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!
