The CityGate I – Marchandises development combines housing with multiple activities in modular spaces, offering flexible areas for commercial, office, and service purposes (workshop areas), along with a new private roadway along the railway track. It features community gardens and an interior green courtyard. Three architecture firms designed different sections of the development, unified by a common concrete brick grid. Each section has its own architectural identity, incorporating wood, plaster, or corrugated metal elements into the façades. The varied functions within the building foster an active communal environment, adding value to each space.
