If you are not a do-it-yourself kind of person I would budget 200k. Keep in mind regarding pools, a rectangular shape will get you more bang for your buck and a more user friendly pool. The irregular shapes cost most, yet they can look pretty fancy. The pool guys will try to sell you on rock slides, grotto’s, etc..think twice if they are really needed. I have 3/4 of an acre, doing the majority of work myself. With a 20 x 40 pool with spa, covered patio with outdoor bathroom, 2,700+ sq. ft. of pavers, flagstone entry path, 25 x 65 grass play area, landscaping plants/trees, drainage, etc, etc…I’m looking at 130k. If you can’t do it yourself and/or manage it yourself, be prepared to pay. When the landscape contractor drives into your neighborhood, he will see dollar signs $$$. Good luck
