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 two-story glass atrium brings exceptional light into the center 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 a beautifully independent living arrangement, complete with its own en suite bedroom and generous living space, ideal for extended family, long-term guests, an au pair, or simply added privacy and flexibility. 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 make everything feel especially easy and luxurious. Flatiron views, mature landscaping and a dedicated wine cellar all add to the experience and the home's historic character. 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 iconic Mapleton Hill living in its most complete form-private, connected, architectural and distinctly Boulder. LIVE BOLDER, LOVE 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.
