A guide to the re-emergence of earthen architecture in North America, where adventurous builders are creating timeless forms such as arches, vaults and domes using inexpensive, easily available materials. Even inexperienced builders can construct a tree-free building from foundation to curved roof.
Maybe it's just because I've now read almost all the books about building with earth that the library has, but this was pretty boring. It's a very overview-y overview. There were also elements that appeared ripped off from (or had at least previously appeared in) Donald Kiffenmeyer and Kaki Hunter's book... which is by far the best book on the subject.
