This exceptional luxury residence blends mountain elegance with refined design, just two blocks from scenic trails at the base of the foothills. Set on nearly an acre, the lush, secluded, landscaped grounds, complete with Silver Lake Ditch water rights, feature mature trees, gardens, multiple patios, and a private pool - currently unfilled in support of local water conservation efforts, but is designed and ready for future enjoyment, creating a serene, Aspen-inspired retreat in one of Boulder's most coveted neighborhoods. The backyard is further enhanced by an elaborate custom playground complete with a clubhouse, climbing wall, slide, swings, and gym rings, offering an exceptional outdoor experience. Inside, 20-foot vaulted ceilings and floor-to-ceiling windows fill the living spaces with light, complemented by six fireplaces throughout. The home offers two primary suites with spa-like baths, including a steam shower, soaking tub, and expansive walk-in closet, along with multiple ensuite bedrooms. An extraordinary walk-in pantry with abundant open shelving, along with additional closet storage and built-in shelving throughout, elevates both functionality and organization. A main-level office, upstairs study, and library with fireplace provide ideal work and relaxation spaces, while flexible areas include a playroom, rec room, and private studio apartment featuring the added convenience of a small refrigerator. Skylights, striking architectural details, and ideally situated decks with breathtaking Flatirons views are complemented by the added convenience of a dedicated kitchen generator, completing this truly exceptional property.
