About This Property

Set along coveted Dune Road, this jetty-protected oceanfront property spans approximately 0.95 acres with 100 feet of frontage on Dune Road. The shingled Post-Modern residence offers approximately 3,000 square feet of interior living space, which includes an attached 250-square-foot garage, and has been thoughtfully renovated to blend contemporary design with the relaxed elegance of Hamptons living.

Recent upgrades include a new cedar roof, expansive mahogany decking with custom stainless-steel railings, solid custom-crafted wood doors throughout, and imported designer hardware. Expansive windows and dramatic floor-to-ceiling glass doors fill the open-concept living and dining areas with natural light, creating a seamless connection to the oceanfront setting. Fully customized wall-to-wall glass doors anchor the main living space, while oversized Andersen sliding doors enhance the first-floor bedroom and den, allowing for effortless indoor-outdoor living. A fireplace adds warmth and character, while the refined modern kitchen is thoughtfully designed for everyday living and entertaining.

The first-floor den provides a comfortable retreat with direct access to the deck and pool. Beautifully appointed bedrooms capture sweeping water views, including two spacious ocean-facing suites, each with its own private balcony overlooking the Atlantic.

Outdoors, a heated gunite pool is surrounded by expansive mahogany decking, creating an exceptional setting for relaxation and entertaining. A private boardwalk leads directly to the ocean beach, while a rare, deeded right-of-way to the bay offers the opportunity to enjoy both the Atlantic Ocean and the bay from this exceptional Dune Road property, delivering the quintessential Hamptons coastal lifestyle from sunrise to sunset.
