Rehabilitation works have started on the Davout Félix Terrier building complex. Located in the 20th arrondissement of Paris, these HBM buildings dating from 1931 total 728 apartments served by 39 staircases. The project addresses the scale of the site, from the street to the heart of the block, as well as the scale of each of the buildings, from the common spaces to the housing units. The intervention, carried out on an occupied site for Paris Habitat, is being developed in association with Otéis, D&H Paysage and abc décibel.
