Property Description
Enjoy living the Colorado lifestyle in this beautiful remodeled 5-bedroom, 4-bath residence in Longmont's sought-after Quail Ridge neighborhood. Situated on a quiet, tree-lined street of well-maintained homes, this south-facing property includes a freshly repainted exterior, a new Class 4 impact-resistant 50-year roof, and a low-maintenance, sunlit front yard and covered porch. The main level unfolds into a light-filled great room featuring smart lighting, programmable electric shades, and a dramatic floor-to-ceiling stone linear gas fireplace with integrated media niche. The kitchen is a culinary enthusiast's dream, anchored by a marble-pattern quartz island and white cabinetry accented by industrial-inspired black hardware. High-end stainless steel Bosch appliances include a five-burner gas cooktop with downdraft, double ovens, and sleek refrigerator. Upstairs, two bright guest bedrooms with dual exposures share a spacious full bath. The primary suite is framed by triple south-facing windows and additional east/northeast light and a generous walk-in closet. A peaked ceiling enhances volume, while the five-piece bath offers dual sinks, soaking tub, separate shower, and water closet. The fully finished basement expands the home's versatility with a built-in media and library area, two additional bedrooms with large egress windows, a full bath, and a mechanical room with a recently serviced furnace and new water heater - ideal for guests, multigenerational living, remote work or hobbies. The extra-tall two-car garage is equipped with built-in cabinetry, abundant overhead storage and electric vehicle charging. Outdoor spaces include a covered back deck and side-yard patio framed by mature aspens. Enjoy proximity to downtown, with easy walk to the Longmont Recreation Center, Longmont Museum, town park and St. Vrain Greenway.
