Be sure that the corner posts will be high enough over the deck for the ropes. The joists sit on ledger on the beams that cross the center of the ring and the band and these beams sit on 2圆 boards that are screwed and nailed to the posts and sit on the concrete footings that the posts are set in. The joists and bands break on these posts. Essentially, we're building a 20x20 deck with 4x4 posts every 10ft. Below is the materials list and the basic plans for the ring. If you're regularly going to be sparring with folks over 220lbs, you may want to consider 5/8' plywood. Besides these items, the ring is holding up very well getting about 3hrs of work per week by 3-5 people. Delamination of treated plywood - minimized by addressing the water issues and caulking the seams between sheets. Issues we've run into are: Water pooling - partially fixed by drilling holes in plywood and lining the holes with epoxy. This ring was built during the summer of 2010 (published summer 2012) so we've had two years of use to work out the kinks. The deck is not padded, but the 1/2' plywood provides a little give.

The finished project is a 20ft deck with 16x16ft inside the ropes. With some prior experience with carpentry, it takes about three days for three people to do. Don't have $10,000 to spend on a boxing ring? Don't have a warehouse in which to fit one? For about $1,200 you can build one in your backyard.
