Santiago Cirugeda is a subversive architect from Seville who has dedicated his career to reclaiming urban spaces for the public. In austerity-hit Spain where the state has retreated and around 500,000 new buildings lie empty, "people are doing things their own way," says Cirugeda. "In times of crisis, people come together to find collective solutions." We follow him as he takes on his biggest task yet, saving a huge abandoned cement factory, and negotiating with the authorities to let his National Architects' Collective turn it into a vibrant cultural centre.
