Description
Introducing Blue Water Lagoon Estate! Experience unmatched privacy and exceptional waterfront living at this gated 2.33-acre oceanfront estate in exclusive Sugarloaf Beach — a location famously featured in the film ''True Lies''. Designed for the avid boater and those seeking a resort-style lifestyle, this 5,208 sq. ft. residence offers rare amenities and direct access to world-class fishing and diving.
A protected 6-boat basin with room for extra boats is the centerpiece of the waterfront, complete with 25K and 16K lifts, a boat ramp, sandy beach, lookout point, and composite observation deck. After a day on the water, unwind in the lagoon-style saltwater pool with heater, chiller, and custom water features. The expansive tiki bar includes TVs, True refrigerator/freezer drawers, and an ice machine—perfect for effortless outdoor entertaining. Additional features include a firepit, private sandy beach, and a full outdoor kitchen equipped with built-in BBQ, Viking appliances, and True refrigeration.
The upper level offers a bright and open Great Room with sweeping ocean views, a spacious dining area, and a chef's kitchen with stainless appliances. Two covered verandas provide ideal spaces for taking in the breezes and panoramic vistas. The primary suite features an office, en suite bath, walk-in closet with laundry, sunroom, and loft. Two additional upstairs guest rooms comfortably accommodate visitors, while the separate downstairs living area offers three more guest bedrooms for privacy and flexibility.
Designed for hosting and convenience, the home is equipped with a Sonos sound system, property-wide Wi-Fi, abundant storage, a two-car garage with fishing lockers, and generous parking along a winding paver driveway. Lush, mature landscaping surrounds the property, creating a serene and secluded Sugarloaf Key retreat.
