Parisian designer Stéphane Malka Architecture has suggested creating affordable housing in the French capital by adding prefabricated elements on top of and between existing buildings.
The “3box” system does not require the purchase of sites. Instead, the right to build is obtained in exchange for renovating existing buildings.
According to Stéphane Malka, the housing would cost 40% less than the usual market price and could be built quickly and cheaply in workshops.
