About this House

Exquisite Oceanfront Masterpiece! Indulge in the epitome of waterfront opulence at this sprawling Mediterranean estate on the legendary Dune Road, where 174' of ocean frontage and uninterrupted Atlantic vistas unfold across a meticulously manicured 1.74 acre sanctuary. Crafted as a private Hamptons haven, this 4,618 square-foot, 5 bedroom, 6 bath architectural gem bathes in natural luminescence, its open and expansive, light-drenched interiors evoking the serenity of a world-class resort while delivering the intimacy of a bespoke legacy. Filled with possibilities on Exterior color choices as in artist rendering in first photo, this house could be the one of your dreams as is now, or re-designed.

Step into a symphony of seamless sophistication with an open-concept floor plan that redefines coastal grandeur. The heart of the home is a culinary atelier worthy of Michelin acclaim—a chef’s kitchen adorned with state-of-the-art Sub-Zero, and Viking, appliances, cascading granite countertops, and custom cabinetry that marries form and function in effortless elegance. Flowing adjacently are dual palatial living spaces: a grand salon for intimate gatherings and an oversized great room crowned by a majestic stone fireplace, where flickering flames dance against panoramic ocean horizons.

Ascend to the second level, where dual primary suites await as private sanctuaries of unparalleled luxury. Each features spa-like marble ensuites with soaking tubs, rain showers, and heated floors, ensuring rejuvenation at every turn. A fireside den/library serves as a refined retreat for contemplation or conversation, while three additional guest suites—each with its own en-suite sanctuary—offer sumptuous privacy.

Outdoors, the estate transcends mere grounds to become an al fresco Eden. Enveloping the heated Gunite pool and bubbling spa is a vast expanse of premium mahogany decking, evoking the decks of a superyacht under the Hamptons sun. Lush, landscaped terraces, whispering sea breezes, and a discreet, meandering boardwalk lead directly to your private ribbon of dune-backed beach, where the rhythm of the waves becomes your daily symphony. Two garages and a very wide pebbled driveway large brought to fit 10 vehicles!

This is more than a residence—it’s a legacy of lavish living, a RARE FIND and where every detail whispers exclusivity and every sunset heralds renewal. Secure your slice of eternal summer; inquiries invited for this irreplaceable Dune Road icon. One of the most incredible views exists here as opposite the home on Bayside, exists barren bayfront land, making this home and lot, the only one of its kind left!
