Introducing 46 Mount Grey Road, Setauket — a rare North Shore waterfront gem that redefines luxury coastal living. Set on nearly two private acres, this expanded 4-bedroom, 2.5-bath ranch is currently under renovation and being offered pre-sale, giving its next owner the exclusive opportunity to select their own custom paints and finishes before completion.
Step inside and experience the bright, open-concept design, where the kitchen, dining, and living areas flow seamlessly together. The kitchen’s oversized bay windows offer uninterrupted panoramic water views, filling the home with natural light and creating a stunning backdrop for everyday living and entertaining. Enjoy cozy evenings by the den’s fireplace or host gatherings on the brand-new rear paver patio, all while taking in breathtaking sunsets over the water.
The primary bedroom suite is a showpiece — featuring incredible water views, a private en suite spa-style bathroom, and a large pass-through closet that perfectly balances comfort and sophistication. Completing this exceptional home is a 2-car attached garage and an oversized driveway, providing plenty of parking for guests and convenience for a large family.
Please note: Some photos shown are renderings of the soon to be completed exterior design and 3D floorplans of the newly revised layout currently under construction. Additional photos of finished kitchens and bathrooms are from our client’s previous projects, meant to demonstrate the exceptional craftsmanship and quality finishes that will be delivered upon completion — not the home’s current condition.
Enjoy year-round water vistas and sunsets from this extraordinary property, perfectly situated in one of Setauket’s most desirable waterfront communities. Don’t miss this rare opportunity to customize your dream home before it’s complete — luxury waterfront living awaits at 46 Mount Grey Road.
