Hi Everyone,We have a small brick patio in our city "back yard" wedged between the back of our house and a wall (a little over 7'6" wide). I decided I wanted to make a custom "free-standing" U-shaped booth for sitting around a ~4' square table.My main wish list items are:Long lasting (didn't want to have to replace for at least a few yearsUnder Seat StorageLow maintenance (I'm leaning towards trex or similar for the "skin")I was working in SketchUp and got to a point where I could hopefully show someone else what's going on in my mind. I've only included one back piece so far, but ultimately the bench will have a back that wraps around as well. While I've done some simple "2x4 technology" projects including our trash hutch, I had a few questions for this build that I hope you might be able to chime in on:Does every piece of the skeleton need to be pressure-treated lumber? or would it suffice to use pressure treated for anything that touches the brick? The bench will be at the highest point of the patio, so I'm not too worried about pooling water. Just curious.Would it be sufficient to attach the 2x4's that support the "back" of the seat with a kreg jig? There's not a ton of risk of catastrophic failure if someone leans back, since it's surrounded by walls on all sides, but I still wonder if there's a better way to attach the supports for the back to the base of the bench.What kind of cross-beam support would I need on the benches (similar to the "back/bottom") of the U? Feels like I might need something on the sides about half way back, but I'm wondering if I can build this into the "lid" of the box so that when it's closed it's resting on a support piece.What am I missing or what could I do better? I sort of cobbled together a bunch of different DIYs from the web, but I'd love to hear your input on changing things around.Thank you so much for your input!\"Bones\" of the bench.
