Building with Cob: A Step-by-step Guide

Cob building uses a simple mixture of clay subsoil, aggregate, straw, and water to create solid structural walls, built without shuttering or forms, on a stone plinth. This ancient practice has been used throughout Britain for centuries in fact, the material is so strong and durable that it is currently in use for forty-five thousand houses in Cornwall, a county in southern England. Building with Cob covers everything from design, planning, and siting to roofs, insulation, and floors. It is lavishly illustrated with more than three hundred inspirational color photographs. The authors have recently been commissioned to build a thirty-classroom school in England in 2006; it will be the largest new cob construction project in the Western hemisphere.
With detailed illustrations and photos, this manual features step-by-step instructions for creating cob structures. Information on natural finishes is provided, including lime plasters, renders and washes, homemade clay and casein paints, and earthen plasters. It details how to construct a cob building that complies with modern building standards, and gives guidance on restoring and repairing old cob structures. A comprehensive list of resources and suppliers is also included.
