Under contract-accepting backup offers. The barrier island and enclave known as Casey Key offers some of the most exquisite residences along the Gulf Coast. Included in this portfolio of majestic gems includes Tweenwater, an estate aptly named as it rests between Sarasota’s Blackburn Bay and the Gulf of Mexico. From the early stages of its conception to the meticulous level of construction and finishes, not one detail was overlooked in creating this one-of-a-kind property. The entryway features a custom staircase inspired by the Harvard Club in New York City, while the formal living room is reminiscent of a true British West Indies home. For ease of entertaining, the spacious kitchen boasts ample cabinetry and flows perfectly into the dining and family rooms. A carefully curated selection of antique and new elements combines to create this exceptional residence, blending modern luxury with old-world charm. Designed to take advantage of the cross winds from beach to bay, the screened terraces transition seamlessly from the interior to the outdoors. Past the resort-like setting and infinity-edge pool await bayside boating and kayak lifts, along with 100 feet of private beachfront to the west. Rest, relax and soak up the sun or savor the endless views from the shade of a chickee hut. Fitness enthusiasts will relish the exercise, sauna, kayak and bicycle rooms. Designed by Herscoe Hajjar Architects and built by The Aerial Companies, this magnificent masterpiece provides seclusion and privacy, breathtaking beauty and luxurious quality that leaves a lasting impression. Architecturally sound, the concrete pile structure, masonry walls, Hardie Plank cement board siding, hurricane-rated windows and doors and Kynar metal roof were constructed to withstand the tests of Mother Nature, while the solar panel system utilizes energy efficiency. For peace of mind, the entire property is automated with a Crestron smart home system and Lutron lighting, integrated security and a fire detection system. An oversized 8 car climate-controlled garage and whole-house generator complete this impeccable piece of paradise. The manager has listed the unit size as 6907 square feet.
