The treehouse consists of three main platforms, we'll call them
base, lower and upper. The lower platform was the first to be built,
and was about 4'x3', and later I added a 1'x2' piece, this platform
is 15' off of the ground. The base platform was built with the intention
of some kind of stairs or ladder being built up to the lower platform.
Tip: if you are not going to live in your treehouse, don't build
stairs. I prefer an aluminum expansion ladder, but I also have this
65' fire ladder made from nylon webbing and aluminum rungs.
The Upper platform is about 7'x8' and is the newest addition.
