THE AVIARY TREE HOUSE, Dallas

We don't always get to design every little piece of a home, even down to the kid's tree house, but when we do, it's memorable. Conceived as an Aviary in the trees, a place for the children to create their own nest, and get away, this three level space is safe and fun. Features include panoramic views of flight paths and, of course, a zip line from the second level across the yard.
