Hospitalet de Llobregat Social Housing

competition, 2nd prize

The proposal seeks to harmonize with the built context of the block while providing the best relationship between interior and exterior spaces. A continuous open gallery surrounds the exterior façade of the building in its whole length, directly related with every living and bedroom, displayed in a 4 meters deep modulated belt along the façade. This configuration -modular spaces with an exterior extension- provide polyvalence and flexibility to the dwellings and maximize natural light exposure and natural ventilation.

The gallery works as an extension of the rooms, generating an exterior domestic space for each, as well as a climate regulator. All the service spaces (kitchen toilets, laundry) occupy the interior belt, where a series of hexagonal patios (1 for every 4 apartments) provide natural light and crossed ventilation to each housing unit.

From the environmental sustainability and comfort perspective, the project integrates multiple passive solutions such as thermic inertia, natural cross ventilation, sun protection and natural higrothermal control and transpirabilty. The construction solution Is based on structural walls made out of lime concrete that will provide transpirability to the façades.
