ESSENTIAL COB CONSTRUCTION

Cob — a mix of clay, sand, and straw — is one of the most popular and well-known natural building methods. Yet cob is often difficult to permit and can be used in inappropriate ways due to a lack of sound engineering and design information. Recent research and a newly developed building code promise to make cob building more accessible than ever. Essential Cob Construction sets the new standard for cob construction. Incorporating rigorous, up-to-date engineering and building science and decades of practical lessons learned, coverage includes: Appropriate use of cob in different climates and contexts Thermal performance and moisture management Structural and architectural design considerations, including fire and earthquake resistance data from extensive laboratory testing Hands-on cob construction, including mix design, testing, manual and mechanical mixing, wall building, strong connections with foundations, roofs, and other structural elements, and finishing options Building code d
