I love this earthbag dome. They built it as a tool shed . Owen Geiger has the directions on how to make one of your own over on Instructables. I really like the way it looks and with that living roof it really looks like it belongs.
He says it was pretty inexpensive to make which makes me like it even more.
From the Instructable he has a link to his youtube channel where you can see the building of it. Very cool.
