The building is located in an area that is developing quickly from a demographic point of view, in the 19th district of Paris, between l’Ourcq canal and the old railroad tracks of la petite ceinture. To address this changing context and favor urban fusion, the project proposes a program in seven floors that includes 98 housing units for students and thirty social dwellings, a shelter and three retail premises.

The commercial areas are on ground floor, facing the street, and so is the shelter, whose rooms and living areas face south and open up to a garden inside the city block. The rest of the building accommodates housing units, most of them open-ended, with bedrooms and bathrooms to the north and the living areas and kitchens to the south. While the southern facade has run-through balconies and living areas with curtain walls, on the opposite facade a series of greenhouses performing as winter gardens extend the interior space up to 2.1 meters deep. These act as multipurpose semi-exterior and private spaces, aside from permitting a better and more sustainable conditioning, because they function as adjustable climate control cushion.
