I had an existing deck from the rear of my house, and installed the pool about four feet from that deck. Then I went on Lowes web site, where they have a 'design your own' deck plans. It's a program where you fit in your dimensions and the style you want, and the program will set up a drawing of the deck and give an estimate of what lumber is needed and a price. My was a small rectangular access deck connecting the main deck to pool. But I built it as a floating structure that is independent of the main deck and pool. I believe Home Depot also has a design program available. Good luck!
