Righting the wrong

It's never going to be perfect. The platform was level, the wall was plumb... but then the knee brace began to sink (a bit), and the wall started to tilt. While it's not a structural problem, all the angles and distances go off, and you're left trying to compensate with the siding, roof, trim, etc. What to do? The solution ended up being "racking" the wall back to near-plumb and keeping it there with a screwed in 2x4 (in the photo). Great idea by Andrei (my niece's husband), who with my brother-in-law Don, helped with the solution. Once all the walls were up and screwed together, the fix held. Now the brace is off, and the platform is still a bit dippy at the furthest corner. There's accumulated water with every rainstorm, but now I got the roof and siding up. It's manageable and in the end, you can barely tell without rolling a marble across the floor ;) With treehouse construction, you learn a little flexibility - not a bad lesson in life....
