80 Years of History

Built in 1927 by the architect landmark of the golden age of industry, had long been used to adolphe Bocage, this building, a produce telephone control units. located on the banks of the seine, the site, with nearly 7 acres and a 6-storey building, used to hold the lMT society (le Matériel Téléphonique). The building soon became a symbol of industrial innovation. The site had been designed in keeping with the great principles of the Modern Movement in architectureusing simple geometrical shapes, and reinforced concrete. In 1976, Thomson-CsF took control over lMT, who, at the time, employed 10 000 people. In 1988, seventy years after its construction, Thomson Multimedia transformed the factory into offices and set up its head quarters in the building, until 2009. 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. It is this ambitious decision that gave birth to the major IN/OUT project.

After our first commission to design a series of spaces for the Mandarin Oriental hotel in Paris, société Foncière lyonnaise (sFl), has asked us once again to embark on another adventure. This time, they have commissioned us to design a new amenities wing of their ambitious In/Out office campus, a landmark office project that is re-defining work spaces in France which houses a cafe, restaurant, board rooms, an auditorium as well as various technical spaces and the lobby, with his pavilion, of the historical building.

THE SITE'S NEW ORGANIZATION

The IN/OUT project involves an office « campus », of more than 387 500 square feet. It is located on a former industrial site in Boulogne, at the West of Paris, on the right bank of the seine river. This factory, which used to manufacture telephone tools in the 1930s, underwent a complete rehabilitation done by DTaCC architecture , such as many industrial sites in Boulogne. Visitors enter the historical building and are welcomed into a large vast space similar to a hotel lobby.at the entrance lies a large oval desk the 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 new amenities wing is nearly 40 000 sq ft.including the interiors. 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

THE AMENITIES WING

Agence Jouin Manku has conceived the new amenities wing (nearly 40 000 sq ft.), as well as the interior design of the wing. The building has been further developed in collaboration with the engineering office TESS and DTACC. The new wing also holds a series of services and amenities, alongside the workspaces within the ‘Bocage’ building (thus completing the IN/OUT campus). The wing holds: a 103 seats cafe, a 462 seats restaurant, a 200 seats auditorium, as well as corporate board rooms, lounges, 2 large terraces and a fitness center

× A dynamic shape, symbol of an avant-garde building

How can workspaces in big companies be improved? What is missing? This interrogation has guided the design of the amenities wing. agence Jouin Manku decided to create a very different atmosphere to complement the ‘Bocage’ building. This gives employees a healthy balance between formal and informal, as well as between work and play, an idea at the heart of the In/Out Campus. 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 concrete heart: the center of the building

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. On the outside, the density of the vertical wood cladding increases and decreases, depending on its position, and which indoor space it corresponds to. The pattern starts out smoothly, then its texture, created by adding chamfers, changes. These edges catch light differently and create a sense of depth on the façade. Inside, the main materials are wood, bush hammered concrete, plaster and curved glass. The curved wood that wraps a large part of the interior adds to the sense of warmth, while the simple use of glass and concrete add a crisp modernity to the project.

A footbridge connects the two buildings. This bridge, made of white painted steel and wood, makes access easy between the two buildings, and acts as a symbolic link between the two architectural signatures, and the birth of a common project.

× An architecture inspired by nature: an inside out and outside in design

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, created as an extension of the building. The flowing shapes of the project recall the movements of nature. To underline this idea, 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.

× The insides

The interior design and furniture have been thought out as a continuation of the outside lines of the building. While the central concrete core holds the curved staircase that links the various levels of the building, each level opens out on spaces filled with light: simple yet warm spaces, spaces that open out on terraces and gardens, as well as spaces that invite one to discover the next room. The circulation is therefore fluid, and the connection between each space is harmonious. employees can thus enjoy each space, and will always be invited to discover the next one.

The transformation of the lobby: a micro -architecture at the heart of the "Bocage"building

On the outside, the ‘Bocage’ building still looks like an industrial fortress from the 1930s. Yet inside, gently perched in the space of the old atrium, agence Jouin Manku has designed a “soft” space, filled with light, which is one of their trademarks. Visitors enter the building and are welcomed into a vast space, similar to a hotel lobby. at the entrance lies a large oval desk, which leads visitors to what used to be an indoor atrium. In the newly created courtyard, one discovers a surprising micro-architecture: a glass canopy, held up by a series of intertwined wood beams, an ethereal floating lattice, which at one point swoops down and gently balances above the floor.

This structural frame was a complex element that required the expertise of TESS, an engineering firm with whom Agence Jouin Manku regularly works.

This lobby is the new heart of the ‘Bocage’ building. It is a central meeting point between different spaces. It also invites visitors or employees to have a break. Both simple in its design and complex in its realization, the glass pavilion foretells the bold amenities wing designed by the agence Jouin Manku.

AN ENVIRONMENTALLY AWARE PROJECT

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 Ré- novation (the equivalent of BBC for renovated buildings), BreeaM Very Good and LEED GOLD.

AN ATTRACTIVE LOCATION

Ideally located on the right bank of the heart of the West of Paris. It is easy to reach, thanks to the metro seine, IN/OUT is at the stops (on lines 9 or 10) which are just a short walk away, the streetcar going from Porte de Versailles to la Défense, buses, embankment roads, beltway and underground parking

× The verticaL circuLation spaces

The other major architectural work is the transformation of the office spaces, especially through the vertical circulation spaces and service points, which now stand on the inside corners of the courtyard. This has created new circulation spaces around the lobby. In the upper floors, natural light now floods largely into the workspaces. Corridors and stairs are highlighted by a strong yellow color. This creates a contrast with the rest of the building and encourages one to use the stairs as well as the elevators

Conclusion

IN/OUT is an ambitious architectural project by DT tecture and agence Jouin Manku; together, they created two aCC archiunique buildings for SFL.

The campus offers a new approach to workspace based on the ideas of sharing, well being and collective activities. The renovation and construction have greatly improved the campus’ amenities, for the benefit of the future users .

This project also transforms a typical scenery of the seine river.
