Baumraum = German for Treehouse

These treehouses are such a cool thing. They are one option for big backyard/small house, which we have. We want more space and wouldn't a separate building be nice? We want a prefab of some sort, but the Baumraum may be a bit elaborate. Michelle Kaufman is one of our fave prefab builders but tres $$$. Maybe a Weehouse would be more our price range? Not likely. We may have to strike out on our own. I think Readymade has building plans for one.
