The Casa Bloc is a residential building built between 1932 and 1936 in the Sant Andreu district of the city of Barcelona (Catalonia, Spain). Its architects were Josep Lluís Sert (1902–1983), Josep Torres Clavé (1906–1939) and Joan Baptista Subirana (1904–1978), all members of GATCPAC (Catalan Group of Architects and Technicians for the Progress of Contemporary Architecture). Catalan architects of the Second Republic, brought together by the GATCPAC, proposed a new way of living that was just, accommodated co-existence and defended the collective identity. The creation of Casa Bloc was one of the first steps towards dignifying workers' living conditions. As a result of the Spanish Civil war, the project was cut short. In 2012, after a careful restoration by the Institut Català del Sòl and Institut de Cultura of Barcelona through the Disseny Hub Barcelona, the doors to apartment number 1/11 are open and furnished just as its creators had originally wanted.Today, the Casa Bloc is considered a symbol of the rationalist architecture in Barcelona promoted by the Catalan Government during the Second Spanish Republic, since it was once an innovative social project, integrated in the urban environment and housing functional accommodation designed as minimum standard for workers. In 1992, the Generalitat de Catalunya declared the building as a protected heritage in the category of Monuments.
