New price. Exceptional value. Incredible space. Welcome to 1429 Longhill Drive in Horizon Hill, now offered at $1,049,000. Set across from parkland and a neighborhood playground, this spacious colonial offers nearly 4,000 square feet on three finished levels in one of Rockville/Potomac’s most convenient locations. The home features 4 bedrooms, 2 full baths, 2 half baths, fresh neutral paint, hardwood floors, new carpet, generous natural light, and flexible living spaces designed for everyday comfort, working from home, and entertaining. The renovated French country kitchen includes custom cabinetry, granite countertops, stainless steel appliances, hardwood flooring, and a charming window seat. Its location next to the living room also creates excellent potential for a more open future kitchen/living layout. The bright sunroom overlooks the private rear setting, while the custom deck and covered front porch offer inviting outdoor spaces. Upstairs, the spacious primary suite includes hardwood flooring, a wood-burning fireplace, private office, and a beautifully renovated spa-like bath. The finished lower level adds a large recreation area, luxury vinyl plank flooring, half bath, storage, and workshop space. Additional highlights include double-pane windows, upgraded landscaping, a 2022 architectural roof, and 2021 furnace and A/C. Ideally located near Park Potomac, Cabin John Village, Rockville Town Center, Pike & Rose, parks, trails, shopping, dining, fitness, and major commuter routes including I-270, Falls Road, and Wootton Parkway. For buyers looking for space, updates, location, and a compelling price in 20854, this is one of the best values on the market.
