The Niwot Treehouse - Niwot, CO

This elevated playhouse keeps the feeling of a treehouse, without using any trees for support (they were too small!)  A curving deck with a natural stick rail wraps around the front on the tree side, and the house is oriented to take advantage of the view of Longs Peak straight out the back window.  The fun here is rounded out by a giant web swing we hung in a massive cottonwood that overhangs the back yard!
