Located on a quiet street in Polo Fields and within walking distance of the Herndon Metro, 12809 Tournament Drive offers thoughtfully updated living space, a large flat fenced yard, and a location that keeps Dulles Airport, Reston Town Center, Old Town Herndon, the Dulles Toll Road, and Fairfax County Parkway all close at hand. A brick front exterior, manicured landscaping, two-car garage, and two-story foyer create a welcoming first impression. Hardwood flooring extends through the foyer, hallways, formal dining room, and kitchen, while 9-foot ceilings add to the sense of space throughout the main level. The remodeled kitchen features 42-inch white cabinetry, premium granite countertops, a generous center island, stainless steel appliances, tile backsplash, recessed lighting, and a large breakfast area surrounded by windows that bring in exceptional natural light. The kitchen flows directly into the family room and opens through a sliding glass door to an oversized deck with multiple seating areas overlooking mature trees, open space, and a beautifully maintained rear yard. Upstairs, the spacious primary suite includes a walk-in closet with a custom Elfa organization system and a newly renovated bath featuring a white dual-sink vanity with abundant storage, quartz countertops, a freestanding soaking tub, seamless glass no-curb shower, contemporary tile selections, and a private water closet. Three additional generously sized bedrooms share an updated bath with Carrara tile, quartz-topped vanity, and barn-door style glass shower enclosure, while two of the bedrooms also include walk-in closets. The fully finished walk-up lower level provides remarkable flexibility with a county-permitted full kitchen featuring 42-inch cabinetry, premium granite countertops, stainless steel appliances, tile backsplash, and a separate buffet and bar area with granite surfaces and built-in beverage cooler. Additional lower-level spaces include a large recreation room, exercise room with water hookup, private den or office with French glass doors and recessed lighting, and an oversized laundry room with white shaker cabinetry, granite countertops, abundant storage, and space for hobbies, crafts, or household organization. Recessed lighting throughout the lower level, tile flooring, a walk-up exit to the backyard, and the combination of privacy, open space, and extensive indoor living areas make this home equally suited for everyday living, entertaining, multigenerational needs, or extended guest stays.
