Two days before the trip!

And my mind is turning. Here's an alternative design idea that Matt suggested:



There are several benefits to this design over the original.

• Half again as much room in the loft
  
• The roof would be simpler and safer to build
  
• More south facing exposure
  

The downside is that the treehouse is starting to look top heavy. Since it's only hanging in place, how badly will it want to tip over? Unfortunately, it would seem that if you had a lot of weight to one side, that side would want to sink, which would raise the other side, thus making it want to tip more...
