"The ground we walk on and grow crops in also just happens to be the most widely used building material on the planet. Civilizations throughout time have used it to create stable warm low-impact structures. The world's first skyscrapers were built of mud brick. Paul Revere Chairman Mao and Ronald Reagan all lived in earth houses at various points in their lives and several of the buildings housing Donald Judd's priceless collection at the Chinati Foundation in Marfa Texas are made of mud brick." "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."--BOOK JACKET.
