About This Property

A Rare Opportunity Where History Meets Modern Living.

Built in 1750 and thoughtfully renovated in 2005. White clapboard, black shutters, cedar shake roof, and copper gutters set a timeless exterior, framed by professionally designed grounds.

A wide entry hall opens to living and dining rooms bookended by floor-to-ceiling stone fireplaces. Hardwood floors and detailed millwork mark the quality craftsmanship throughout every room.

The main house offers four bedrooms and three and a half baths. The gourmet kitchen anchors daily life. Sub-Zero and Viking appliances, generous custom cabinetry, and a large center island flows into a family room that opens directly onto the patio and gardens.

The primary suite is a retreat in its own right: vaulted ceilings, a stone fireplace, walk-in closet, and a spa-inspired bath with soaking tub and glass-enclosed shower.

A separate carriage house extends the home's character and livability. The main level offers a welcoming sitting room, while upstairs an open living area with kitchenette is bathed in natural light. Equally suited to hosting guests or serving as a private studio or work-from-home retreat. Outside, grounds designed by acclaimed landscape architect Jan Johnsen unfold around an oversized stone patio with outdoor kitchen, generous space for hosting friends, or enjoying the surrounding beauty in complete privacy. A vegetable garden and expansive lawn extend the property further, all bordered by protected land that offers a balance of openness and seclusion that can't be replicated.

A heated three-car garage rounds out the property. Byram Hills School District. Chappaqua train parking eligibility.
