In the future I am planning to build a Earth Sheltered home. Earth will surround it on 3 sides and cover the roof. The walls and roof will be concrete. The question is roughly how thick does the concrete have to be to carry the load, about 3 feet of dirt and gravel. I am just looking to ballpark this I am not building off the advice given here. I just want a general Idea.
