Floor is 2X4 pressure treated, with 3/4" plywood sitting on 3 mil plastic. Primed and painted with ( RESTORE new kind of paint w/ sand in it ). Car port has open sides, this has all sides covered. The framing seems real strong. Can't figure where to place the poles for the dancers. Got the garage on sale for $219. reg=279. $300. for the floor. Costly but it'll keep the crap off one car and less lawn to mow I should get it finished next week.
