The study analyses real estate transformations which enabled a considerable growth of the population in Paris from 1999 to 2010. This was a consequence of building permits granted between 2006 and 2012 being exploited.
Paris recorded a constant rise in the surface area of available housing due firstly to new building which benefited largely from the contributions of development operations. The dynamics of the existing real estate played an even more important role in drawing new inhabitants with thousands of housing units being created due to the transformation of office and business premises, a sharp decline in the number of vacant housing units and a slight increase in the average size of households.
Contrasting with this, the surface area of offices remained stable or fell in most of the Parisian territory, the only significant increases being in the 13th, 15th, 17th and 19th districts where large public building operations were to be found.
