Built in the 70s, the Quartier du Pont de Sèvres is a city on slabs emblematic of the end of the Glorious Thirties, which is characterized by its density. Classified as a ZUS (Sensitive Urban Zone) in 1996, the development project for the district began in 2008. The priority is in particular placed on the renovation of public spaces, and particularly the passages of the Old Bridge in Sèvres and Aquitaine.

Formerly at the back of the city on the edge of the old Renault factories, the new public passages of the Vieux Pont de Sèvres are today a new entrance to the Trapèze district.

These covered passages are the most direct way to connect the Pont de Sèvres metro station, and the much more recent Trapèze metro station built on the site of the former Renault factories. Bringing together these two parts of the city was then essential to open up the neighborhood on slabs, breaking with the surrounding fabric.

The restructuring of the public passages of the Vieux Pont de Sèvres et Aquitaine is a continuation of the Forum space, an operation to redevelop car parks in the superstructure with sports equipment, delivered by Atelier du Pont in 2013.

Digging through a former aerial car park, cutting the concrete, finding natural light: the prerequisites for creating a new public space that meets the challenges of the district.

The old passage of the Vieux Pont de Sèvres - overlooking the eponymous street and located under two bars of 798 housing units built in 1976 by Daniel Badani and Pierre Roux-Dorlut - was only a connecting tunnel and an access road for firefighters, anything but a pleasant and safe pedestrian crossing. It was first necessary to bring this passage to the standards for all. An elevator and stairs, wider and more airy, have been created. By digging into the concrete, natural light and views were uncovered. Two stepped gardens are now side by side on one side of the passage. Dressed in terrazzo and polished concrete, the cleared passage offers passers-by a fluid, pleasant and secure crossing, with real spaces for breaks and contemplation.

One of the major difficulties of the site was to keep the life of the neighborhood running throughout the operation. The inhabitants of the two housing blocks continued to live on the spot, the existing businesses remained in activity.

Beyond a complex work on the public passages, the strong will of the City of Boulogne-Billancourt was to integrate sports and commercial activities in the shells located on either side of the Passage du Vieux Pont de Sèvres. Initially 3 parking levels, the spaces, once completely open, offer titanic heights. Very early on, the possibility of a climbing room was mentioned to exploit all the capacities of this place. 

A major challenge remained: to bring together the two shells located on either side of the passage to create a single space. Between flexibility, audacity and technicality, a tunnel is created to connect the two shells and offer, for the Arkose group, a truly urban and atypical place. Arkose has been developing city climbing complexes for several years. More than simple climbing spaces, they are real urban living spaces that promote meetings and exchanges with restaurants, bars, shops, fitness, yoga...

Atelier du Pont carried out all of the interior fittings for this new Arkose complex, which is inspired by the bivouac. The atmosphere is warm, through the integration of reused or second-hand furniture and natural materials, in a very urban interior, left raw with exposed networks and concrete walls on which elements are hung, suspended or suspended. grab. The atypical and labyrinthine configuration of the space made it possible to imagine a place to be explored, punctuated with evocations of nature.
