About This Property

At the foot of Flagstaff Mountain and just one block from Chautauqua Park, this is one of Boulder's most established and sought-after residential settings. Quiet, secure, and deeply rooted, the neighborhood offers something increasingly rare: true walkability paired with lasting prestige. Trails, parks, CU events, cultural institutions, neighborhood shopping, and downtown dining are all within easy reach-yet the home itself remains tucked away, calm, and private.Set on a generously sized, landscaped lot, the home is designed for how people actually live. The newly remodeled kitchen anchors the main level and opens seamlessly to an inviting family room-perfect for evening meals, relaxed entertaining, movie nights, and game-day gatherings. The flow is natural and intuitive, making the home feel immediately comfortable rather than formal.The lower level elevates the home's versatility, featuring a spacious recreation/media room and two private bedroom suites. Ideal for guests, extended family, or college kids home for the weekend, these suites live independently and offer flexibility rarely found in this location.Upstairs, en suite bedrooms include a serene primary retreat with treetop views and Flatiron glimpses. Outdoors, native stone patios in both the front and back yards create year-round living spaces-ideal for Colorado mornings, outdoor dinners, and fall afternoons with friends. Mature landscaping, a fenced yard for kids and pets, and thoughtful privacy complete the setting. Located within one of Boulder's most highly regarded school areas and less than an hour from DIA and Denver's professional sports and cultural scene, the home offers unmatched access without daily friction. This is Boulder at its most livable-where lifestyle, location, and long-term value align. Homes like this are not about trend or timing. They are about place. If you're ready to put down roots in one of Boulder's most enduring neighborhoods, this is your opportunity.

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.
