This move-in-ready sanctuary blends timeless architecture with modern luxury, offering unmatched privacy and sweeping coastal views. A newly resurfaced driveway leads through electronic gates to beautifully lit grounds featuring a restored gazebo, lush lawns, and thoughtful landscaping. Inside, the home shines with freshly refinished hardwood floors, custom details, and a reimagined primary suite with spa-like finishes.
