Living area (Wohnfläche).
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: in German-speaking Switzerland the kitchen usually does not count as a room. A half room is often an eat-in kitchen with a dining area, a large hall or a small extra room, so a 3.5-room flat usually has a living room, two bedrooms and that half room. In Geneva the official statistics (OCSTAT) count the kitchen as a room, so a Geneva 4-pièces is roughly a 3.5-room flat elsewhere. Federal statistics (BFS) round half rooms down.
Comparing flats: compare the square metres in the listing, not only the number of rooms, because room sizes and the way rooms are counted differ.
