Where to Draw a Floor Plan With AI for Free

The short version: you can draw a decent floor plan with AI for free using RoomSketcher, Floorplanner, Planner 5D, SmartDraw's free trial, or Canva's AI floor plan maker, but every one of them caps you at low resolution exports, one or two projects, or watermarks until you pay. If you want something you can print and hand to a builder or landlord, budget for one paid export rather than fighting the free tier for three hours.

What "free" means with these tools

Nearly every AI floor plan tool on the market runs a freemium model. The drawing part is free. The bit that costs money is almost always the export: a high-res PDF, a 3D render, or removing the watermark. I've tested enough SaaS free tiers in my work as an AI consultant to know this pattern by heart, and floor plan apps follow it exactly.

So when someone asks "where can I draw a floor plan with AI for free", the honest answer is: everywhere, right up until you want to use it for something real. Here's what you get without paying a penny on each of the main options.

RoomSketcher

RoomSketcher has an AI-assisted floor planner where you can sketch walls, drag in furniture, and generate a 2D plan in a browser, no download needed. The free account lets you create and save floor plans and view them in standard quality. Want a high-resolution 2D image, a 3D photo, or a Live 360 view? That's a paid "Visual" starting at a few pounds per plan, or a subscription if you're doing this regularly. For a one-off plan of a flat or small office, free is usable.

Floorplanner

Floorplanner is one of the oldest names in this space and now has AI-generated layout suggestions where you describe the space and it proposes a starting plan. The free plan gives you one project at a time and a basic 2D export. If you need multiple floors, a 3D walkthrough, or to keep more than one project live, you're into their paid tiers, which run roughly £5 to £30 a month depending on what you need. For drawing one room layout to send to an interior designer, free covers it.

Planner 5D

Planner 5D leans harder into AI than most, with an assistant that can generate a layout from a text description or a rough sketch and then let you refine it in 2D or 3D. The catch: a lot of the furniture catalogue and the premium render quality sit behind a subscription, and exporting a clean, large image often nudges you toward paying. Still, for sketching the bones of a floor plan, the free version is enough.

Canva's floor plan maker

Canva isn't a dedicated architecture tool, but its drag-and-drop floor plan templates plus Magic Design features let you throw together a clean, presentable 2D plan fast, and the free tier is more generous than most of the dedicated floor plan apps for basic exports. If you just need something that looks tidy for a planning application cover sheet or a simple house share listing, Canva is underrated for this.

SmartDraw

SmartDraw has floor plan templates with smart shapes that snap walls and doors into place, which speeds things up a lot compared to free-drawing. It offers a free trial rather than a permanent free tier, so treat it as a short, intense session: get everything drawn and exported before the trial window closes, because once it does you're paying.

A worked example: say you run a two-desk home office and want to replan it

Let's say you run a small consultancy from a converted spare bedroom, roughly 3.2 metres by 2.8 metres, and you're adding a second desk for a part-time assistant. Here's how that plays out in one of these tools.

• Step 1: measure the real room with a tape measure, not a guess. Write down wall lengths, window positions, and the door swing. This takes ten minutes and saves you redoing the whole plan later.
• Step 2: open RoomSketcher's free floor planner and set your wall dimensions to match exactly what you measured, 3.2m by 2.8m. Draw the door and windows where they really sit.
• Step 3: use the AI layout suggestion (or Planner 5D's text prompt if you're using that instead) and type something like "two desks facing opposite walls, filing cabinet by the door, bookshelf under the window". It'll propose a layout in seconds.
• Step 4: the AI suggestion will almost certainly get something wrong, usually the filing cabinet blocking the door swing or a desk too close to the radiator. Drag it to fix it. This is the part people skip, and it's why so many AI-generated plans look fine on screen and fail the moment you try to live in the room.
• Step 5: export in standard quality for free to check it against the real room one more time, then pay the one-off fee (typically £5 to £10) for a high-res export if you're sharing it with a builder, a landlord, or a flatmate who's splitting the desk cost with you.

Total cost for a usable, accurate floor plan: zero to about £10, and maybe forty-five minutes of your time once you factor in the manual measuring. That measuring step is the one the AI can't do for you, and it's also the step most "draw a floor plan in minutes" marketing conveniently skips over.

The uncomfortable bit nobody selling these tools wants to say

AI floor plan generators are good at making something look professional. They are not good at knowing your actual walls, your actual plug sockets, or whether your actual staircase has a weird turn in it. Every one of these tools works from either a template or from dimensions you type in yourself. If you type in the wrong number, or skip measuring the room because the AI felt like it was doing the work for you, you'll end up with a plan that's confidently wrong.

I see the same pattern in marketing AI tools: the output looks finished, which makes people trust it more than they should, and the actual thinking (measuring the room, checking the numbers, sense-checking the suggestion) still has to come from you. A free AI floor plan tool will happily generate a beautiful plan for a room that doesn't exist. Treat the AI as a fast drafting hand, not a surveyor.

If you're planning anything that needs to go to a council for planning permission or to a mortgage lender, none of these free consumer tools are a substitute for a real architect's drawing. They're brilliant for furniture layout, a house share listing, an Airbnb floor plan, or working out if a second desk fits. They are not building regulations documents.

When a quick AI plan is enough

Not every floor plan needs an architect. If you're doing any of the following, a free AI tool is the right level of effort:

• Working out furniture placement before you buy a new sofa or desk
• Creating a listing floor plan for a room-to-rent advert
• Planning a small home office or studio layout like the example above
• Sketching a holiday let or short-stay layout so guests know where things are, the same practical mindset I'd apply when planning a self-catering stay and wanting to know the space before you arrive
• Mocking up a kids' play corner or a home gym area where you want to check you've got room for the kit, the same way I'd think through space before suggesting home workouts that don't need equipment in the first place

For anything structural, load-bearing, or going in front of a planning officer, pay a real architect or structural engineer. That's not me being precious about it, it's just where the free tools stop being safe.

A quick word on offline access

Every tool above needs an internet connection to run, because the AI suggestion engine lives on their servers, not on your device. If you're drafting a plan somewhere without reliable wifi, like on a train or in a building with no signal, none of these will work, which is a different problem from the one solved by sites listing games that work with zero data for killing time offline. Download your measurements into a plain notes app first, then do the actual drawing once you're back online.

My honest shortlist

If you want one tool and no more browsing, start with RoomSketcher for a clean 2D plan with light AI help, or Canva if you just need something presentable fast and don't care about true-to-scale precision. Move to Planner 5D if you want to see the space in 3D before committing to furniture. Keep SmartDraw's trial for the day you need something finished in one sitting. And if the plan is for anything with legal or structural weight, that's the day you stop looking for free and call an architect.

Frequently asked questions

Can I draw a floor plan with AI completely free, with no catches?

Mostly yes for standard quality 2D plans in RoomSketcher, Floorplanner, Planner 5D, or Canva, but high-resolution exports, 3D renders, and removing watermarks usually sit behind a small one-off fee or a subscription.

Which free AI floor plan tool is most accurate?

Accuracy depends on the measurements you enter, not the AI. RoomSketcher and Floorplanner both let you input exact wall dimensions, so they're as accurate as your tape measure, which is the part people usually skip.

Is an AI-generated floor plan good enough for planning permission?

No. These consumer tools are built for furniture layout and listings, not building regulations or planning applications. For anything official, use a qualified architect or surveyor.

Do I need to pay to export a floor plan I can print?

Often, yes, for a sharp, print-quality file. Standard screen-quality exports are usually free, but if you want something crisp enough to hand to a builder or print at full size, expect a small fee of around £5 to £10 on most platforms.
