What's special

Escape to ''The Castle'', a luxurious gated Gulf-front estate rarely spanning 1.14 acres on Big Pine Key. This extraordinary retreat is a graceful blend of architectural grandeur and coastal charm, thoughtfully designed for both relaxation and recreation. Boaters will delight in an unparalleled offering of 235 feet of dockage total: 140 feet of protected canal-front dockage featuring a 15,000 lb lift, cut-in slip, boat ramp, plus a 95-foot open water pier-style dock with additional 15,000 lb lift and cut-in slip, set against a 130-foot concrete seawall for secure, convenient access. Crafted in 2014 with solid poured concrete, impact-rated windows and doors, whole home generator and elevator, the home is built for enduring elegance. With over 4,600 square feet of refined interior space, this 3-bedroom, 3-bathroom estate is an architect's masterpiece with its stately presence, curved openings, and striking double staircase. Step inside to a breathtaking panorama of endless open Gulf waters and nightly sunset performances. The chef's kitchen is a dream for entertaining, featuring 10.5-foot island with seating for 8, dual sinks, refrigerators, and ovens, plus Jenn-Air 6-burner gas cooktop with pot filler, and rich wood cabinetry. Enjoy the grand family room with Gulf views, host movie nights in the private theater, or dine al-fresco under the stars. Nearby, find the full-size laundry room and storage. The top-floor primary suite is a sanctuary, offering sweeping water views, home office, private lounge with kitchenette, spa-like bath with clawfoot tub, tiled shower and generous walk-in closet with additional laundry. Outside, the resort-style pool beckons with a spa, water features, LED lighting, plus heater and chiller. Rooftop deck with 180-degree views, and unrivaled sunsets await. Offered fully furnished, this is ultimate Keys living without compromise!
