The secret is in the unique patented corner joints that do it all. They anchor in the ground, stack on top of each other, rotate a full 360 degrees, and firmly secure the sides (use our long-lasting composite timbers, or any standard 2" x 6" lumber). It's easy for anyone to build and enjoy everything from simple garden borders to elaborate multi-level raised gardens. Choose from our all-in-one complete kits or design your own with just the pieces you need.
