From the outside, it simply looks like a unique home.

But there's more to it.

The builder, ModEco Development, has put up a 2,250-square-foot home in the 2500 block of Rochester Road in Royal Oak comprised of recycled shipping containers, according to Ian Thibodeau of the Grand Rapids Press.

The paper writes:

ModEco partner Drake Boroja said five 40-foot containers and two 20-foot containers were used to build the house. It’s taken about a year to finish, because when they started, ModEco fabricated the shipping containers on-site in Royal Oak.

And with a few things left to wrap up, the three-bedroom, 2.5-bath home has already sold for about $430,000.
