Set on more than four private acres at the end of a quiet Bedford Hills cul-de-sac, this five-bedroom custom contemporary was reimagined by NYC architect David Howell in collaboration with local architect Robert Robinowitz. Clean lines, custom woodwork, clerestory windows, expansive glass and wide, light-filled hallways define the home, anchored by a dramatic staircase and an open, airy sense of scale. The main level centers on a large Scavolini kitchen and lounge area with a double-sided gas fireplace, along with a spacious living room with double-height ceilings, dining room, powder room and flexible office/playroom. Two additional bedrooms or offices share a full bath. Off the living room, a large deck steps down to a bluestone patio and fire pit, extending the living and entertaining spaces outdoors. Upstairs, the primary suite features radiant-heated floors, a 38-inch gas fireplace, Carrera marble shower, Blu Bathworks fixtures, Duravit tub and sleek custom closets. Two additional bedrooms, connected by a playful peek-a-boo opening, share a beautifully appointed bath with double vanities. A laundry room completes the second floor. The walk-out lower level provides substantial flexible space, a second kitchen and abundant storage. Outside, more than four acres encompass expansive lawns, mature plantings and irrigation, along with a Wagner pool with automatic cover and a generous poolside patio with an aluminum pergola and motorized louvers. A three-car garage with EV charging and a whole house generator complete this modern property. Exceptionally private yet minutes from Bedford Hills, Mt. Kisco, Bedford Village, Metro-North and major highways, this is a distinctive contemporary combining architectural pedigree, a highly livable layout and a glorious large, level backyard.
