Meticulously crafted by D'asign Source, this custom home boasts an unparalleled blend of sophistication, comfort, and functionality while also offering some of the best deep-water boating in the Keys from 110' of canal frontage and rare deeded canal bottom. Upon arrival, the estate captivates with its generous private lot and meticulously manicured flora. Renovated to perfection in 2024, the main house and new addition guest house seamlessly integrate modern amenities with tasteful seaside decor. Inside, the spacious open floor plan and towering cathedral ceilings give way to a wall of windows overlooking a generous deck and pool below. A gourmet kitchen is outfitted with top-of-the-line Sub Zero, Wolf, and Miele appliances, quartz countertops, and a walk-in pantry, and a 450-bottle walk-in wine closet with independent climate control caters to the discerning oenophile. After dining, retreat to the primary suite, where a balcony offers breathtaking views of the tranquil pool deck and canal below. Enjoy expansive outdoor living spaces, where a heated and chilled saltwater pool awaits alongside an aptly outfitted outdoor kitchen, providing the perfect setting for alfresco dining and soirées under the stars. 80' of new dockage with dolphin cluster pilings to accommodate up to a 90' yacht plus a new 20K pound lift all on a 200' wide canal with 6' control depth yields unrivaled large vessel access to both the Atlantic Ocean or the Gulf. An outdoor shower provides a refreshing respite after a day on the water. 3 separate garages afford parking in excess of 4 vehicles, and storage for an abundance of toys and tools. 45 KW Generator to power the entire house with 1,000 gallon propane tank. Owner occupied and never rented this Coco Plum Estate offers a rare opportunity to indulge in the quintessential Florida Keys Lifestyle.
