This custom-built, elevated two-story estate sits on a 7,300 SF point lot at the coveted tip of Adam's Cut Waterway, with 167 feet of waterfront offering panoramic views that open directly to Largo Sound with ocean access. More than a home, it is an unparalleled opportunity to own an iconic piece of Keys history—an architecturally significant retreat built to exceptional standards of strength, beauty, and design. Spanning 3,723 SF, the 4BR/5+2BA residence features a triple-poured concrete roof, 8 inches of concrete between floors, Italian La Finestra impact windows and doors, whole-house sound system, interior elevator, Shell Reef honed limestone floors, and concealed-hinge custom doors. The main level showcases a stunning light-filled living room framed by floor-to-ceiling windows, a remote-controlled drop-down TV, stone accent wall, and sleek wet bar—all opening to the expansive wraparound terrace overlooking Adam's Cut. An open dining area complements the chef's kitchen with a backlit polished Plume Quartz waterfall island, JennAir gas cooktop, integrated refrigeration, and Liebherr wine cooler. This floor includes three bedrooms, including a junior suite with private balcony and spa-style bath, plus a designer powder room, laundry room, and two additional ensuite guest rooms. The private principal suite spans the second floor, featuring a high-pitched ceiling, midnight bar, elevated bed platform, flexible additional room, and a spa-inspired bath. It opens to a private terrace with a rooftop infinity pool, swim-up bar, and jacuzzi for a true resort experience. Ground-level highlights include a grand covered terrace w/summer kitchen, Lynx grill, salt-chlorinated pool, teak ceilings, standalone bar, and cabana bath. A hidden gem is the brick-lined, temperature-controlled 100-bottle wine cellar w/ a decanting area. A 77' private dock w/ permitting in progress for a 30,000 lb boatlift, swim platform, and sunning areas complete this extraordinary Keys masterpiece.
