La Bertrana

The project is a cooperative housing development under a use-transfer model, promoted by Sostre Cívic, which takes on the challenge of building a new residential building in a short time. For this reason, a prefabricated concrete structure is chosen from the outset to speed up the construction process. The building includes a total of 60 housing units, a parking area, a municipal facility, and community spaces, all designed to foster coexistence and strengthen the connection with the surrounding environment.

In volumetric terms, the building is composed of a ground floor that houses a 500 m² municipal facility, as well as access points and a multipurpose room. Above this base rise two volumes intended for housing and communal spaces, with heights of 3, 7, and 3 storeys. The dwellings are organized around vertical circulation cores starting from the ground floor and are accessed via exterior walkways facing south. Regarding parking, 50% of the spaces required by local regulations (POUM) are provided, and areas are reserved for bicycles, promoting more sustainable mobility.

The project places special emphasis on urban integration and relationship with the context. The volume is compacted and aligned with the street to define the perimeter, while stepping back from the nearby school to reduce its impact. In addition, public space extends into the building through a covered passage that connects the park to the rear courtyard, which becomes a natural extension of the communal area. Outdoor circulation is prioritized through open walkways that encourage contact with the exterior and reduce energy consumption. The exterior spaces of the ground, first, and fourth floors are connected, supporting community life.

In terms of social interaction, the project combines a large ground floor with smaller spaces distributed throughout the building to create varying degrees of social engagement. Visual and physical connections link elements such as the street, parking, courtyard, terraces, and main lobby, promoting spatial continuity. Furthermore, the project ensures universal accessibility, taking into account children, older people, and those with functional diversity. From a construction standpoint, a prefabricated concrete structure with hollow-core slabs is planned, along with lightweight timber-frame façades with prefabricated insulation, helping to reduce environmental impact and speed up construction.
