The Cesson-Via Silva station on metro line B in Rennes (France) is the first station of the future ViaSilva eco-city, which is currently under development. Located in an urban square, it is raised nine metres above the ground by the viaduct over which the tracks and trains pass, and so it also serves as a viewpoint.
The ovoid-shaped station is constructed using a stainless-steel metal mesh that wraps around the viaduct without touching the infrastructure. This is made possible by the fact that it is supported by a system of beams, which also frees up the interior space of the station for platforms, ticket offices and transit areas. In the interior, to counterbalance the stainless steel and glass, oak wood ceilings have been installed, which not only provide warmth, but which also serve as acoustic insulation.
