We want to build a home that is mostly underground. Texas is hot and it would eliminate the need for a lot of A/C. Plus if we have 2000 feet underground and only 1000 above ground, it doesn't make our home look like anything special. We also want to put basements under all of our out buildings. The more we can keep underground and away from prying eyes, the better. We would also bury our water tanks and fuel tanks. Everything above ground would be as modest looking as possible. Solar panels would be placed lower to the ground so that people couldn't see them from the road. Stealth would be key for me.
