80 YEARS OF HISTORY

Built in 1927 by the architect Adolphe Bocage, this building, a landmark of the golden age of industry, had long been used to 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.

THE SITE’S NEW ORGANIZATION

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 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.

The « Bocage » historical building: a landmark of industry, between restructuring and construction.

DTACC architecture has chosen to focus on the historical building « BOCAGE » by designing a landscape and garden, in collaboration with landscape designer Pascal GASQUET.
A gentle slope now replaces the former parking access ramp.
The access and entrance to the building are then in harmony with the whole site, and ensure accessibility to people with disabilities.
The new amenities wing, designed by Agence Jouin Manku, has replaced the parking and now stands at the heart of the landscaped garden.

DTACC has chosen to remove the original partial glass roof that once fully enclosed the central courtyard of the historical building, to create an open air garden. The new Glass canopy in the central courtyard, designed by Jouin Manku, creates a natural transition between the lobby of the historical building and the amenities wing.
The organization and structure of the various spaces, the choice of the different scales, as well as the harmony between mineral and natural elements, give the place its « campus » touch, sought by SFL.

Restructuring the « Bocage » building
DTACC architecture
How can a landmark of the industrial landscape of the 1930s, with its historical and architectural identity, be in keeping with the 21st century?
How to create a special work environment, which will have more to offer than any other office building?
DTACC provided original answers to these major interrogations.
From the first sketches, DTACC identified the unique possibilities of this historical site. The agency succeeded in transforming the site, while both respecting its original architectural identity and introducing contemporary elements. The DTACC project reflects all the major stakes of the contemporary use of such a building.
