When you think your house is a bit different, check out these! Most of them are for sale, so you have some opportunities here.
Some of these houses are the dome type made popular in the 1960s by Buckminster Fuller (the discoverer of “buckyballs”–google it). They are very energy efficient and are easy to build. The downside is that they do deteriorate after some years. I’m not sure if they are easy to repair or not. This idea could become more popular again if energy costs go through the roof, so to speak. I don’t think these dome homes have roofs exactly though. lol
