A skateboarding school in Kabul, a cinema in Jenin, murals in the favelas of Rio de Janeiro, a garden in Paris and a museum in Japan – what difference do such projects make to the daily lives of the people who use them? Lukas Feireiss has brought together about 30 examples from five continents to literally present the proof of the ways architecture can transform our everyday surroundings. The major social and sociopolitical themes of today call for innovative solutions. The 200-plus pages of Testify! The Consequences of Architecture showcase a new approach in architecture, urbanism and other creative urban practices at the start of the twenty-first century.
