We put in an above-ground pool a couple of years ago. With the assistance of my BIL and SIL, we built the deck to go around a section of the pool, and butt up to the screened in porch. The section that comes directly off the porch measures abut 11'x11', and the steps up to the rest of the deck that is level with the top of the pool. Full size, it measures 30'x30', and the decking is 2x6 PT treated boards. These pics are prior to putting on a stain/sealer, which was done after the boards had a couple of weeks to dry out some. The last pic was from the roof, after we had closed up the pool for the season.
