In October, 2005, we started building a two-story treehouse in a big Sycamore. We worked with Jake Jacobsen, from the Treehouse Workshop, on the platform and finished the building ourselves.  The client was very interested in the Hobo Shack motif and so we got lots of used windows and doors and roofing. We finally finished around May, 2006 and I was still tweaking things in November, 2006.  In February, 2008 we are trying to figure oput what to do with the raccoons and squirrels that are absolutely delghted with their new home.
