An incredible opportunity to own a magnificently updated Colonial in St. James, offering striking finishes, versatile living spaces, and a midblock setting on a flat lot in a neighborhood with sidewalks and underground utilities within the Smithtown School District. Beautiful curb appeal begins with a newly expanded blacktop driveway with a cobblestone border, a brand-new roof, new cedar-impression siding across the front, and new vinyl siding around the home. A welcoming front portico with white columns creates an elegant entrance, while the private backyard and patio provide an inviting setting for outdoor dining and entertaining. Inside, freshly painted interiors, abundant natural light, and recessed lighting complement an open floor plan, with oversized marble flooring flowing through the formal living room, dining room, and eat-in kitchen. The brand-new kitchen makes a stunning statement with crisp white Shaker cabinetry, crown molding, matte black hardware, quartz countertops, and a gray-and-white marble-look mosaic backsplash. An efficient L-shaped layout provides generous cabinet and preparation space, while stainless steel appliances include a range, dishwasher, and refrigerator with water and ice. An undermount sink with a pull-down faucet sits beneath a window overlooking the backyard, and direct yard access makes indoor-outdoor entertaining effortless. The versatile first floor offers an additional room for use as a bedroom, den, or great room, along with a beautifully renovated full bathroom featuring floor-to-ceiling tile, recessed lighting, a white vanity, and a shower with sliding glass doors. A convenient mudroom includes brand-new LG front-loading laundry appliances and access to the garage. Upstairs, the primary bedroom features beautiful hardwood floors, recessed lighting, new two-panel doors, and direct access to a brand-new shared bathroom. Dramatically veined, large-format tile extends from floor to ceiling, creating a luxurious backdrop for a shower with sliding glass doors and its own window. A distinctive vanity with arched cabinet fronts, a crisp white countertop, an undermount sink, and polished chrome fixtures adds designer appeal, complemented by a framed mirror, a three-light glass vanity fixture, recessed lighting, and crown molding. Additional upstairs bedrooms offer spacious layouts and hardwood floors. A partially finished basement provides additional space with high ceilings, recessed lighting, and vinyl plank flooring. Major mechanical updates include an electric heat pump heating system, new central air conditioning, and a new hot water heater. Natural gas is available on the street, with piping already run into the house. From its refreshed exterior to its beautifully appointed kitchen and bathrooms, this move-in-ready Colonial delivers an exceptional combination of style, comfort, and thoughtful updates.
