Drop me a line or check out my website: http://www.moorebettahukes.com (Click on the "MY LIFE" tab) and I'll give you da scoops. Our treehouse is about 200 sq. ft. and used as an office/ meditation room. It was built about ten years ago in a hundred year old mango tree. It's the only place on our property that we have an ocean view so that part in itself makes it worth while. Sleeping in it's great except for during cockroach season, with mango trees being a favorite habitat of the little beasts. I have to admit to doubting the wisdom of building a treehouse only during our last hurricane, Flossie, which thankfully was nothing more than a whisper.
