A lot with a very rugged topography, where the construction of the building is used to sew a dysfunctional urban area. A primary healthcare center with the challenge to define a facade for a new plaza located in the Montmelo town extension. Consisting of two very different volumes, it is a two-storey rectangular building intended for healthcare use, and that in turn will pick up three floors to the street below with a second access. Another building as a plinth, stands in front of the former. It is formed by three concrete walls with various lineups and it houses all the administrative area. The spaces between walls are sealed with concrete slats that act as brise-soleil and protect the activities of the place.
