Defined term
Living area (Wohnfläche).
Wohnfläche / Nettofläche · Surface habitable · Superficie abitabile
Actual living area of an apartment in m², measured without balcony, cellar or attic.
The living area of a Swiss apartment is typically calculated per SIA standard 416 and includes all rooms inside the apartment: living room, bedrooms, kitchen, bathroom, hallway.
Not included: - Balcony, loggia, terrace (separately listed) - Cellar, attic - Common stairwells
Room counting: Switzerland counts all living rooms + kitchen as rooms when the kitchen is ≥ 10m². "3.5-room apartment" = 2 bedrooms + living room + 0.5 (separate kitchen or small office).
Rule of thumb m² per room: 25-30 m² per room is normal Swiss standard. A 3.5-room apartment is typically 80-100 m².
