Rob Roy is Director of the Earthwood Building School, which has specialized in cordwood masonry and earth-sheltered housing instruction since 1980. Rob and his wife, Jaki, have built four innovative cordwood homes for themselves since 1975, including the Earthwood home where they have lived since 1982. Earthwood is a 2400 SF two-story round, load-bearing cordwood home, earth-bermed and earth-roofed. Details of construction are in Rob's Earth-Sheltered Houses (New Society, 2006) and Cordwood Building: A Comprehensive Guide to the State of the Art (New Society, 2016) two of sixteen books he is written in the alternative building field. Rob and Jaki have taught cordwood masonry at Earthwood Building School in West Chazy, NY, all over North America, as well as in Chile, New Zealand, Australia and Hawaii. They have helped scores of owner-builders with their cordwood and earth-sheltered projects, including homes, saunas and outbuildings. Earthwood has produced a 3.25-hour DVD on cordwood construction, which, with his books, can be accessed through the Earthwood website, or on the Cordwood or Earth-Sheltered Housing pages here. Rob is considered to be one of the leaders in the fields of cordwood construction and earth sheltering. He does individual consultations at a flat rate of $75/hour, but answers questions here without charge. See also Earthwood Facebook.
