Large planter with a bench around the top. The inside dimensions are 32" (l) x 32" (w) x 22" (h) . The planter's exterior dimensions are 36" (l) x 36" (w) x 27" (h). I needed a large outdoor planter for my hops vine. They want soil at least 22" across and 20" deep. I started with those dimensions but it grew as I tried to minimize the scrap wood. Since the opening is substantially larger than 22", I added a bench around the top. It reduced the opening, but not too much. I fastened it mostly with pocket screws except for one entire side. I fastened that side from the exterior so I can unscrew it, open the planter, and clean it out. I'm very novice at designing and at woodworking. I'm positive it's been over designed, and that the project will go faster for you. I uploaded my project notes as an image, but it cuts off the border to all my photos. It also won't save the wood under materials so here: 1x6x12' cedar - 5 planks 2x2x8' cedar - 1 plank 2x4x12' cedar - 2 planks 4x4x8' cedar - 2 planks In hindsight, I'd replace the 4x4's with 2x4's. One 2x4 for each center support, and two 2x4's fastened in an "L" shape for each corner support. It would save money, and it would be easier to cut (my circular saw couldn't cut all the way through the 4x4's in one pass).
