Stéphane Malka Architecture has been commissioned by the 16th Arrondissement of Paris to "plug-in" extensions into a 1970s residential block.
The extensions will be a mixture of bow-windows, loggias, galleries or rooms.
The boxes will be made from wood particles, which allows them a "lightness and a great flexibility of implementation on site".
Each cube will factory-made to be directly inserted into the building.They have been made possible by the 2014 Access to Housing and Urban Renovation Act, which relaxed planning restrictions.
Stéphane Malka Architecture noted that most buildings of this period had poor energy performance owing to the presence of thermal bridges, bad insulation and the old standard of windows.
The architect has calculated that as well as increasing living room, the extensions will reduce energy use from 190 to 45KWh/m2/year.
