This particular 18th-century building, located in the heart of Paris, has had several owners and undergone many transformations. The new owner, a notary office, wanted to divide the large interior spaces to create more offices and meeting rooms in order to accommodate over 40 employees and host numerous clients.

The major focus was on the treatment of confidential spaces and their relationship with waiting or passage areas. The porosity of these boundaries was the solution that allowed for a clear reading of the existing architecture while bringing visual comfort and natural light to each space.

The partition walls of the meeting rooms on the ground floor are made of perforated chipboard laminated in oak, with a glass wall to control acoustic leakage. The perforation of the walls allowed natural light, coming directly from the skylight, to flow into each meeting room, while maintaining the necessary privacy for each space.
