PinPoint calculates the living area of a floor plan according to the national standard selected from the drop-down list when opening the Floorplan tool.
The available standards include Germany and 20 additional country-specific regulations (see the table below). While all standards are based on the respective published regulations, only the German standard has been fully validated against official reference calculations. The remaining standards are therefore considered experimental.
To support customisation and future enhancements, each country configuration is provided as a separate, editable file. This allows users to review and adjust calculation settings if the default rules do not fully meet their specific requirements.
Note: If a country configuration file is modified, it is strongly recommended to rename both the file and the corresponding ID defined within it. This ensures that custom configurations are not overwritten when updated default configurations are delivered in future releases.
The table below lists the implemented regulations and highlights any known limitations or important considerations for each configuration.

Country |
Metric (standard) |
Method |
Key caveat |
|---|---|---|---|
|
DE |
Wohnfläche (WoFlV 2004) |
Weighted 1.0 m→50%, 2.0 m→100% |
Validated reference; balcony 25%, half-rule + 0.13 m window-niche modelled. All others derive from this. |
|
AT |
Nutzfläche (MRG / ÖNORM B 1800) |
None (gross) |
No height reduction — confirmed by OGH case law (attic area below 1.5 m counts in full). Open balconies/terraces excluded per §17 MRG; loggias legally count but aren't auto-distinguished. No statutory min ceiling. |
|
BE |
Netto-vloeroppervlakte (Vlaanderen, Codex Wonen 2021) |
Room predicate (reaches 2.20 m, then area ≥ 1.80 m) |
Hard threshold, not graded: a room counts only if it reaches 2.20 m somewhere; under slopes area ≥ 1.80 m counts. The > 4 m² and 1/12 daylight rules are habitability warnings only. |
|
BE |
Surface habitable (Wallonie, AGW 2007) |
Weighted 1.0 m→50%, 1.8 m→75%, 2.0 m→100% |
Walloon graded coefficients — modelled exactly. Valid for Wallonia only. |
|
BE |
Surface habitable (Bruxelles, RRU Titre 2) |
Room predicate (reaches 2.20 m, then area ≥ 1.50 m) |
Rooms never reaching 2.20 m clear height are excluded; under slopes area ≥ 1.50 m counts. New-build habitable minimum 2.50 m drives the warning. |
|
CA |
RMS Area (RECA RMS) |
Room predicate (≥10% ≥2.13 m, then >1.52 m) |
RMS is defined to the exterior wall for detached houses → interior measurement reads smaller; below-grade area not auto-detected. |
|
CH |
Nettowohnfläche (SIA 416:2003) |
Cut at 1.5 m |
SIA 416 distinguishes NNF / NGF / construction area; a single net figure to interior faces is reported. |
|
DK |
Boligareal (BBR / BR18) |
Cut at 1.5 m |
Single height cut only; BBR shared-area / access-space rules not modelled. |
|
ES |
Superficie útil (RD 3148/1978) |
Cut at 1.5 m |
Single height cut; no separate common-area handling. |
|
FI |
Huoneistoala (SFS 5139) |
Cut at 1.6 m |
Single 1.6 m cut; no partition/shaft deductions. |
|
FR |
Surface privative (Loi Carrez 1996) |
Cut at 1.8 m |
Excludes lots < 8 m² and balconies/cellars/parking — not auto-excluded. 5% legal tolerance shown for information. |
|
FR |
Surface habitable (CCH R.156-1, Boutin) |
Cut at 1.8 m |
Excludes balconies/terraces/cellars/garages by law; relies on manual room tagging for those. |
|
IT |
Superficie calpestabile (DM 1975) |
Mean-height gate ≥ 2.7 m |
All-or-nothing gate: a room counts fully or not at all by its average height, so borderline attics flip in/out. |
|
MX |
Superficie útil (RCDF Art. 106) |
None (gross) |
No height reduction — confirmed (RCDF has no weighted-area method). 17.5% daylight window warning added (complementary rooms are 15%, modelled as one threshold). |
|
NL |
Gebruiksoppervlakte (NEN 2580) |
Cut at 1.5 m |
NEN 2580 deductions (shafts, stair openings, area under stairs) not automated. Reports Inhoud (volume). |
|
NO |
BRA-i (NS 3940:2023) |
Section + 0.6 m offset above 1.9 m |
The 0.6 m slope allowance is a geometric approximation, not yet validated against NS 3940 reference cases. Reports ALH. |
|
PL |
Powierzchnia użytkowa (PN-ISO 9836:1997) |
Weighted 1.4 m→50%, 2.2 m→100% |
DE-family two-band weighting; validated against the band table only, not reference dwellings. |
|
PT |
Área útil (RGEU) |
None (gross) |
No height reduction for área útil (RGEU Art. 79 uses habitability thresholds). Clear-height minimum corrected to 2.40 m (Art. 65; 2.70 m is floor-to-floor). |
|
SE |
Boarea (SS 21054) |
Section + 0.6 m offset above 1.9 m |
Same slope-allowance approximation as NO. |
|
UK |
Gross Internal Area (RICS / IPMS) |
Cut at 1.5 m |
Internal partition/column footprints are not included (area summed per room), so the figure is below true GIA. |
|
US |
Gross Living Area (ANSI Z765-2021) |
Room predicate (≥50% ≥2.13 m, then >1.52 m) |
ANSI measures to the exterior wall face → reported GLA is smaller; above/below-grade and finished/unfinished not distinguished. |
