Short description
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 centuriesain 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.
Long description
The ancient method of cob building uses a simple mixture of clay sub-soil, aggregate, straw and water to create solid structural walls built without shuttering or forms, onto a stone plinth. It is now undergoing a renaissance as an 'eco-friendly' building material because of its amazing 'green' credentials. Building with Cob shows how to apply this ancient technique in a wide variety of contemporary situations, covering everything from design and siting, mixing, building walls, fireplaces, ovens and floors, lime and other natural finishes, and gaining planning permission and building regulation approval. It also explains in detail how to sensitively restore an old cob structure. This book is a step-by-step guide, lavishly illustrated with over 300 colour photos and 85 diagrams.
