for $3,999,000 with 5 bedrooms and 4 full baths, 1 half bath. This 5,043 square foot home was built in 1990 on a lot size of 0.26.
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.
