Renowned French conceptualist Yves Klein (1928-1962) produced a prescient body of work concerning the concept of air architecture – an immaterial architecture. From 1957 to 1962, Klein developed “Air Architecture,” a visionary project of living environments designed to reconnect people with the Earth and its elements. This concept represents an architecture that engages climate at the origin of its design process, with the ultimate goal of radically transforming society.
