About this home

A rare opportunity to own brand-new direct waterfront construction with private beach access and sweeping views of the Long Island Sound in the heart of Bayville. Perched atop a bluff overlooking the water, this exceptional residence offers the perfect blend of coastal living and modern luxury. Featuring 4 bedrooms and 3.5 bathrooms, the home is thoughtfully designed with an open-concept layout and abundant natural light throughout. The expansive family room is anchored by a gas fireplace and opens through sliding glass doors to the backyard, where breathtaking water views create a stunning backdrop for everyday living and entertaining. The beautifully appointed eat-in kitchen flows seamlessly into the main living spaces, while the private bedroom suites offer their own tranquil retreats. Private balconies off the bedrooms capture panoramic, crystal-clear views of the Long Island Sound, stretching to the Connecticut shoreline and all the way to the New York City skyline. From spectacular sunrises over the water to the twinkling lights of the city in the distance, the views are nothing short of extraordinary. Additional highlights include a 2-car garage, a full basement with high ceilings offering endless possibilities, and direct access to a private beach just steps away. Set within the highly regarded Locust Valley School District, this is a truly unique opportunity to own brand-new waterfront construction and experience coastal living at its finest.
