Google: Shipping Container HomesPretty much so. Need to weld the doors and seams shut. Best to tar it also to keep it from rotting, and as an extra layer of protection. Make acess through the roof with a guarded trap door. Also might want to consider a secondary egress. Shipping containers are cheap and very durable. Plus the steel wont burn and will contain a blast.
Here's mine...one thought with shipping containers is to put extra paint on the outside , and
on the bottom side , put tar paper , roofing felt on the sides and top .
then put about 1 ft of gravel on all side with landscaping fabric against the dirt.
and gravel under the box then build a sump pump hole on one end to pump the water out . old shingles work good on the top , then cover with dirt or concrete .
