I framed mine out similar, but did it that way because I built it at home and transported it in sections and assembled it on site, so I wanted it rigid enough to be handled rough. I built an 6’ high platform, then lifted each wall up and screwed together, then built the roof on site.
Pitched the roof to the rear so rain falls off behind me, and gave it enough overhang that rain won’t come in through the windows. Roof is 2 4x8 zip panels with a sealed seam. I also shingled it.
Added a simple ladder from 2x4s and it was done. The next ladder will get 4x4 main beams with 2x4 steps.
I also used a 2x6 for a shooting rail. Simple framed windows with lexan that hinge up and lock into place. I use my gamechanger bag up on the rail and it holds my rifle for me.
We had tornados or straight line winds that snapped several trees and blew over two stands this summer. Mine held up just fine.
