The new École de commerce et culture générale is a college providing training in the fields of commerce, health, social and teaching. The design of the college offers a typology that meets the requirements and specificities of the level of education and training it houses. A ring of classrooms is served by a balcony passageway overlooking the large central space bathed in light. This central space, occupied by the play of flights of stairs, becomes the college's space of reference and identity. The classrooms arranged around the periphery of the central space enjoy a variety of orientations.
