Welcome to 189 Cambon Avenue, a meticulously maintained 4-bedroom, 2.5-bath Colonial set on a beautifully landscaped property in the heart of Saint James. From the moment you arrive, mature plantings, manicured beds, and a custom paver walkway set the tone for a home that's been loved and cared for inside and out. Inside, a center-hall foyer opens to a formal living room and formal dining room, both rich with hardwood floors and abundant natural light. A separate den with a brick wood-burning fireplace offers the perfect cozy retreat, while the eat-in kitchen flows easily to a breakfast nook and updated half bath. Upstairs, the oversized primary suite features a walk-in closet and updated en-suite bath, joined by three additional generously sized bedrooms and a beautifully renovated full bath. Major systems and exterior updates are already done — roof, windows, and siding have all been replaced. A full basement offers flexible recreation and storage space. Outside, the fully fenced backyard is a private retreat with privacy hedges, raised garden beds, a shed, and a newer custom paver patio ideal for entertaining. Two-car side-entry garage and oversized driveway complete the package. All within the award-winning Smithtown school district and just minutes from Saint James village's shops, restaurants, Lake Avenue, Harbor Road, and the LIRR. A turnkey opportunity in one of the North Shore's most beloved hamlets.
