Art installation treehouses/treehuts (locale unknown) from the site ifeelasphalt.com
They don't appear very large (see the museum's bench in the right of the photo...), but are certainly unique, if not a little chaotic too. Very fun....from the mind of Tadashi Kawamata.
More updates, and photos- soon- on the next treehouse/tiny house/hut I've been building too...
