Currently it is estimated that one half of the world’s population—approximately three billion people on six continents—lives or works in buildings constructed of earth. And while the vast legacy of traditional and vernacular earthen construction has been widely discussed, little attention has been paid to the contemporary tradition of earth architecture. Author Ronald Rael, founder of Eartharchitecture.org provides a history of building with earth in the modern era, focusing particularly on projects constructed in the last few decades that use rammed earth, mud brick, compressed earth, cob, and several other interesting techniques. EARTH ARCHITECTURE presents a selection of more than 40 projects that exemplify new, creative uses of the oldest building material on the planet.
