"The first U.S. multi-family condo built of used shipping containers is slated to break ground in Detroit early next year."
There are good reasons nobody has done this before.
Among them is that despite more than a decade of attempts to to create such projects, shipping containers remain grossly ill-suited for conversion to dwellings. Their dimensions are poor for commodious habitation; they remain uninsulated, unfenestrated, and expensive to modify due to unibody construction; and in relatively short supply for the purpose.
It makes little more sense than cutting teddy bears lengthwise to make carpet slippers.
