With the possibility of a draft coming up has anyone else thought about going underground? Ive been exploring designs for an underground room/bunker in my backyard. Id start by excavating an 8x8x8 room, reinforcing floor roof and walls with rebar concrete, and waterproofing the top with plastic liners. Ventilating wiring etc can be done easily. Then id backfill the dirt and put my greenhouse on top of it to hide it.
Do any of yall have experience with this? Are there easier ways to do this?
