A view out the back windows.  Each window section is 4' wide.
These sections were put together up in the treehouse.  The first set I put
together on the ground and lifted them up in place.

I did remove many of the branches as you can see in this pic.  Most at this level however (on a pine)
were dead.  On pine trees it's only the outer layer that grows and is green.  There were a few bigger ones
but I did try and leave as many of  those as possible.

Just starting the roof.  Here you can get some idea of the tree sizes.
