If you'll notice the corners, there's a 2x2 raised enough to allow the one below it to slip into the slot. The wood, excepting the treated 2x2 corner, is all old growth redwood that came from a job I was on, they were actually sending this stuff to the dump. It is all 7 1/2" x 1"(a solid inch thick) and I used little cross members to not only reinforce the corners but also to hold them 1" apart for air in/water out. When I first built them I painted a red X thinking I might need to have them marked for stacking but they turned out close enough they'll stack in any order or any direction. I also used liberal amounts of exterior glue.
You could probably use treated wood instead for the sides
