Just found this in groupon..

It's a dog kennel, not sure how big the three sizes actually are, but would certainly work as a base in a shed/run or shelter for free range in a garden.

That double kennel at the end would make a nice hutch - works out about the same as a 6' one as it's wider and I bet it would convert fairly easily.
