Free floor plan maker · online · no sign-up
Draw the house, the plot and the networks: a dimensioned floor plan, a site plan on a map, electrics and water, PDF export at scale. On a phone as on a computer.
Tap a layer to show or hide it, as in the editor.
Everything you need to draw, check and print your project, with nothing to install.
KeyPlan²
Plan² draws a location plan and a block plan (site plan) to scale, with scale bar, north point, key and distances to the boundaries. In the UK, these are the plans a planning application asks for, and many councils want an Ordnance Survey based location plan. Elsewhere, check with your local authority which plans it asks for. Have them checked or signed by your architect or surveyor where required.
The IGN map and the cadastral parcel import are for France only for now. Elsewhere the map is OpenStreetMap, and you draw the plot yourself.
Location plan
Your site marked on a map, so the authority can find it. In the UK, usual scales are 1:1250 or 1:2500.
Block plan
The house on its plot, dimensioned to the boundaries. In the UK, usual scales are 1:200 or 1:500.
Floor plan
The plan of the house in black and white, ready to print at an exact scale.
Every tool has its strengths. Plan² makes an accurate 2D plan, from the plot to the networks, with no account and no subscription; its 3D view is planned, not available yet.

Plan² has no accounts and no plan server. Everything you draw lives in your browser tab, and nowhere else.
The one optional exception: the Site mode map contacts IGN or OpenStreetMap to show its images, never without your consent, and without sending your plan.
To keep a plan, export it as a file: open it again whenever you like, on any device. Closing the tab without exporting erases the plan, and the editor warns you first.
A 3D view generated from your plan, with a walk-through at eye level, is in the works. It does not exist yet and no date is announced.
Open the editor: a sample plan is waiting, with nothing to install.

No. Open the editor and start drawing.
In your browser, for the session. Export them as JSON to keep them and open them again later, as a PNG image or a PDF (A4 to A0, at scale) to show or print them, or share them as a link: the whole plan fits in the link, and is stored on no server.
Plan² draws the location plan and the block plan (site plan) to scale, with north point, key and distances to the boundaries, and the dimensioned floor plan. Heights, sections and elevations are coming soon. In the UK, your council may ask for an Ordnance Survey based location plan; elsewhere, check what your local authority asks for. It does not replace an architect or surveyor where one is required.
In Site mode you can open a map under the plan, only if you agree to it: IGN aerial photo and cadastre in France, OpenStreetMap elsewhere. In France, tap your parcel to import its boundary and area. Parcel import is France only for now.
Yes. You cut the plot with lines: each lot has a name, an area, a colour and its distances to the house, and a site plan can be exported for each lot.
Yes, in the Electrical and Water modes: circuits, ratings and cable sections, cold, hot and drain pipes. The NF C 15-100 checks are indicative; they do not replace an electrician or a plumber.
Yes. The editor adapts to small screens: placing with a viewfinder, long press, pinch to zoom, a strip of recent tools and a quick toolbox. It can also be installed as an app from the browser.
Yes, it is planned: a 3D view generated from your plan, with a walk-through at eye level. It is not available today and no date is announced. Meanwhile the 2D plan is complete and accurate.
Kozikaza closed in April 2025, and its plans were moved to Kazaplan, run by Leroy Merlin. Plan² cannot read those files, but redrawing a house usually takes a few minutes.
