amazing treehouse, step by step. very cool but I think I would make the ladder on the interior... or possibly not have a ground floor at all, it kinda takes away from the whole "being up in a tree" experience. :] Would it be socially unacceptable for a 20 something woman to build a tree house... for herself?
Awesome backyard work/play area! Built by British design gurus Wayne and Geraldine Hemingway, of Red or Dead fame, in Middlesex, UK. The teepee is made from reclaimed wood (including old British Telecom telegraph poles) and features a communal desk on the ground floor with seating set into the decking.
