Relax At Work: Office Building IN/OUT near Paris
Desinger: Agence Jouin Manku
Location: 46 quai Alphonse Le Gallo, 92 Boulogne Billancourt, Paris, France
SFL then decided to restructure the building, aiming for it to become a benchmark in the tertiary sector, focusing on innovation as well as on wellbeing at work. This ambitious decision gave birth to the major IN/OUT project.
SLF commissioned Jouin Manku to design a new amenities wing of their ambitious IN/OUT office campus. How can workspaces in big companies be improved? What is missing? This interrogation has guided the design. Agence Jouin Manku decided to create a very different atmosphere to complement the historic ‘Bocage’ building. The aim was to give employees a healthy balance between formal and informal, work and play.
Jouin Manku were inspired by the Saint-Cloud park, the Seine river and the lush nature just close to the site. The amenities pavilion has been designed to allow these elements to penetrate the building, as well as to create spaces that would allow one to enjoy the gardens and terraces.
The building is organized around a central tower made of bush hammered concrete, which holds all vertical circulation. The choice to use concrete for the center of the building was to create a coherence and dialogue with the neighboring ‘Bocage’ building, which is made of the same material and clearly shows its original industrial character.
Two wings revolve and wrap around the central tower, but they never meet. Their architectural lines are softer and each wing is a curved form, made of curved glass and vertical wood cladding. The spaces between the concrete center and the wood wings are filled with glass, which allows light to penetrate almost everywhere in the building, vertically or horizontally.
The structure of the ‘Bocage’ building evokes nostalgia, professionalism and rigor. In contrast, the new wing has been conceived as a building of contemporary architecture, designed around the idea of movement and flow. Its shape has been made to create a series of intertwined spaces. The building is organized around the idea of passage: passing of people, light and air. It is also a place which evokes movement, production, action and dynamism.
The roof of the wing has been designed as a colored envelope wrapping the building. The colored stainless steel tiles were chosen for their particular iridescent character. In front view, the tiles are green, but their color changes as the angle and light move. This gives the building a dynamic and always changing character, echoing the variations in the sky and sunlight.
Visitors enter the historical building and are welcomed into a vast space similar to a hotel lobby. At the entrance a large oval desk leads visitors to what used to be an exterior courtyard. In the courtyard one discovers a surprising micro-architecture: A glass pavilion that is held up by a series of intertwined and woven wood beams. An ethereal floating lattice which at one point swoops down and gently balances on the floor below on just one point. This new glass canopy in the central courtyard creates a natural transition between the lobby of the historical building and the amenities wing.
This building was further developed in collaboration with the engineering office TESS for the structural elements and the skin of the building and with architectural agency DTACC for the technical development and architectural execution.
IN/OUT is a benchmark in terms of environment: It is in keeping with the RT 2012 norms for new buildings. The campus has received French and international certifications: HQE, Effinergie Rénovation (the equivalent of BBC for renovated buildings), BREAM Very Good and LED GOLD.
