for $9,950,000 with 5 bedrooms and 6 full baths, 1 half bath. This 8,427 square foot home was built in 2004 on a lot size of 1.24.
A One-of-One estate carved into the slope of Boulder's iconic Flatirons, offered today at less than half its reproduction cost. Gated, private, and architecturally unmatched, this residence stands at the very peak of Bellevue Drive, Boulder's most exclusive street, where views sweep across Chautauqua Park and the timeless rock faces of the Flatirons. Built with materials sourced and crafted for permanence, flagstone mirroring the Flatirons, hand-carved copper, Honduran mahogany, and walls of green sea glass, this is a home where artistry meets engineering. What sets Bellevue apart is its rarity: one of the few private estates along Colorado's Front Range to offer not just a primary residence but a separate, equally compelling guest home, both integrated seamlessly into the terrain. Behind its gates, the property functions as a true private retreat, with two distinct dwellings shaped by nature and connected to the very fabric of Boulder. With direct access to Chautauqua Park, one of the most storied park lands in the West, protected since the 1800s, your backyard is guaranteed to remain untouched. Beyond architecture and setting, Bellevue is a property that cultivates lifestyle. Mornings begin with private access into Chautauqua. Evenings conclude with recovery in the spa and locker room. Every element serves a purpose. Fitness, wellness, retreat, creation, woven together in a residence that offers both inspiration and privacy. This is not only a home; it is the framework for the life Boulder promises at its highest level. Shaped by terrain, not trends, this is a place where screenplays are written, canvases fill with light, and books begin. Every angle was designed to inspire, while offering a level of privacy rarely found in Boulder or anywhere. Live privately. Create freely. Own the irreplaceable. This is two residences being sold together. 375 Bellevue an ADU/ Carriage House a 1 bedroom, 2 bathrooms, 1 car, 1,373 sq ft of living space, a $1.5 Million value.
