Shipping container homes are all the rage with the millennials right now. I have two friends that are building homes with them they are booked solid until this time next year. I’m thinking of digging up space for one or two and covering them with dirt so as to have an underground man cave set up.
Just don’t put the dirt on the container itself! Them bad boys been known to buckle under dirt. I’d drop a few several feet underground, encased in a concrete barrier/box, with walls say, 3 - 4 foot thick? Maybe a nice ventilation system? :D
