One or more photo(s) has been virtually staged. A masterwork of coastal positioning, this landmark waterfront estate represents one of the most commanding geographical opportunities on Lemon Bay. Situated at the direct termination of an ultra-private cul-de-sac, this one-of-a-kind sanctuary is surrounded by water in nearly every direction, offering an unrepeatable coastal footprint where absolute privacy meets true deep-water luxury. For the yachting enthusiast or discerning land collector, the property features a massive seawall and immediate sailboat-water access with no fixed bridges to the open Gulf via Stump Pass. Strategic re-engineering options for the expansive seawall allow for vessels ranging from 50 to 100 feet, making it a rare sanctuary for elite maritime craft. Spanning an impressive 4,937 sq ft under air across a meticulously designed multi-level layout, this 5-bedroom, 4.5-bathroom estate effortlessly frames sweeping, panoramic water views from nearly every room. An internal elevator services every level from the ground floor up to the third-story observation suite. The main living level features soaring 10 and 12-ft ceilings, a gas fireplace framed by rich travertine, and extensive custom built-ins. The gourmet culinary space flows seamlessly into the dining area and features custom cherry wood cabinetry, solid core wood doors, premium granite countertops, a large entertaining island, and a Thermador gas range. The layout provides unmatched flexibility for multi-generational living or a corporate retreat. Four bedrooms sit on the main living floor, including two comprehensive en-suites. The primary suite serves as a private oasis with French door balcony access, custom walk-in closet, and a spa-like bath with dual showerheads. The top floor functions as an elite entertaining or bonus living space, complete with a wet bar, wine storage, refrigeration, and French doors leading to a private open wraparound balcony with bird's-eye views across the Intracoastal, canal, and distant Gulf horizon. The ground level serves as a private, fully air-conditioned retreat (featuring 729 sq ft of nonconforming space) with a dedicated living area, bedroom, and full bath that opens directly to a resort-style screened pool and spa with premium paver decking and exceptional ceiling height. Beyond its premier location, the property delivers unmatched structural peace of mind and substantial recent capital improvements, including a new metal roof (April 2024), full interior and exterior paint (Nov 2024), three high-efficiency HVAC systems (replaced 2023), a pool heat pump (April 2020), a whole-house water filtration and softening system, a comprehensive security infrastructure, and full hurricane impact windows and doors with additional shutter protection. Wrapped in extensive Trex decking for effortless indoor-outdoor connectivity, this estate stands ready for its next legacy chapter. Whether looking to dock a major vessel or acquire a highly secure, private peninsula layout, this is an immediate, high-value asset opportunity.
