Cordwood masonry is an ancient building technique whereby walls are constructed from "log ends" laid transversely in the wall. It is easy, economical, aesthetically striking, energy-efficient, and environmentally sound. Cordwood Building collects the wisdom of more than 25 of the world's best practitioners, detailing the long history of the method, and demonstrating how to build a cordwood home using the latest and most up-to-date techniques, with a special focus on building code issues. Author/editor Rob Roy has been building, researching, and teaching about cordwood masonry for 25 years and, with his wife, started Earthwood Building School in 1981. He has written 10 books on alternative building, presented four videos-including two about cordwood masonry-and has taught cordwood masonry all over the world.
