About this property
Welcome to Lion's Gate on the Sound, a premier waterfront estate set on over 3 private, gated acres along the Long Island Sound in Mattituck. 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. Smart-home automation, new TVs, and elegant upgrades enhance everyday living. The finished lower level offers a professional gym, billiard room, and custom bar, while the upgraded garage with epoxy floors and smart tech is ideal for car enthusiasts. Outdoors, enjoy a new dining pavilion, full irrigation, and multiple vantage points for stunning sunsets over the Sound. Perfectly located near vineyards, farm stands, and charming village life, Lion's Gate on the Sound is more than a home, it's a legacy estate of luxury, seclusion, and natural beauty. Pool permit pending.
