Step into a rare piece of New Jersey history at 704 Greenbrook Rd. Believed to be North Plainfield's oldest home, with origins dating to circa 1740, this extraordinary residence is thought to have once served as a carriage house. Enjoy the charm of a historic home without the restrictions typically associated with historic designation. Thoughtfully updated while preserving its original character, the home features refinished hardwood floors, original wide-plank floors upstairs, a walnut staircase, original fireplaces (as-is), an updated kitchen, first-floor laundry, and a beautifully renovated bath with slate, tumbled marble, and natural stone. Classic steam heat adds cozy comfort throughout. Outside, enjoy a private yard with a new swimming pool, raised garden beds, workshop garage, and a gated driveway with parking for approximately 10 vehicles. Recent improvements include foundation enhancements and a newer furnace. The property is also outside a FEMA-designated flood zone. Conveniently located just minutes from the Dunellen NJ Transit station, major highways, shopping, and dining. A truly one-of-a-kind home where nearly three centuries of history meet thoughtful modern updates, offering exceptional craftsmanship, timeless character, and an unforgettable story.
