About This Home

250 Oyster Bay Road

Exceptional brick estate offering 9,023 sq ft of refined living with 6bedrooms and 5.5baths on nearly two private acres in Locust Valley. Built in 2009, the home showcases custom mahogany millwork throughout, a dramatic two-story foyer with a sweeping butterfly staircase, and a great room framed by a soaring wall of arched windows. A first-floor library and dedicated meditation room offer quiet retreats. The chef's kitchen features rich custom cabinetry, coffered ceilings, an oversized center island, and a full suite of Viking appliances including a professional gas range, complemented by a butler's pantry with built-in wine storage and dual Viking wine refrigerators. The grand-scale primary suite is a wing unto itself, with a fireplace, sitting area, boutique-style dressing room, and an oversized spa bath with soaking tub and separate shower. A full-width entertainer's terrace spans the rear of the home, overlooking the manicured grounds. Below, the expansive walk-out garden level opens to the lawn through a graceful arched loggia — ideal for recreation, gym, or guest space. A rare blend of scale, craftsmanship, and privacy moments from Locust Valley village.
