Urban transition and new orientations. Carmelites Extension adds two floors on an existing volume and reorganize entirely the plan with a creation of a patio, transforming an urban house into a two apartment construction, a duplex on the two first floors and a triplex above it.
Situated between a high and a low building, the project become an opportunity to link the two different scales of the street. The roof extension becomes a way to finish the street with creations of terraces and new orientations instead of a blind wall.
The transition between the different heights of the neighboring constructions is progressive.
