In Bordeaux, the Mokuzaï office building delivers 7.516 m² of office space in a mixed wood-concrete structure

Nexity and Cogedim have delivered the Mokuzaï building in the Belvédère district, within the Bordeaux Euratlantique development. Developed as a joint venture with equal shares, the building becomes the new departmental headquarters of the Gironde Agricultural Social Security Fund, which is the owner-occupier.

The Gironde branch of the Mutualité sociale agricole (MSA) is moving into the Mokuzaï office building, which will be delivered at the end of June 2026 in the heart of the Belvédère district in Bordeaux. Developed jointly by Nexity and Cogedim (50/50), the project comprises 7.516 m² of office space.

Offices spread over six floors

Designed by the architecture firm IT'S, Mokuzaï comprises a basement level, a ground floor, and six upper floors. Its layout combines a reception area, workspaces, meeting rooms, as well as technical facilities and bicycle storage.

The office floors have accessible terraces from the first to the sixth floor. The basement provides 40 parking spaces.

The program also includes 1.142 m² of green outdoor spaces, divided between roof terraces and a landscaped area for the employees of MSA Gironde.

A mixed structure combining wood and concrete

The building rests on a mixed wood-concrete frame. It is equipped with raised access floors and radiant ceilings designed to contribute to the thermal comfort of the workspaces.

Heating is provided by the district heating network. Photovoltaic panels are connected to a building management system (BMS), which is responsible for monitoring and controlling certain energy equipment.

Two targeted environmental recognitions

The developers indicate they are aiming for BREEAM International New Construction certification at the "Very Good" level as well as the experimental Positive Energy and Carbon Reduction (E+C-) label at the E2C1 level.

At the delivery stage, the published documents present these two levels as objectives. Therefore, they do not confirm that the final certification and label have already been awarded.

The new headquarters of the MSA Gironde

The MSA Gironde is taking possession of the entire property as owner-occupier. This new headquarters will allow it to consolidate its activities in modernized spaces adapted to its organization.

“This new headquarters in Bordeaux represents a major and structuring step for MSA Gironde. It allows us to sustainably adapt our organization to changes in our environment, while strengthening the quality of service provided to our members,” said Daniel Abaléa, director of MSA Gironde.

A building integrated into the Belvedere district

Mokuzaï is located in the Belvédère district, on the right bank of Bordeaux. This area belongs to the Garonne Eiffel coordinated development zone (ZAC), itself integrated into the Bordeaux Euratlantique national interest operation.

The district is developing a mixed-use program combining housing, offices, shops, services and amenities. According to Nexity's presentation, the entire Belvédère area represents approximately 146.000 m² on 9,3 hectares, including 50.000 m² of office space.
