My back yard is a rather large slope and I know it will take some retaining walls so I can put in a swimming pool and jacuzzi. Does anyone have any ideas on how to enclose a 20x40 ft. HEATED pool that will not break the bank? My contractor mentioned a 'tight screen material' that would let the moisture out but now lose all heat. Need some help here. I have a bad back and need to exercise in winter hopefully without taking pain meds. I need to do this. I need some advise......What do you think this will run? enclosure I mean

wow, I was hoping to get some ideas and some help here. I know that I need some retaining walls, but my biggest problem is how to enclose the pool without losing heat and so it looks decent without breaking the bank. No one has any ideas? Come on folks, this site is where all the experts are supposed to be.
