About This Property

Nestled in the heart of Boulder's iconic Mapleton Hill, 424 Concord Way blends historic charm with modern comfort. Tucked at the end of a quiet dead-end street, the home offers privacy, sweeping Mt. Sanitas views, and easy access to downtown Boulder's shops, restaurants, and trails. Enjoy morning coffee on the covered front porch, then stroll along tree-lined streets lined with classic turn-of-the-century homes.Inside, historic character meets contemporary style. Restored woodwork and molding frame light-filled rooms with 9-foot ceilings and hardwood floors throughout. The kitchen features cherry cabinetry, Silestone countertops, high-end appliances, and a layout flowing into bright living and dining areas. Both bathrooms boast modern sinks and designer tile. Behind the scenes, the home is thoughtfully updated: spray foam insulation in the foundation and roof, vapor barrier in the crawl space, high-efficiency gas furnace, updated ductwork, electrical, plumbing, USB outlets, tankless water heater, and a repointed foundation.Outdoors, the fully enclosed yard frames one of the neighborhood's loveliest gardens, with raised vegetable beds, flagstone patios, and winding paths. Front and rear porches invite relaxation from sunrise to sunset. A detached one-car garage with alley access and off-street parking is paired with a flexible outbuilding, perfect for a studio, home office, or creative space. Every detail reflects a commitment to character and livability, resulting in a move-in ready Mapleton Hill gem that beautifully captures the best of Boulder living.
