A community-focused residential building harmonizing urban life with nature.

Edificio 111 stands as a significant architectural achievement in Terrassa, Barcelona, offering 111 social dwellings that seamlessly integrate with the surrounding landscape. Located at the eastern limits of the city, the building faces an expansive natural park characterized by pine trees and dry streams, creating a unique dialogue between urban and natural environments.

The design revolves around a central semi-public square that acts as the heart of the building. This communal space serves as a welcoming entry point for residents, fostering interaction and connection among the inhabitants. It is thoughtfully designed to dissolve the boundaries between public and private realms, allowing for a progressive transition from the street to the home.

The interiors are characterized by a fluid spatial arrangement, with minimal closures to enhance connectivity. Each dwelling features a continuous flow of spaces, allowing for cross-ventilation and views toward the entrance courtyard and the nearby forest. The project emphasizes outdoor extensions such as terraces, balconies, and ground-floor halls, which provide additional living space and enhance the residents' experience.

Natural light is a critical element in the design, particularly in the underground parking area, where strategically placed openings in the central square offer glimpses of greenery and enhance ventilation. Three acacia trees, planted at the lowest level, grow upward, visually linking the various levels of the building.

The façade of Edificio 111 is a standout feature, crafted from in-situ concrete that reflects the texture and imperfections of the surrounding landscape. This design choice not only creates a striking visual identity but also allows the building to be perceived differently depending on the viewer's distance. From afar, it appears as a cohesive unit, while up close, the textured surface invites interaction and engagement.

In essence, Edificio 111 is a testament to the potential of social housing to foster community and connection while respecting and enhancing its natural surroundings.
