In sleepy Bedford Corners, New York, 40 miles north of New York City, houses can command eight-digit prices. And they look it: in certain Bedford enclaves, rambling Tudors sit on lawns manicured into a perfection that could only be surpassed by AstroTurf. The Bedford Residence, designed by New York City-based Joel Sanders Architect (JSA) in collaboration with landscape architect Diana Balmori, breaks from convention. The clients, a professional couple with adult children, sought a low-key refuge from city life.

Inside, the living room, dining room, and kitchen unfurl in a series of unpartitioned spaces. Areas where the clients desired seclusion, such as the master-bedroom suite, are tucked away from the communal rooms, which are united by a wide stripe of poured-concrete flooring. Bluestone appears throughout the residence, in the living room as the fireplace wall, and outside in the front and rear as barriers and enclosures. A deck at the rear of the house leads down to the pool, enclosed on three sides by the ubiquitous bluestone. “Our idea was to connect inside and outside with a uniform material palette,” says Sanders.
