Casa Bloc, an international benchmark for rationalist architecture designed by GATCPAC (Sert, Torres Clavé and Subirana), was the first social housing built in Spain in the 1930s. But the Casa Bloc project was interrupted by the Civil War and ended up as a residence for widows and orphans of the Guardia Civil, which remained active until 2015.

Currently, a foundation that manages social housing is carrying out the rehabilitation of part of the building to recover its original spirit and turn it into a refuge for people at risk of social exclusion.
