Carved into the slope of Boulder's iconic Flatirons, this architectural residence represents a level of craftsmanship and execution whose true cost far exceeds what could be reproduced today, with replacement economics now well beyond $20,000,000. Homes of this scale and quality are no longer achievable in Boulder. Privately gated at the summit of Bellevue Drive, Boulder's most exclusive residential street, the home commands protected views across Chautauqua Park and the Flatirons. The setting is permanent and private. Spanning over 8,000 square feet, the residence was built without compromise. Flagstone echoing the Flatirons, hand-worked copper, Honduran mahogany, and walls of green sea glass reflect a level of material selection and execution rarely seen today. Architecture shaped by terrain and light, engineered for permanence rather than trend. The scale and quality are best understood in person. A separately sited guest residence under the same ownership may be incorporated by discussion, offering flexibility while allowing the primary residence to stand on its own. Direct access to Chautauqua Park, protected since the 1800s, ensures the surroundings remain untouched. Live privately. Create freely. Own what cannot be rebuilt.
