The project to build 8 housing units for the OPAC in the very heart of Paris involves a combination of quality objectives which blend architectural research with environmental exigencies.

The land on which the project is located is a very narrow north/south oriented plot. We therefore designed a dual faceted project with an urban facade to the north projecting a powerful image of compactness. The base is characterised by a light-coloured rendering which has been applied with hollow joints.
As for the cap of the building, it is a completely wooden structure, with a cabin set on the roof, harking back to the imaginary towns we all created in our childhood. A thick strip of plants reinforces this same spirit.

The entire roof has been treated like a solar power cell.

A very compact frontage on the North in order to limit the energetical losses and to inscribe the project into the urban continuity on street.

A very opened frontage on the South in heart of islet, in order to take advantage of the free sun bringings on the terraces and also on the roof thanks to photovoltaïc pannels.

The balconies are formed like wooden boxes that play the part of small greenhouses. They also cut the direct sunrays on the windows to avoid overheat in the summer.
