“La Estación” emerges as the result of continuous research on mobility and routes, a project developed by three offices that explores a construction system to cover large clearings without supports and accommodate various users for short periods of time. Inspired by the work of Pier Luigi Nervi, «La Estación» is a structure based on the Catalan vault to allow the free passage of the train while creating a public space for the enjoyment of users, as if it were a large loggia , this project unites the exterior and the interior to form a transitional space where the vegetation diffuses the limits.
