Almost half of the building stock was built prior to the 1970s, while 17.8 % was built after the
2000s. There are significant differences between building types. 72.3 % of semi-residential
buildings were built before 1971 and the majority of those (52.3 %) were built even before
1945, whereas this is only the case for 48.1 % of apartment blocks. For single-family houses,
50.5 % were built before 1970 and 12.9 % over the last 15 years. Apartment blocks are gaining
in importance, so in terms of residential buildings built after 1995, the proportion of apartment
blocks is greater than that of the single-family houses. 103
Restoration or renovation of old buildings is more costly than demolition. Some 200
demolitions of residential and semi-residential buildings have been registered between 2011
and 2013 the majority of which concerned single-family houses. Buildings built before 1945 are
the most commonly demolished (69.1 %) and buildings built after 1981 only represent 2.2 % of
demolitions. 104

The statistical basis for non-residential buildings is less complete than that which exists for
residential buildings. In particular, there is an absence of statistical data for the period before
1970.
The table below gives an overview of the total number of buildings completed between 1970
and 2011, broken down by type of building.
