Exceptional workspaces

The office floors have also taken on a new look: 2,700 m² now flooded with natural light, with direct views of the Opéra Garnier. A project in which the architectural gesture gives the building back its horizon. A complex worksite in an occupied building, but certainly one of the finest challenges the practice has taken on.
