This three-story manse in Windermere's ritzy Isleworth enclave is currently on the market for over $6 million, and it looks to us like it's worth every penny. The lakefront property is slotted right in between the shoreline of Lake Butler and the 15th hole of Isleworth's golf course. The estate includes over-the-top extras like a private boat dock, a sauna, both an indoor and an outdoor pool, two game rooms, a bar, and a home theater with box office and concession stand. (If you charge your friends for popcorn and Twizzlers, this mansion pays for itself!) The house itself boasts a more contemporary aesthetic, with Mizner-inspired architecture complete with a three-story spiral staircase and marble floors with onyx inlay.
