A round house built with a spiralling roof and a stone basement.
An idea for an alternative to a concrete foundation.
There was a review in the the book review section of the magazine about Builders Guide to Solar Construction by Rick Schwolsky. I don't have it yet, but I think I would like to. They also recommended the Passive Solar Design Handbook, Volumes 2 and 3 (sorry, no Amazon link for these so far).
