This is my backyard golf swing net. It’s 10′ x 30′. Each section is 10′ x 10′. I used 2″ PVC piping for the 4 support poles with 7′ yard stakes hammered into the ground inside them. I used 1.5″ PVC pipes for the 4 poles running across the top and bottom of the structure. The rest of the structure consists of some PVC “T” pieces, elbows and adapters. You can custom this part for your specific space. Then just add some high-impact netting and you’re pretty much good to go.
