The bike station is a simple geometry. Wooden beams on a galvanised steel crinoline. They cross each other in an alternating butterfly pattern, to receive rooflights at the ridge. The roof, which provides protection from the elements, is made of photovoltaic glazing. In this way, the shed produces electrons that contribute to the renewal of the railway world and low carbon mobilities. The volume is naturally ventilated; the space is illuminated by the moucharaby of the solar cells and by the skylights, composed of some forty re-used glazing from the Centre Pompidou.
