In 2021, Atelier du Pont (Anne-Cécile Comar & Philippe Croisier) delivered Bienvenüe, the head office in Paris (20th century) of RATP Habitat, the contracting authority. With 907 m² of terraces for 2,872 m² (SDP) – cost of works and interior fittings, furniture and signage: € 9.3 million excluding tax – a planted promenade invisible from the street but a surprising landscape for residents and users. Communicated.
Gain space where there is none
It is by passing under the porch of a housing building that one reaches Bienvenüe, the new headquarters of RATP Habitat. The building occupies the whole of the plot, the space consumed on the ground is thus compensated by a succession of gardens on the roofs.
Its post-beam frame is in glued laminated timber. It is woven into that of the existing car park to limit structural changes in the basement. The use of wood also makes it possible to reduce site nuisances for the neighborhood.
Two patios and an atrium structure the space, provide light evenly throughout the depth of the building as well as effective natural ventilation.
A core of services (sanitary, reprography, storage, etc.) takes place along the north of the building in order to free up the large workspaces which can be reconfigured as desired.
The interior stairs are made of load-bearing stringer wood and not enclosed to let in natural light. They encourage employees to favor the increase and to increase meetings.
Roofs planted and inhabited to work and relax
At Bienvenüe, RATP Habitat employees benefit from the landscaped and planted roofs. Very sunny, they allow you to work and relax in the heart of Paris. Areas of open ground and planted pots delimit the various spaces of these terraces where you can also have lunch, take a break, share a moment of conviviality or indulge in gentle sports (yoga, ping-pong …). The garden on the last level is dedicated to vegetable growing.
The three levels of these terraces are connected to each other by large staircases which manage to circulate from another building without going through the interior.
Arranged on the R + 1 and R + 2 terraces, small greenhouses allow you to hold meetings, organize brainstorming sessions or isolate yourself to work in the shelter.
Flexibility and user-friendliness of workspaces
Bienvenüe’s interior design breaks radically with the classic office model and responds to the contemporary challenges of workspaces: flexibility, scalability, multifunction and creativity. A good balance between the collective and the individual. The spaces are designed to be invested in different ways throughout the day (work, coffee, relaxation, meeting, video, etc.).
The two office levels are designed according to a free plan principle, reconfigurable thanks to the mobile partitioning and allowing the space to be adapted to various practices (shared offices, closed offices, landscape offices, nomadic offices, work and meeting spaces informal, collaborative spaces, creativity room, etc.) and their development.
The colors are soft and warm, the wood left visible, the fabrics comfortable, a subtle play in the selection of furniture creates a domestic atmosphere for more pleasant offices and collaborative spaces.
Bienvenüe’s ground floor is dedicated to welcoming the public and to the relaxation area (café, cafeteria, kitchen) where you can also hold informal meetings or ‘debriefs’ with your teams.
Evoking the plant with a graphic writing, the sculpture ” Standing Wood »Produced by Atelier YokYok occupies the atrium and covers it over its entire height (13 m high). Thanks to the seats at its base, the atrium becomes an agora where we meet to discuss, exchange, gather, take a break.
Atelier du Pont carried out a directional signage mission and created the window sticker for certain glass partitions which represent the fabric of the RATP network.
