Cordwood roundhouse home tour after living in it for about a year. Cost: 4,000 British pounds ($5,590). It look about six months work to build. Features include micro hydro power, gravity fed water, wood stove, loft and living roof.
Check out Kris Habour’s YouTube channel for all the details. He documents the entire building process, including the building of his microhydro system. I’m currently looking through his site and I have to say it looks real interesting.
