Perched atop the crest of one of Mapleton Hill's most desirable streets, 403 Mountain View has it all. Historic character, strong architecture and an unbeatable in-town setting give this home a presence that is immediately distinctive. Inside, original details are balanced by thoughtful updates, creating rooms that feel warm, collected and beautifully livable. A dramatic glass atrium brings exceptional light into the heart of the home and captures seasonal and mountain views, while generous living and dining spaces flow easily for both everyday life and entertaining. A private lower-level entrance creates an independent living arrangement with two bedrooms, a separate bath and generous living space, ideal for extended family, long-term guests, an au pair, or simply added privacy and flexibility. The primary suite is equally considered, with a beautifully appointed bath and steam shower, while three generous in-wall/eave storage areas on the upper level provide valuable additional storage.Outside, the home really comes into its own. Multiple porches and patios create places to gather, dine and unwind throughout the day, while the private pool and waterfall bring an effortless resort-like quality to the setting. An 8' x 10' garden/storage shed tucked behind the pool adds convenient additional storage. Seller has also secured City of Boulder Landmark Alteration Certificate approval for a proposed one-car garage and enclosed mudroom-an unusual and valuable opportunity in historic Mapleton Hill. Flatiron views, mature landscaping, an electric gate and 220V car charging station add both character and convenience. There is also one off-alley parking space at the rear of the property.And the location is next to impossible to beat: just moments from Pearl Street, downtown restaurants and shops, neighborhood cafes, Mt. Sanitas and some of Boulder's best trails. This is Mapleton Hill living in its most complete form-private, connected, architectural and distinctly Boulder.
Mapleton Hill, located between Broadway and 9th Street, is a historic and residential Boulder neighborhood with tree-lined streets and landmark Victorian-era architecture. The neighborhood’s character concentrates around the Mapleton Avenue and Broadway corner, where café patios and small storefronts meet the steady rhythm of campus-bound traffic. Community pillars include the Boulder Theater, the Boulder Museum of Contemporary Art, and the Boulder Public Library’s Main Branch. Brick sidewalks and deep front porches set a classic streetscape, while views toward the Flatirons frame many blocks. North Boulder Park and nearby trailheads shape an outdoors-forward routine without leaving town. Pearl Street’s pedestrian energy sits just downhill, balancing quiet blocks with a lively cultural calendar.
