I posted this in wofati forum, haven't heard a reply yet, but maybe the experts on natural building could point me in the right direction. Basically, a three-season structure, more comfortable than just a tent though since it gets quite cold, so I imagine some kind of heat is needed. (I saw an ad for industrial tents that said it raises the temperature 15 degrees above the outside. If the outside is 20, we're screwed.)

Thanks for any suggestions!
