About This Property
Escape to “The Castle”, a luxurious gated Gulf-front estate spanning 1.14 acres on Big Pine Key. Built in 2014 with poured concrete, impact windows/doors, elevator, and generator, this 4,600+ sq. ft. masterpiece offers 3 bedrooms, 3 baths, and breathtaking Gulf views. Boaters enjoy 235’ of dockage: 140’ protected canal dock with lift, ramp, and slip, plus 95’ open-water pier dock with lift and seawall. Inside, a chef’s kitchen with 10.5’ island, dual sinks, Jenn-Air gas range, and wood cabinetry flows to a grand family room, theater, and rooftop deck. The top-floor primary suite boasts water views, office, lounge, spa bath, and custom closet. Outside, a resort-style pool with spa, heater/chiller, and LED lighting completes this rare Florida Keys retreat.
