Carrez area checked on the plan
Drop in the plan of a unit: every room is measured in real m², the habitable total is shown, and rooms under the 9 m² threshold or under the required height are flagged before you sign anything.

An area error is paid for in a price reduction
When selling a unit in a co-owned building the stated private area binds the seller. A gap beyond the tolerance opens the door to a price reduction claim, proportional to the shortfall. Yet this figure is routinely copied from an old deed, a listing or an archive plan without ever being cross-checked.
FloorScan measures the plan for you: every room in real m², the total, and warnings on rooms that are too small or too low for the height you enter. It is not a certified measurement, it is the sanity check missing before you send a surveyor or publish a listing.
What you get from the plan
Area schedule
Every room named, its area in real m², its perimeter, and the habitable total for the unit.
Under 9 m² warning
Habitable rooms below the threshold are listed by name with their measured area.
Ceiling height
You enter the unit's height and the compliance check uses it for its verifications.
Old plans and scans
Detection works on the image: a scanned print or a photo of a plan is enough, no CAD file needed.
One-click correction
A badly closed room outline is fixed with the mouse and the area recomputes at once.
Report to attach
The schedule exports to PDF and Excel with the annotated plan, for the sale file or the mandate.
Area calculation questions
Does the result count as a measurement certificate?
No. A binding measurement is done on site by a professional who takes on liability and records the actual state of the unit. FloorScan measures a plan, not a home: it is a preparation and cross-checking tool, not a certificate.
Are balconies and cellars counted?
Every detected room carries its name and area, and you decide what goes into the total: spaces outside the private area are deselected before export. Nothing is aggregated behind your back.
How accurate is a plan-based result?
It depends first on the scale: one legible, exact dimension gives areas reliable to the hundredth on a vector plan, a little less on a noisy scan. The delta that matters is never in the third decimal, it is in the room nobody had counted.

I already have an accountRoom-by-room areas come from our floor plan area calculator. If the space is poorly split, our page to optimize an apartment layout tests other arrangements. To keep the load-bearing walls and change the rest, our AI floor plan layout tool suggests new arrangements. Quantities then come from our AI takeoff software, which counts walls, openings and areas.
