house.
The same change with no circle, described in words, missed too: it put a door on a cupboard and left the bathroom alone. Nudging one opening a few feet along its own wall is the weak spot, whichever way you ask. Everything else on this page is something you can name — a wall, a room, a use — and naming is what works.
Marking inside the editor is a different thing and does help: there the mark is a selection the tool hands to the model along with your sentence, not pixels it has to interpret. If your plan has no room names to point at, describe the spot instead — “the wall between the two rooms at the top left” — and leave the drawing clean.
Marking, versions and what each kind of change costs: How to edit a plan you have already generated
“SURELY THERE MUST be an app where I can upload my floor-plan and arrange furniture over it? I've tried 5+ apps”
Yes, and it is the one change that never touches a wall. Name the rooms and the pieces — “a double bed and a wardrobe in each bedroom, a sofa facing a TV, a table for six” — and everything is drawn at the footprint it really takes up.
What it is not is a drag-and-drop furniture editor. You describe the arrangement you want and get a version of it; if it is wrong, the next version is another sentence rather than another hour of nudging icons. The rooms people fuss over most have pages of their own.
Room by room: Bedroom layouts
This page needs a drawing to change. Three ways to get one, in the order most people find them.
The builder's handover pack, the estate-agent listing from when you bought, the lease plan, or a copy held by your local authority's building control. Photograph or scan it and upload it as is — photocopies, faxes and old paper plans redraw fine.
Faint, creased or hand-drawn? Redraw it clean first
Pace or tape the rooms, write the figures straight onto a rough sketch, photograph that. Two things decide whether the plan comes back looking like your house: a size for each room, and which wall each window and door is on. People rarely write the second one down, and it is the one that shows.
A room-by-room way to do it: How to measure a room for a floor plan
The builder or developer, the managing agent, the previous owner's agent, or the council. Worth one email before you spend an afternoon with a tape measure.
Partly — and it is worth knowing which part. One subscriber typed this into the tool, word for word:
“I would like to add 5 ft. across the top of the floor plan and a 15 ft patio.”
So: something added alongside the house — a patio, a deck, a garage, a room off the back — comes back drawn. Pushing an exterior wall out by a few feet is the change most likely to come back as new numbers on the old walls. Look at the walls before you look at the figures.
A home addition plan and a second-storey plan are the same job as any other change here: name the wall the addition joins, say how deep and how wide, and say that the rest of the house stays. A second storey follows the outline of the floor below, so say that too.
In the UK, searches for extension plans land on practices selling council-ready packs — from around £795 plus VAT at the cheap end to roughly £1,700 for a fixed-price set. That is a different product, and this page is not a substitute for it. What you get here is a layout to think and talk with before you commission anything.
It works the same way on a builder's standard plan, changed before anyone signs: move the laundry to a wall that can take a dog door, make the pantry deeper, turn the study into a fourth bedroom. Same job, same sentence — the plan exists and you are changing one part of it.

What each plan includes: See pricing
Three different products get bought for this job, and they are not really competing. Worth knowing which one you need before you pay for the expensive one.
| Route | Typical price | What you get |
|---|---|---|
| Architect or designer for a remodel | Quotes people report run into the thousands | Judgement, structure, and drawings that can be built from. Homeowners posting about it describe “$5K+ quotes to redraw the entire house”, and one who paid for kitchen remodel plans wrote: “got a 10k bill and we don't even have construction drawings yet”. |
| A redraw service | About $20–$38 a floor, 24–48 hours | A person redraws the plan you send them, cleanly and to a house style. They redraw what you give them; deciding what the change should be is still your job. |
| This page | 3 credits a version at 2K, 6 at 4K | A version in a minute or two, as many versions as you want to try. Pro is $19 a month for 150 credits — about 50 versions; Studio is $39 for 400; a 100-credit pack is $29. The first version needs no account, and signing up adds 3 credits; those last 30 days. |
The first row quotes homeowners on Reddit, not a survey — it is there as the reason people end up on a page like this one, not as a price list.
