You are only limited by your imagination, I have even seen them stood on end to make a tower.
Two biggest issues I see:
1. Adding holes for windows and doors. You need someone to weld watertight frames and too many or too big of holes take away too much strength of the container.
2. CONDENSATION! The walls don't breathe and you always risk them sweating like your iced tea glass. Bad enough on the outside but catastrophic on the inside-black mold paradise. You probably need to use closed cell foam and every humidity control trick you can to prevent issues.
