Nestled on a picturesque and quiet tree-lined street in the heart of Watertown, this 1920s Colonial offers a rare combination of historic scale and essential modern upgrades. The home immediately impresses with an inviting foyer that leads into an oversized living room anchored by a classic wood-burning fireplace. While the kitchen is cozy and efficient, it is fully equipped with a brand-new refrigerator, a reverse osmosis water filtration system, and a new water softener. The adjacent formal dining room is bathed in natural light and easily accommodates a large table, making it the true hub for daily meals and conversation. What truly sets this property apart is its sheer versatility and the peace of mind provided by recent infrastructure investments. Since 2023, the owners have added a comprehensive security system, a new hot water heater, and a new washer and dryer. They also professionally waterproofed the basement for worry-free storage. With six to eight potential bedrooms spread across three finished levels, there is ample room for a home office, a quiet library, or a dedicated playroom. The massive third-floor retreat even includes its own full bath and a newly built, oversized walk-in closet. Outside, the fully fenced backyard and deck offer a private escape, complemented by a detached two-stall garage. Located just minutes from the hospital, local shopping, and Fort Drum, this home is a spacious and secure sanctuary designed to grow with you.
