Sag Harbor pool

I am looking to have an in-ground pool installed in my backyard in Sag Harbor. The area is relatively small, so the size of the pool will need to be thoughtfully considered. I am very interested in having a heated pool; this will be key for me in enjoying the pool during the cooler months. I would love to be able to wade in the comfort of warm water all year round! I am also open to any ideas you may have for additional features, however I don't feel that a pool house or slide are necessary for this project.
