My buddy Steve from Cypress Lake kennel are build new above grounds. We are building them with 1.5 inch angle and horse panels. We are using the plastic Dura Bench Ultra for the floors and 5/4 board treated for the porch. This double weights abought 250 pounds so it can be moved pretty easy by two guys. We are also going to mount wheels on adjustable legs so you can adjust to level on uneven ground. Hope to have it finished next week depending on how many ball games the kids have. Haha
