My question is which is better to build the deck level with the top rail of the pool, under the top rail or edge of the pool, or over the top of the pool edge? My husband and I keep debating on what to do. When I had an AG pool before several years ago, my oldest son bent the top rail of the pool when he jumped off the edge (the deck edge was built under the top rail of the pool). We want to have room to put a cover on it for the fall/winter, too. We are not going all the way around, just a portion big enough for patio furniture, etc.
