building it ain't much just the rat wall was a Bitch. Just my opinion, Gl.
I built an 8x12 a few years ago. No rat wall, I just sunk pressure treated 12x12 timbers into the ground, leveled them off and built off that. The whole thing cost me about 700 bucks. It was cheaper to use inexpensive plywood for the walls and use siding instead of nice plywood and paint, and its maintenance free. It's still in great shape 6 years later. I don't have any pics tho.
No need for a ratwall on anything under 200 sft.
