AN INTRODUCTION
A closer look.
Commanding water views, exceptional privacy, and more than three acres define this Centerport estate overlooking the harbor and Long Island Sound. Designed in an English Country style, the nearly 8,000 square feet of usable living space unfolds with a sense of scale, from the double-height foyer and 12-foot tray ceilings to multiple fireplaces and expansive rooms oriented toward the water. A richly detailed library creates a more intimate retreat, while the kitchen, generous bedroom suites, and private guest or in-law accommodations support both everyday living and extended stays. Outdoors, the setting becomes the focal point, with a heated in-ground pool and integrated spa, expansive Trex decking, and elevated views across the surrounding landscape. A natural path leads toward the shoreline, adding another connection to the property’s coastal setting. A high-ceiling walk-out lower level, three-car garage with bonus space above, multi-zone HVAC, whole-house generator, and recent gas line complete the offering. Set within the Harborfields School District and convenient to Centerport Harbor, Huntington Village, and Northport Village, this is a substantial North Shore estate shaped by privacy, architecture, and water.
