The project is located in the future République district of the Ile de Nantes. It includes a mixed programme of housing and offices. The aim of the project is above all to be exemplary in environmental terms, and in particular to be a ‘low-carbon’ building complex. The proposal was therefore to build the entire super-structure in wood.
The plot is a quadrilateral formed by 4 wings around a central garden. The structure of the building is based on piles, with a lower floor supported by stringers. The upper floors of the ground and first floors are reinforced concrete. The upper floors, whether office or residential, are timber-framed, with the exception of the circulation cores. The timber structure comprises glulam posts and main beams, between which the floors are inserted. The walkways and balconies are supported by an external timber frame following a 3 m grid and leaning against the façade. The external joinery of the flats and offices on the upper floors is made of wood. The passageways consist of a steel trough floor working with a concrete slab and a wooden joist floor for the balconies. The external joinery in the shops and office lobbies is aluminium.
