I have always wanted a tree house. I still do. And why not? They aren’t just child-sized, backyard tokens anymore folks (although I wouldn’t mind one of those either). There are communities and tree-homes/getaways popping up all over the world. And there are companies that specialize in building them. One such company in Seattle, the Treehouse Workshop, specializes in building treehouses (for kids and adults) complete with electricity, and running water, which is pretty ideal if you are really going to be spending a lot of time up there.
