I've never even been in a treehouse, but it seems like now they're a big hit with adults as well as kids...http://www.zillow.com/blog/treehouse-trend-151729/
Sea, I spent may hour building one as a 8 y/o, and it made for a great hideout to read. At 25, I became a Cub Scout leader, and we built a tree house 20' 0ff the ground. The inside was 30' x 30', and the local hardware store donated the scouts dark blue color. I would take the kids on Friday after school, and the parents would pick up there exhausted kid Sunday, and thank me for being a free baby sitter.
We had overactive imaginations in those days.
Can't recall every seeing one with a sauna or stained-glass windows. These were built by professionals...for adults, who never grew up. Peter Pan would have liked these!I've never even been in a treehouse, but it seems like now they're a big hit with adults as well as kids...http://www.zillow.com/blog/treehouse-trend-151729/
