SOOOOOOOO exciting but overwhelming!!!!!!!!!! Went to the library to get books about earth sheltered homes and the "newest" was 1980. Our home will be 32' x 56', one level not counting the garage. May do a partial earth sheltered, just 2 sides and not the roof covered with sod. Have NO idea how expensive this would be. I know water proofing and venting are two big concernes, BUT... if we build it like a basement, have earth @5' high on the outside of two walls, basement type windows ground level, garage attached to the 3rd side with long windows on the south side (4th side) and then a regular roof we are hoping the cost will not be out of our budget. We have a finished basement now with 3 sides in the ground and the temperature NEVER changes more than 7-10 degrees. Any body have plans, info, books to suggest? Anyone have ANY range of price? We are going to get with an engineer after the holidays but wanted to see if we could find a price range ( per foot, sq. foot???). HELP...Joan
