Offering nearly 3,000 square feet of living space, this four-bedroom, three-bath residence captures panoramic water views with breathtaking sunrises over the ocean and spectacular sunsets across Moriches Bay. The second level is dedicated to open-concept living and designed to maximize the home's unparalleled setting. The living room, dining area, and kitchen flow seamlessly together beneath walls of glass, while three sets of sliding doors open to an expansive oceanside deck overlooking the beach and Atlantic beyond. A partitioned office provides an inspiring workspace framed by endless ocean views. The second floor primary suite offers a commanding ocean view, gas fireplace, direct access to the oceanside deck, and a spacious ensuite bath featuring dual vanities, bidet, and oversized shower with dual shower heads.

Two bedrooms share a hall bath, while a separate guest suite enjoys its own private entrance and ensuite bath, which also serves as a convenient pool bath. Outside, resort-style amenities include a heated, oceanside pool -- complete with full swim lane and diving board -- outdoor shower, expansive decking, and a private walkway leading directly to the ocean beach. A two-car garage and oversized driveway provide ample parking for all. Thoughtfully maintained, the property features solar panels for energy efficiency, a 2019 roof, numerous newer window installations within the last five years, a new pool heater (2025), new pool pump (2026), and a pool liner approximately five years old.
