Don't bury a shipper. YouTube will show you why. The cost involved to make them strong enough outweighs the costs of using concrete designed to be buried. I'd be looking for a huge cylinder/tank. With a false floor similar to a passenger jet, you have a void underneath where you're services run in and out (similar above for ventilation/heating/cooling). Master bedroom at the end (deepest point). Bathroom/shower to left and toilet to right as you reverse back out, leaving a corridor to access the master bedroom, then bunks on left and right. A galley kitchen next and at the outer most end a living room with full glass front. If the tank is long enough it could form a decked entertaining area at the very front. This is also the place to have the steel shutters for when you are not there. If you want some natural light, a steel tube up to the surface above will give you plenty.
