I want to say that I have lived in two of Coperthwaite's yurts and helped build another. I love this design. The angle of the walls is perfect and while there is a bit of math involved, the basic building is pretty simple.
The concentric affords privacy in the outer ring that we never dreamed possible in that small a space. If you want to build this keep reaching out as you have questions. It is worth it!
