Ultimately the appeal of a shipping container comes down to flexibility. The list of things you can’t do with one is shorter than the list of things you can do with it, because it’s just a box. And since it’s just a box, it can be made into just about anything. You can have windows and electricity added. Have it insulated and refrigerated for storing food, or add roll-up doors to create a garage. Just about anything you can do with a conventional building, you can do with a shipping container, and without having to pay skyrocketing lumber prices.
