Size of the dwelling

The size of the dwelling is defined by the number of rooms or its surface area.

Number of rooms

At national level, more than half of the housing stock is comprised of dwellings with 3 to 4 rooms.

Floor space of dwellings

In 2020 the average floor space per dwelling was 99m2. The relative stability observed since 2000 (97m2) can be explained by the fact that dwellings built prior to 1981 (61% of the housing stock) have an average floor space of less than 100m2. The size of more recent dwellings, however, is larger, and dwellings built between 2001 and 2005 have an average floor space of 131m2.
