Rustic Tree Fort getting started

Hooray! Plans have been approved for me to start building a Rustic Treefort, using old logs as well as our usual redwood lumber. Here's my sketch of what we'll be making:

My brother James & I  also worked up a detailed AutoCAD site plan to compliment the sketch. That let's me verify that everything will fit.

Now James & I will start the detailed construction drawings to give to the builders, plus I have to gather some more logs for the railings.
