  • The project consists of 30 social housing units, 15 of those were rehabilitated from an old building, and the other 15 are new.
  • The rehabilitated units were insulated to improve the energy efficiency and lower the heating and cooling necessities.
  • The structure of the new building is made of wooden frame.
  • The project integrates rainwater collection for irrigation and solar panels for water heating.
  • The operational carbon of the new units is 49,3 kWh/m2/y and of the rehabilitated units is 67,4 kWh/m2/y.

Project description as provided by the Architects.

The first four-storey collective housing building made entirely of wood in the capital, “Head in the Clouds” escapes the many constraints imposed on it. The plot located in a fairly dense urban fabric was then closed by a building built on the street registered as a historical monument. Only accessible through a narrow porch, the rear housed masonry garages. Rehabilitating the building on the street, we chose to build the rear extension entirely in wooden frame. The speed and the cleanliness of the site are an obvious advantage of a project that can be implemented without heavy construction machinery, which can pass under the porch and work on a thin strip of the land, releasing a generous collective garden and allowing the implementation of boxes overhanging the facade, giving many additional rooms and terraces for each accommodation.
