Description

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.
