The center is located on the border between the “Ensanche” and the “Gracia” neighborhood within an existing building that includes three different uses: 32 dwellings for elderly people, Primary Care Center and parking for 44 vehicles. The center occupies the first three floors of the building and the first basement. The distribution of surgery and waiting rooms is conditioned by the strict dimensional requirements of the center and the intention to take full advantage of the possibility of natural lighting and ventilation. To do so, the mezzanine floor is pulled apart from the façade, generating an elevated ramp that acts as a hallway, and works as an extension of the street as a space of relationship. In terms of energy efficiency, the building is one of the four High-Combi pilot projects of the VII European Union's Framework Program, for high-performance solar thermal buildings, and has achieved an Energy Certification A label.
