Nestled within the exclusive North Island enclave of Marsh Landing, this extraordinary estate occupies a rare 3-acre private island setting surrounded by sweeping marsh vistas, Intracoastal views, and abundant native wildlife. Elevated approximately 15 feet above sea level, the property offers a remarkable combination of privacy, natural beauty, and convenience, just minutes from Ponte Vedra Beach, Jacksonville, shopping, dining, and golf. Designed with timeless European influence and thoughtfully updated with today's most sought-after amenities, this 5-bedroom plus office, 5.5-bath residence spans approximately 6,130 square feet of luxurious living space. Architectural details include graceful arches, upgraded millwork, pecky cypress ceilings, hand-finished masonry and stucco, flagstone accents, one-of-a-kind antique doors, and a wood-paneled elevator connecting both levels. The gourmet kitchen is equipped with Wolf and Sub-Zero appliances, a prep sink, walk-in pantry, custom hood, newly updated countertops, and new fixtures, creating an ideal space for both everyday living and entertaining. The first-floor primary suite and private office provide comfort and convenience, while upstairs features four spacious guest suites, a game room, and a balcony overlooking the surrounding landscape. Modern luxury meets effortless living through a recently installed $75,000 Savant smart-home system, allowing control of lighting, music, climate, shades, and ambiance directly from your phone. A temperature-controlled wine closet further enhances the home's exceptional entertaining capabilities. Outdoor living is equally impressive, with multiple covered patios, a spacious lanai, a newly constructed pergola, and a fenced backyard with room for a future pool. Soil testing has already been completed, and no bulkhead is required. For boating enthusiasts, a permit is in place should a future owner wish to construct a private dock. Built for longevity and peace of mind, the home features concrete block construction, hurricane-rated windows, a Spanish tile roof, and a gated entrance leading to a three-car courtyard garage with abundant storage. Whether enjoying sunrise coffee overlooking the marsh or sunset views across the Intracoastal, this is a rare opportunity to own one of Marsh Landing's most distinctive and private estate properties.
