Whoa... those are such cool sites - and sights!
I love the Adobe one, and the domes are cool, although a lot of those people have quite opposite tastes from me when it comes to the interiors. Golly there are so many different ways to build things and we are stuck with just one that isn't even the best! It figures...
I toured one of those domes once, I'm not sure where. Maybe Florida? It was when I was a kid. It was a model and it looked kinda like where an alien might live.
The cement guy's work is awesome. It would be nifty if someone was building a house if he could come and do one room or a hallway or stairway, etc. even if it wasn't the whole house.
