Overview: 390 13th St

A FORTRESS OF LUXURY ON ITS OWN PRIVATE POINT

Built to withstand anything nature delivers, the luxury waterfront estate at 390 13th St, Key Colony Beach, FL 33051 sits on over an acre of private point, surrounded by ocean waters on three sides. Engineered like a true hurricane shelter — featuring steel and poured concrete construction rated for 200mph winds, Andersen Hurricane-impact windows throughout, and a comprehensive security system — this sanctuary offers complete peace of mind without compromising on tropical paradise living.

Behind that fortress strength lies pure Mediterranean elegance. Sun-soaked stucco, soaring architectural arches, wrought iron craftsmanship, and Italian marble floors create timeless old-world elegance, while expansive walls of glass frame crystal turquoise waters from nearly every room. A tranquil canal runs along one side with a private dock for water sports, while the opposite side opens directly to protected Vaca Cut, complete with a 25,000 lb boat lift and instant access to the open ocean.

Outside, a resort-style iridescent blue tile pool and heated waterfall spa shimmer under the Florida sun. Surrounded by expansive decking and covered patio spaces designed for grand-scale entertaining — comfortably hosting 100+ guests — complete with an outdoor kitchen ideal for al fresco dining as dolphins swim past your private shore.

Inside, the gourmet chef’s kitchen features double ovens, premium granite countertops, and top-of-the-line appliances, flowing seamlessly into light-filled living and dining areas. The main level also provides a flexible den/bedroom, laundry room, climate-controlled 2-car garage, and two full designer baths.

A grand marble staircase, bathed in natural light through picture windows and finished with custom ironwork, leads to a breathtaking second-floor landing. The Master Suite delivers unforgettable sunset views from bed or private balcony, a spa-inspired bath with honey onyx vanities and mosaic shower, and a custom walk-in closet. Three additional en suite bedrooms complete the upper level of this rare Florida Keys luxury listing.
