Drop in the aerial photo of your plot, then sketch the walls, the patio, the pool and the trees, all to scale. No architect needed: in one evening you'll have a clear floor plan to show your builder.
Made in Belgium, with the official aerial photos of Wallonia, Flanders and Brussels.
“Add a 6 × 4 m deck on the south side”
24 m² wooden deck added
How it works
If you can use an online map, you can use Architektor.
The aerial photo of your plot drops in at the right scale. No exact address? Import a plan or a PDF instead.
Type a wall length, “4.5m”, and snapping lines up the rest. Or just say it out loud.
Send a link they can open without an account, or a scaled PDF that's ready to print.
Levels
Like sheets of tracing paper stacked on top of each other, all to scale. Show one on its own, or keep the others see-through to check where the pipes run under the future patio.
As many floors as you need, each at its own height, linked by your stairs.
Walls with their real thickness, doors, windows, and the floor area of every room worked out for you.
Lawn, paths, patios, pool, trees, hedges and fences.
Water, sewer, rainwater, electricity, gas, fibre and drainage, with pipe size and depth. Rainwater tank, septic tank, inspection chambers.
Features
Your plot
Type your address and the aerial photo slides in under your plan, at real-world scale. You draw the house straight on top, without getting the tape measure out.
Sharing
Send a link and choose what it shows: the utilities for the plumber, the garden for the landscaper, the house for the builder. Everyone opens the plan in their browser and pins their notes right where they belong.
Materials
Your deck looks like a deck and your lawn looks like a lawn. One click and you're back to a clean “architect drawing” look, better for printing.
Wood
Pavers
Gravel
Travertine
Parquet
GrassDesign options
Every version is saved. Branch off a new option from any point in the history, change it as much as you like, then lay it over the other one to see what's different.
If you'd rather say it
An assistant (Claude, by Anthropic) edits the plan for you: “move the pool 2 m to the west”, “add a hedge along the fence”. It runs on your own Anthropic API key, billed by Anthropic based on usage. Everything else works without it.
An email, a password, and you're drawing.
What people use it for
Draw what's there in grey and the extension in red, then check the square metres before you meet the architect.
Place the pool and the deck to scale on the real photo of your garden, well clear of underground pipes.
Lawn, borders, vegetable patch, gravel paths, hedges, fences, and trees with the real spread of their canopy.
Record where the water, gas, electricity and sewer pipes run, and how deep, before anyone starts digging.
FAQ
Everything you need to know before drawing your first wall.
Yes. Drawing, levels, versions, aerial backgrounds, link sharing and PDF and PNG export are all free, with no subscription, no credit card and no ads. Only the AI assistant and the photo renders use your own API key (Anthropic for the assistant, Gemini for the renders), billed directly by those providers.
Yes, the assistant runs on your own Anthropic API key. Anthropic bills you directly, based on usage and at its published prices, and Architektor takes no cut. You can set a spending limit in your Anthropic console. Your key is encrypted with AES-256-GCM on our server and is never sent back to your browser. Without a key, everything else in the app works, and your browser's voice dictation is free.
Your plans are saved online in a Postgres database hosted by Neon, and the app runs on Vercel. Your plans stay yours: we don't sell anything, there are no ads and no tracking, just a session cookie. Nobody else can see a plan unless you create a share link, which you can switch off at any time. You can also delete your account and all its data.
Architektor is a sketching tool: it helps you think, measure and talk through your project, with the standard planning colours and scaled PDF exports. It doesn't replace an architect or a surveyor. Depending on your project and where you live, you may be required to use an architect, so bring them your plan and you'll both save time.
Yes. In Wallonia, the background uses the official SPW aerial photo. In Flanders and Brussels, the one from Digitaal Vlaanderen. Everywhere else, satellite imagery takes over. Drawing, dimensions and exports work anywhere, in metres.
Architektor runs in the browser, with nothing to install. For comfortable drawing, a computer with a mouse or trackpad is still best: the editor isn't optimised for touch on small screens yet.
Create a share link: they open the plan in their browser, without an account, and can zoom, measure and leave notes directly on the plan. You choose what they see: the whole plan, just the underground utilities, the garden or the house. You can also export a scaled A3 or A4 PDF (1:50, 1:100, 1:200…) with a title block, or a PNG image.
Yes. Import an image or a PDF (an architect's drawing, a land registry extract, a scan), then set the scale by clicking two points whose distance you know. You then draw on top of it.
Free, in your browser, nothing to install. And no architect needed.
