Description

A FORTRESS OF LUXURY ON ITS OWN PRIVATE POINT -- KEY COLONY BEACH Built to withstand anything nature delivers, this Mediterranean estate sits on over an acre of private point, surrounded by water on three sides. Engineered like a true hurricane shelter -- steel and poured concrete construction rated for 200mph winds, Andersen Hurricane-impact windows throughout, and a full security system -- this is a home that lets you enjoy paradise without ever worrying about the forecast. Behind that fortress strength is pure luxury. Sun-soaked stucco, soaring arches, wrought iron details, and Italian marble floors create timeless old-world elegance, while walls of windows frame turquoise water from nearly every room. A canal runs along one side, with a dock for water toys that can be extended for larger vessels. The opposite side opens to protected Vaca Cut, complete with a 25,000 lb boat lift and quick access to open ocean. Outside, a glistening pool and waterfall spa shimmer in iridescent blue tile, surrounded by deck and covered patio space built for grand-scale entertaining -- comfortably hosting 100+ guests -- with an outdoor kitchen perfect for dining as dolphins play offshore. Inside, the chef's kitchen boasts double ovens, granite counters, and top-of-the-line appliances, opening to sun-filled living and dining rooms. The main level also offers a den/bedroom, laundry, air-conditioned 2 car garage space (currently office, playroom, storage), and two finished baths. A marble staircase, lit by picture windows and trimmed in custom wrought iron, leads to a second-floor landing with sweeping views. The Master Suite delivers sunset views from bed or balcony, a spa bath with honey onyx double vanity and mosaic shower, and a custom walk-in closet. Three additional en suite bedrooms with walk-in closets complete the upper level. Storm-proof strength. Old-world soul. Resort-style luxury. Fully furnished -- just bring your bathing suit.
