ZAC Baud Chardonnet - L'Oasis
Coordinating Urban Architects for the ZAC Baud-Chardonnet
Architectural design and compliance mission, Oasis building
Project completed, 2021–2025
INNOVATIONS
The project makes full use of the plot through a controlled vertical stacking of the different programmes. The car park is designed to be reversible, anticipating a potential change in use over time.
The concrete structure, sized to accommodate the large spans required for retail spaces and parking, also serves as the organising grid for the upper floors.
The terraced houses complement this structure with timber framing.
At the heart of the scheme, the gardens—referred to as the OASIS—benefit from a substantial soil depth, allowing the planting of mature, large-canopy trees. Rainwater is collected and reused for their maintenance.
All programmes are connected to the district heating network. An internal energy loop is also implemented within the project, enabling the recovery of heat generated by the retail spaces and its redistribution to the housing, thereby covering part of the heating and domestic hot water demand.

A mixed-use development, embedded in the urban dynamic of the ZAC Baud-Chardonnet, combining retail spaces, housing, a senior living residence promoting intergenerational mix, and a car park.
The building is set out in alignment with the surrounding streets, the public square, and the pedestrian lane, integrating the plot into a clearly structured urban framework. Balcony overhangs of 80 cm, as permitted by the road regulations, project above the public realm from level R+2 (approximately 8.50 m), animating the otherwise smooth façades along the plot boundaries.
The volumetric treatment of this “perimeter block building” also follows a principle of vertical, stratified composition.
A continuous podium rising to R+2 occupies the entire site. This podium forms the lower stratum of the project, corresponding to “the city of pedestrians, social interaction, and parking.” It accommodates retail units, entrance lobbies, car parks, and technical rooms.
Above this podium, from R+1 to R+2, the residential volumes are developed. Three permeable openings, ranging from 5 m to 12 m in width, on the north, west, and south façades, create breaks in the built mass, clearly distinguishing between the different programme typologies and the varying building heights according to their locations (R+2, R+6, and R+8).
