So I built the treehouse with plans from a book and after about eight years one of the support beams is bent and some of the joins have come apart. The plans called for using nails but like adumbass I used screws. It was fine until last year when I noticed this after a storm.
I can do two things. 1) get another 2x6 and put it on top of the existing support and bolt the angled support to it. Basically jack up the sagging side and double up existing support structure or 2) create another triangle support inside the existing one attached to the tree instead of the existing support.
Here are a bunch of pictures to illustrate the problem. Any advice? I’m not opposed to taking the top off and just making it a deck.
