Rethinking workspaces in the heart of the city

Located on Place des Trois Fontanot in Nanterre (Hauts de Seine department), this former headquarter of The National Institute of Intellectual Property, vacant and obsolete since 2012, will be transformed into a new-generation office complex at the heart of the Peri-Defense business park.

Our architectural intention was inspired by the environment in which the project is located : although located in a dense urban environment, the BEL'AIR building is fortunate enough to benefit from facades visible from the public space and to open wide onto a square.
The existing volumes are uncluttered, and the choice of white to dress the body of the facade gives each floor its proper proportion. Sunbreakers, designed to reduce heat gain for the well-being of users, punctuate the façade. The recessed attic elegantly crowns the volume and has an accessible terrace.

The BEL'AIR building offers 5,400 sqm. of office and service space on 7 floors, including a cafeteria on the first floor, a collaborative space, a bicycle room, a roof terrace, and a 500 sqm. green terrace. The workspaces are modular, with various typologies and high clear ceiling heights. The use of radiant ceilings ensures the heating and ventilation of the office floors and promotes comfort.

On the environmental side, the BEL'AIR building is energy efficient and is aiming to obtain several certifications and labels: BBC Effinergie Renovation, HQE Excellent, BREEAM Very Good and WiredScore Gold level.
