How can we densely rebuild an islet in the middle of an already highly constituted urban fabric steeped in history? What architecture should be designed for three new buildings in this context?

LNCSA Head Office

Boulogne-Billancourt (92)

Restructuring an urban parcel, drawing on the qualities of those that the city of Boulogne already has within its urban fabric, both dense, open and vegetated. To give back spatial coherence to a place where a private mansion and a few faubourgian buildings already cohabit without any apparent rule. To succeed in giving the desire to live as well as the desire to work around quality exterior arrangements. These are the issues that governed the design of this project.
Installed along the land boundary with the public roads and unified by constructions governed by a single grid, declined for tertiary occupation on one side, housing on the other, the 3 buildings-two tertiary and one residential-ensure a new coherent density to the block.
Thus sculpted by the land constraints, the architecture creates a small central park, sometimes visible from the street through the openings created by the interiors, sometimes hidden to preserve the privacy of the occupants.
Terraces and balconies oriented on the interior of the plot, assuming their co-visibility, offer places of urbanity and relaxation to users.
