About this home
The most sought-after bay in all the Florida Keys, and one of the largest properties on it. This true double lot spans 1.3 acres with more than 250' of bayfront facing due west for the perfect nightly sunset. A white sand beach transitions into the clear bay waters, while a protected basin offers a 20,000 lb. lift accommodating up to a 40' boat and a 3,000 lb. skiff lift. Ultra-private, with no neighbors in sight and expansive green lawns throughout.
The home is sophisticated yet inviting, with an incredible attention to detail throughout and a distinctive blend of Tuscan Mediterranean architecture and classic Keys styling. Enter through the gates into a private courtyard and open-air atrium with freshwater ponds and fountains. An elevator provides access to the second floor, where a one-of-a-kind living room overlooks the bay with exposed wood beams and tongue-and-groove ceilings. Updated throughout while preserving its original ornate finishes, this level flows from the living and dining rooms into the kitchen with a gas range and dumbwaiter. The bayfront primary suite features an impressive bath with dual vanity areas. Two additional bedrooms share a Jack-and-Jill bath, plus a half bath finishes off the second floor.
Halfway down the main staircase is the entrance to one of the favorite rooms in the home: the library. With vaulted ceilings and a fireplace, it is the ultimate setting to work, relax with a good book, or serve as a fifth bedroom. The ground floor offers a separate ensuite guest bedroom, garage with front and rear doors, laundry room with double washers and dryers, and an outdoor kitchen.
Outside, a massive 40' x 22' pool features a hot tub and beach-entry shelf. Extensive uplighting and downlighting illuminate the property at night. An additional front lot includes a detached structure currently used as a gym and storage.
A once-in-a-lifetime opportunity to own one of Islamorada's most prized bayfront estates....
