We've been looking at different type houses and plans for about a year now. We're planning to build on our bigger farm in the next few years, move there, and sell this place. We keep coming back to this design: http://www.thenaturalhome.com/passivesolar.html Does anyone have any experience with this company? Any possible pitfalls apparent to those of you with building experience? The house looks relatively easy to build, we have enough experience that we would probably only hire out the foundation. We would use the dry-stack method, and would probably berm it on 3 sides (with the best waterproofing we can find, money is no object as far as that goes because I'm a worry wart about leakage) to help with cooling. We like that it would mostly heat and cool itself. I keep reminding dh that it's easy to cut, haul and burn wood now, but what about 20 yrs. from now. We have a couple of springs on the place, but would probably build a rainwater collection system for our house water and use the springs for backup because the springs aren't real close to the only south-facing hillside there. Our climate is fairly warm, so we would be building the roof with an overhang over the glass, and don't know if we would need such a drastic slant to the glass. I appreciate any and all insight and advice you guys can provide! BTW - there are links under the pics that will take you to pages with more pics, possible floorplans and info.
