Sunset Beach - A Private Coastal Retreat on Long Island Sound. Step from your backyard into the pristine waters of the Sound — where coastal luxury meets everyday living. Welcome to Sunset Beach, an enchanting 10-room brick estate nestled on five private, fully fenced acres along one of Long Island’s most coveted waterfronts. From jet skiing and paddle boarding to horseback riding along the shore at sunset, this is a lifestyle few can imagine — and even fewer can call their own. This expansive home features six bedrooms and seven-and-a-half baths, with grand indoor and outdoor spaces designed for both entertaining and serene daily living. The first floor opens with a dramatic foyer and direct water views, an elegant living room and cozy den sharing a double-sided fireplace, a formal dining room, and a eat-in kitchen. A stylish floating staircase leads upstairs, while a powder room, laundry room, and maids’ quarters with private bath offer practicality and privacy. On the second floor, you'll find five bedrooms, including two suites with marble baths and double closets, and another with a granite and granite bath overlooking the Sound. The principal suite is a showstopper, offering a Jacuzzi tub, vanity, water views, and a private great room with wet bar, which could also serve as an alternate primary bedroom with three-sided exposure and spiral staircase access to the rear yard. A third-floor walk-up attic provides an oversized closet, while the unfinished basement with exterior entrance is primed for completion — which already includes a full bathroom and wet bar. A separate one-bedroom duplex cottage includes an attached two-stall barn, with the option to convert the lower level back into a two-car garage — perfect for equestrian use or guest accommodations. The property’s five acres are lush, level, and gated, featuring a rear open meadow ideal for an in-ground pool, tennis court, or pickleball court. With ample space to expand and personalize, the estate offers unmatched potential to craft your dream home, fully tailored to your vision. With direct beach access, panoramic water views to Manhattan, and breathtaking sunsets, Sunset Beach blends timeless elegance with natural beauty in a way that few properties can.
