Sorry, I don't have a parts list or plans because everybody wants to do things differently, but if you contact me directly, I'll give you a link to more info that can get you on the right path.
I had the biggest potatoes I've ever had. Of course, I grew russets, which tend to be large anyway, but they did better than I expected. Plus, I grew some fingerlings and had plenty.
Be sure they at least get partial sun. Mine have started coming on in the past few days. I'm hoping for a cooler summer than last year, but it's not looking like that. So my beans may slow down after a while.
