For two decades, the students of Auburn University’s Rural Studio have designed and built remarkable houses and community buildings for impoverished residents of Alabama’s Hale County, one of the poorest in the nation. Our critically acclaimed bestseller Rural Studio (2002) showed how salvaged lumber, bricks, discarded tires, hay and waste cardboard bales, concrete rubble, coloured bottles, carpet tiles and old license plates have been transformed into inexpensive buildings that are also models of sustainable architecture. Rural Studio at Twenty chronicles the evolution of the legendary program, founded by MacArthur Genius Grant and AIA Gold Medalwinner Samuel Mockbee and showcases an impressive portfolio of projects. Part monograph, part handbook and part manifesto, Rural Studio at Twenty is a must read for any architect, community advocate, professor or student as a model for engaging place through design.
