543 Scarborough RoadBriarcliff Manor, NY 10510Price: $1,795,000

A rare Mid-Century Modern by noted Westchester architect Roy Sigvard Johnson, whose work reflects Frank Lloyd Wright's organic design principles, 543 Scarborough Road is bordered by protected conservation land adjoining the Old Croton Aqueduct State Historic Park. Featured in House & Garden Building Guide and HisTOURy's 2025 architectural tour series, the home's sculptural rooflines, dramatic geometry and walls of glass draw the wooded landscape into the interiors from the moment you enter. A welcoming entry leads to the dramatic step-down living room, where a substantial brick fireplace and floor-to-ceiling glass overlook the stone terrace and surrounding landscape. The adjacent dining room opens directly to the patio for effortless indoor-outdoor entertaining, while the eat-in chef's kitchen pairs warm wood cabinetry and clerestory windows with Wolf and Miele appliances. The first floor also offers a flexible bedroom or office with a full bath, mudroom and laundry room, plus direct access to the two-car, EV-ready garage and whole-home backup generator. Upstairs, the primary suite offers a spa bath and two custom walk-in closets, while additional bedrooms feature angular ceilings and treetop views. The lower level adds more than 900 square feet of bonus space for fitness, recreation and flexible use. Outside, expansive patios and outdoor living areas, a custom heated hot tub set into natural stone, and a seasonal waterfall with a dedicated viewing deck and stairs descending to the stream create a private retreat, while a trail connects directly to the Old Croton Aqueduct for walking and cycling. Scarborough Metro-North is just 1 mile away, with express service to Grand Central in approximately 46 minutes. Architecture, provenance and landscape converge here in a home designed to live in harmony with its surroundings.
