Set on approximately 2.5 acres in Old Field, 126 Old Field Road is a completely renovated residence offering approximately 6,500 square feet, 6 bedrooms, 6 full bathrooms and 1 half bathroom, with the space and layout of a true North Shore estate. A dramatic two-story entry introduces the home, opening to beautifully proportioned formal and informal living spaces with hardwood floors, detailed millwork and an abundance of natural light. The great room is one of the home’s standout spaces, with soaring ceilings, a fireplace and an impressive wall of windows and doors overlooking the property. The renovated kitchen offers generous cabinetry, stone countertops, stainless steel appliances, a large center island and a separate eat-in area, with an easy connection to the surrounding living spaces. A formal dining room and additional front sitting room provide distinct spaces for entertaining without losing the home’s open, comfortable flow. The main level also offers flexibility for a first-floor primary suite or private guest suite, giving the home added versatility for extended family, guests or anyone looking for convenient first-floor living. The primary suite is exceptionally spacious, with a vaulted ceiling, room for a private sitting area, multiple windows and a large fitted walk-in closet. Additional bedrooms are generously sized, while the renovated bathrooms continue the clean, updated feel found throughout the home. Comfort features include central air conditioning and radiant heated flooring where available. The fully finished lower level feels like an extension of the home rather than an afterthought, with approximately 10-foot ceilings, a full bathroom, substantial storage and enough open space to create a gym, theater, bar, game room, lounge or multiple recreational areas. Outside, the home sits well back on a broad, manicured lawn surrounded by mature trees and established landscaping, creating a private setting that feels removed while remaining convenient to Stony Brook, Setauket and the surrounding North Shore communities. An attached 3-car garage, expansive driveway and front and rear irrigation complete the property. A rare combination of acreage, scale, extensive renovation and flexible living space in one of Old Field’s most established residential settings.
