The B4 property complex includes 62 housing units and a student residence with 273 rooms located in two separate buildings. This arrangement, in addition to the autonomy which it provides for each entity, offers a more favorable east-west orientation for housing. Each building consists of a ground floor topped by nine levels.
The buildings maintain geometric and altimetric correspondences that connect them and the dialogue is reinforced by the use of similar materials. Each entity however expresses its functional specificity as closely as possible and develops its own identity.
The building with the 62 residences offers a horizontal stratification through the game of the balconies’ volumes. The other building is more monolithic and is made of a concrete frame which extends the building system on to the façade highlighting the different types of rooms.
