Hi I just saw your blog with the dome. I live on the border of MN and WI outside the twin cities, but I am heading North to superior or duluth area soon. I am building my own home (adobe or earthbag) and am interested in your dome idea. But as a thought have you considered installing a small home-made wood burner inside the dome for winter? You could keep your temp at summer ranges all winter.
For the exterior did you use the plastic sheets or glass and how did you frame it? Did you get a design from online? I work construction so just curious where you got the dome plans from.
In the winter, what do you grow in your dome?
Thanks for your time
