Planning a shop build, any suggestions?

Hah! I got no idea what you are referring to as I most certainly dropped my sister before I married my cousin!
Virtually most every structure around here is some variation of a pole barn. Keep in mind we are in a heavy Ag community. We are looking at burying a twenty ft shipping container in side of our mountain for tornado events. Not to derail thread but do any of you have experience with shipping containers as shelter? If so PM me so as not to derail thread.

The thing you have to watch on burying a shipping container is that the side walls will collapse inward if you do not reinforce them before putting the fill back in around them. The other thing is those wood floors are treated to resist salt water and insects and what have you. So technically speaking you would want to get a new container that has not had the wood floors treated yet so that you would be able to breathe without taking in harmful chemicals.
