faced with the phenomenon of decohabitation, the need to construct new buildings

Building nearly 400,000 additional homes each year would provide dignified accommodation for all French people, according to a study. These new housing units would also be a solution to deal with the phenomenon of de-housing, also called “loosening”. “It’s the fact that we study longer and longer, and therefore that we need accommodation alone in our younger years more and more, that we age more and therefore that, here too, we stays longer in his accommodation And then, [il y a] the phenomena of blended families, of single-parent families, which means that, there too, where we needed only one accommodation, we need two today”explains Paul Meyer, general delegate of the National Union of Developers (Unam).

However, the population is decreasing, and many housing units are vacant. But this housing does not reduce demand, since they are not located on the outskirts of large cities or in employment areas. Housing needs are significant around large metropolises such as Lyon (Rhône), Bordeaux (Gironde), Toulouse (Haute-Garonne), Nantes (Loire-Atlantique) or Rennes (Ille-et-Vilaine).
