175 dwellings & Urban Densification on 3 ha
A complete overhaul of the public spaces has been undertaken with a view to handing them over to the city of Rennes. At the same time, this reflection is making it possible to rethink how the residence fits into the neighbourhood, as part of the restructuring of rue Claude Bernard and, more broadly, the Courrouze ZAC project. Habitat and Environment certification is being sought for all the homes.

Initially, the request from the project owner concerned the subdivision of a small strip of land along a busy railway line, on the edge of a residential area. The diagnosis carried out by CoBe highlighted the lack of connections of this small hamlet to the rest of the city. The agency proposed, prior to any construction, the creation of a new road linking the district to two roads of municipal importance. The new street induced a new urban sequence articulating different buildings.
The volumetry follows the hierarchy of the road network: the six-storey buildings protect the district from the nuisance of traffic and give a built front to the main road. They also form the gateway to the housing estate. The railway line is bordered with two rows of houses in a strip, each with its own terrace. The realization of this small ensemble, densifying a sector of individual houses while giving it back its urbanity, benefited from the cultural project acquired by the city, which accepted the modification of the PLU to adapt it to the project, and the listening capacities of the project owner, who was able to revise its budget to follow the transition of the order from 20 to 69 housing units. For CoBe, this project strategy is representative of an overall design method that could be applied in similar contexts.
