The owners of this high-rise building wish to repurpose the ground floor as a public access area (training rooms). A cafeteria, located on the ground floor will function independently. It is designed to provide modular and multipurpose meeting areas, located at either end of the building.
A total surface area of approximately 43,000 sf / 4,000 m² will be added to the existing first five floors as well as to the first underground level.
The building’s extensions will be geometrically created by means of a broad curve on the lower floors, thereby creating a thicker building at its base than the existing one. The 5 levels of parking will be retained, providing 303 places. The building as a whole will be able to be divided into two distinct buildings with independent entrances opening onto two vast lobbies. Each floor can be divided into two units, making it possible to offer wide-ranging modularity in the layout of leased spaces.
To provide more natural light from above, the inter-company restaurant will be moved to the first underground level, thereby creating a large void visible from the street. This opening will be covered by a broad awning along the street, bordered by a façade, restoring the building to the urban scale.
Emphasis will be placed on the thermal and acoustic treatment of the façades, accessibility for persons of reduced mobility and the comfort of users.
