The site is located in the east corner of the park "La Clota" on the northern edge of the city of Barcelona. It is a transition zone with a considerable slope of the consolidated fabric of the city and Mount Tibidabo, originally occupied by a few blocks of houses built during the migratory movements of the 50s and consolidated as area of ​​equipment during the early 90 on the occasion of the Olympic Games. The plot is a trapezoidal piece of about 3,500 m 2 with a drop in the short direction of 3.5 meters and substantially horizontal in the long direction. It has a good south-east and has magnificent views over Barcelona Park "The Clota" first. The project was to solve a program about 6,600 m 2 of social housing with 81 serviced apartments for seniors, 4 homes with support services (with separate access) and parking for 28 cars. In addition, there were a total of 1,500 m 2 of neighborhood facilities. All these uses must be compatible with the activities of the police station adjacent to the solar police. The building looks naturally inserted in place. Find yourselves seek and composition patterns and management in the immediate environment. The housing program was organized in two separate bars forming a united L downstairs. The building height PB gets +3 to your profile is the lowest possible. The best orientation for the houses were searched. Over 90% of the units have southeast orientation. This is a high comfort of habitability and a high savings in lighting and air conditioning of the apartments. The mass of the building is concentrated in the northern perimeter of the site, so that most of the surface was available for the volume of equipment while maintaining the highest standards of guidance and views. The strategic position of housing with support services and independent access resolved the relationship with the police building. The topographic jump was resolved with the parking area and volume of equipment. The deck is meant as a fifth facade as it is highly visible from all homes. He made a quick treatment courts-painted similar to sports flooring used in the development of neighboring tracks. The neighborhood center was completely open downstairs They show their public character to the street. The project is largely resolved with the repeating unit of 45m 2. End of the bars containing either or vertical communication with a second type to the facade to avoid thermal bridges in the structure. The program was arranged according to climate reconnaissance: service areas (corridors, closets maintenance, kitchen bathrooms and dressing rooms) were located on the northern fringe of the bars while all areas of ratio remained on the southern fringe. The plant layout tried to get the greatest possible internal diagonals, perceived space with its maximum length. No internal partition touch separations between dwellings. The position of the fridge partially hides the kitchen and allows the installation of a dining table. The strategic position of the terrace let slip the bedroom regard to the living room and transformed into an outdoor unit extension. The recessed geometry plant generated a deep terraces that protect the inside of excess solar radiation in summer without sacrificing the great views available to the site.
