Property Description
The Ultimate Keys Compound: A Shelter Bay Masterpiece Welcome to your dream home in Key Colony Beach. Perched on a premier 0.39-acre point lot, 781 9th Street offers an unparalleled 276 feet of deep-water frontage, making it a crown jewel for serious offshore anglers and sunset seekers alike. Step inside to an airy, open-concept sanctuary where the line between indoors and outdoors disappears. Take the elevator to the gourmet kitchen which serves as the heart of the home, featuring premium appliances, island, and abundant cabinetry space, perfect for hosting aprés-sea gatherings. The master suite is a private retreat with direct access to the wraparound balcony with amazing westward views and a spa-like ensuite bathroom featuring a jetted tub and a separate walk-in shower. The exterior is designed for the ''Keys Life'' at its most vibrant. Whether you're launching a world-class fishing expedition from your 55-foot cut-in slip or enjoying a ''staycation'' by the resort-style pool, the amenities are endless. Kids and adults alike will love the 9-foot deep pool with its own waterslide and splash pad. As the sun sets over Shelter Bay, move to the outdoor kitchen and bar to grill your fresh catch while catching the game on the outdoor TV and enjoying a beautiful Keys Sunset within view to the west. Located in the prestigious Key Colony Beach community, you are just a short boat ride (5 miles) from the iconic Sombrero Light and world-class diving. Enjoy the amenities of KCB, a marina, parks, shops, restaurants, tennis courts, and nearby golf, all while maintaining the seclusion of a private gated, point-lot estate. Large vessels are no problem here with a deep water 55x24 protected slip, and additional boat lift and all the seawall you could want for multiple water toys! Draft is no problem for larger vessels.
