The main façade alludes to the city’s shipbuilding tradition. The structure of the passenger building consists of a series of portal frames made of composite wood. The linear form of the building gives the station an imposing presence. The double skin made of fibre-reinforced concrete accommodates all the openings related to the various elements of the project and protects the façade from solar radiation. The north façade is mostly glazed and its openings allow views of the new TER platform. A footbridge allows access to the platforms and links Kerentrech district to the city centre.
