This book demonstrates the potential of these modes of construction by analysing the 40 finalist buildings for the TERRAFIBRA Award, the world’s first prize for contemporary architecture built with raw earth and plant fibres. Organised by technique (pisé, clay-based concrete, cob, adobe, pressed earth block, and plaster) or the material used (hemp, straw, reed, and bamboo), the projects testify to the commitment of these pioneering teams of architects, engineers, builders, and clients. They prove that we can build in a different way, by relying on local resources and know-how, without forsaking innovation. Rooted in a very specific sense of place, these frugal and creative architectures reveal the new horizons that await the world of construction and renovation.
