PRIVATE RETREAT IN NORTH ARLINGTON! Tucked away on a quiet cul-de-sac and set on a rare 1.23-acre wooded lot in sought-after North Arlington, this modern rambler presents an exceptional opportunity. Offering over 5,400 square feet, custom built in 1987, the home offers 2 bedrooms and 3 full baths with timeless character and tremendous potential to renovate, expand, or build new in a premier location. Designed with one-level living options, the main level features 2 bedrooms and 2 full baths, along with spacious living and dining areas, souring ceilings and expansive windows that fill the home with natural light. A stunning double-sided stone fireplace anchors the central living spaces, adding warmth and architectural interest. The eat-in kitchen, formal dining room, and rear deck overlook lush, tree-filled views ideal for entertaining or enjoying the peaceful, private setting. The lower level features a 3rd bedroom and full bath with flexibility for additional bedrooms, baths, a recreation room, home theater, gym, office space, storage area and more. While the kitchen and baths are ready for updating, the home's solid construction and incredible lot size offer endless possibilities. Surrounded by substantial homes, some neighbors have expanded upward, while others may consider new construction (subject to County approval and resource protection area considerations). Opportunities like this are rare in such an established and highly desirable neighborhood. Enjoy nearby parkland along the Potomac River and C&O Canal, neighborhood camaraderie on adjoining cul-de-sacs, and inclusion in the Donaldson Run Recreation Association pool boundary. Zoned for Jamestown Elementary, Williamsburg Middle, and Yorktown High School. Ideally located just minutes to Chain Bridge and the GW Parkway for easy access to Washington, D.C., and Tysons. Bring your vision and restore or reimagine 3633 N Nelson Street into something truly special.
