Living area under the WoFlV. Traceable to every part of a room.
One walk-through with a LiDAR iPhone or iPad. weScan delivers floor plans and a living-area calculation under the Wohnflächenverordnung (WoFlV), the German living-area ordinance: with clear heights, the weighting for each part of a room, the calculation path and a colour-coded area plan. For commercial space, rental area under gif MF-G; for design and construction, floor areas under DIN 277.

Which area applies to what.
Germany has no single floor area. For housing the WoFlV is the benchmark, for commercial space the gif guideline, for design and construction DIN 277. The report always names its basis.
Wohnflächenverordnung (WoFlV)
Floor area from the clear dimensions between building elements. Rooms with at least 2 m clear height count in full, from 1 m at half; balconies and terraces usually at one quarter, at most at half.
DIN 277:2021-08
Floor areas and volumes of buildings: gross floor area (BGF), net room area (NRF) and gross volume (BRI). Not a substitute for the Wohnfläche (living area), but often asked for in the same job.
Rental area under gif MF-G
The guideline of gif, the German Society for Property Research, for office, retail, hotel, logistics and mixed-use buildings, with a colour-coded rental area plan for each unit.
Usable floor area for the certificate
An Energieausweis (energy performance certificate) is required to sell or let; it states the building’s usable floor area (Gebäudenutzfläche) or net floor area. We give the issuer the areas and geometry from the scan.
Six rules that change the figure.
Counted in full
Rooms and parts of rooms with at least two metres of clear height count in full.
Counted at half
Between one and two metres the area counts at half; under one metre it does not count.
Usually one quarter
Balconies, loggias, roof gardens and terraces usually count at one quarter, at most at half.
Stairs stay out
Stairs with more than three risers, and their landings, are not part of the floor area.
From the face of the finish
Measured between building elements, from the front face of the plaster or cladding; walls do not count.
A defect in the rental
If the living area is more than 10 % below the figure in the lease, that is in principle a defect (Federal Court of Justice, BGH, VIII ZR 295/03, 2004).

The Building Modernisation Act takes effect
The Building Energy Act (GEG) is now the Gebäudemodernisierungsgesetz (GModG). The Energieausweis duties (§§ 79–88) stay: valid for ten years, shown at the viewing at the latest, required details in property ads. Changes from the EU buildings directive have been announced.
