I remember reading about cordwood construction in Mother Earth news about a hundred years ago. If you had a ready source of cordwood this would be a reasonably cheap way to build. As with cob(mud and straw) building,(see post of 3/6/09) it would be quite labor intensive,especially since for aesthetics, I should think you would have to cut all the pieces the same length. You would have to cut down a lot more trees than for a cob building. Think how much simpler life would be without a mortgage. How delightful to live in a house you built yourself.
The Color Is From Bottles Set In The Mortar
