The Flatirons shape Boulder's identity. Flagstaff defines the view. Set just beneath Flagstaff Mountain on some of the city's most prized ground, this is a home rooted in both nature and prestige. The location is unmatched. In a region ranked among the most desirable places to live in Colorado, and arguably the country, this small enclave consistently leads the way in demand, stability, and lifestyle appeal. Designed by Scott Coburn, the architecture reflects a timeless sensibility with clean lines, exceptional light, and a seamless connection to the outdoors. This is a home where proportion matters more than flash, and where well-considered spaces flow with ease. The result is a layout that invites calm, comfort, and quiet. Flagstone paths, terraced gardens, and multiple stone patios extend the living experience into the landscape. The lawn is framed by flowering crabapple trees, Japanese maples, and curated plantings, all enclosed by custom wrought-iron fencing. Morning coffee, late summer dinners, and crisp fall afternoons all find their rhythm here. Inside, the remodeled kitchen and gathering areas are fluid and welcoming, anchored by a built-in breakfast nook with cushioned wraparound seating. Upstairs, the primary suite opens to a private balcony with Flatiron glimpses in the shadow of Flagstaff. The lower level includes a media room, two additional bedrooms, a flexible space for fitness, office, or studio use, and a cool-storage room perfect for a wine collection. With solar power, mature landscaping, and strong structural integrity, the home is ready for thoughtful updates and poised to reward them. In a market where location is everything, this property offers one of the rarest advantages-enduring value in one of Colorado's most sought-after places to live. Just minutes from downtown, within Boulder's top-rated school district, and steps from miles of iconic trails, the setting speaks for itself.
