Located within the prestigious Marsh Landing Country Club, this exceptional custom estate on Harbour View Drive has been extensively reimagined with nearly half a million dollars in thoughtful, high-end improvements -- a true testament to craftsmanship, design, and luxury living. The current owners spared no expense, creating a residence that seamlessly blends timeless elegance with modern comfort and functionality. A private courtyard anchored by a tranquil fountain creates a breathtaking first impression and serves as the heart of the home -- an inviting space designed for both intimate relaxation and sophisticated entertaining. Inside, refined finishes, expansive living areas, and abundant natural light enhance every room, while the thoughtfully designed floor plan offers both elegance and everyday livability. The luxurious primary suite is a true private retreat, highlighted by an extraordinary new ~ 800-sq ft addition featuring a designer dressing room/closet, dedicated office, and flexible bonus space. Over $250,000 was invested in this addition alone, delivering a level of luxury rarely found in the community. Additional highlights include a custom-designed "super garage" with a lift, extensive storage solutions, and commercial-grade refrigerator and freezer, ideal for car enthusiasts, hobbyists, or those seeking exceptional functionality. A new HVAC unit adds further peace of mind and efficiency. Perfectly positioned with potential for navigable water access from the backyard, this remarkable property offers peaceful surroundings, exceptional privacy, and the unparalleled lifestyle of one of Ponte Vedra Beach's most sought-after gated country club communities.
