Along the road to Grand Canyon, there stand many a six-sided or eight-sided wooden house. They are called "Hogan", the traditional house of Navajo people.
International Wood Culture Society (IWCS) is a non-profit, non-governmental international network of wood enthusiasts, dedicated to the research, education and promotion of wood culture.
Hermia say: A very high-quality video on wood house. Interesting to have found the website :D
