Here's a playhouse my husband and I are building for our children.
It is made almost entirely out of discarded shipping containers and pallets!
I just wanted to share this since it's an incredible testament not only to the vast amount of waste all around us, but also proof that with a little ingenuity and creativity it's possible to make something wonderful with almost no money involved (so far we have spent around $100 total. That was for things like nails, screws, and paint).
It's not quite finished, and I'll be sure to post an update when it is!
