Welcome home to 7316 Walnut Knoll Drive, newly refreshed inside and out and tucked at the end of a quiet cul-de-sac in the non-HOA Walnut Knoll community of Springfield! This beautiful colonial offers approximately 3,358 total square feet across three finished levels. It sits on a lot that backs directly to Fairfax County parkland, giving you privacy and wooded views year-round. Hardwood floors run through the main living areas and lead to a cozy family room with a classic brick fireplace. Upstairs you will find 4 bedrooms & a nursery connected to the primary, easily converted back to 5th bedroom. The walk-out lower level features a brand-new ceiling with recessed lights, a full bath, and multiple flexible rooms, ideal for a rec room, home office, gym, or guest suite. Out back, step onto the expansive composite deck with a sturdy aluminum cover, overlooking multi-level hardscaping, stone steps, and lush parkland. It's the perfect spot for morning coffee or entertaining.
