Description
Some homes offer a view. 855 Circle Drive offers an escape - with the Flatirons and foothills as your backdrop. Tucked into a private hillside just below Flagstaff Mountain, 855 Circle Dr sits in a world of its own, sheltered by mature trees, wrapped in stillness, yet moments from the heart of Boulder. The Flatirons rise directly in front of you. Trailheads begin nearby. And the sounds of the city simply don't reach you here. This is the setting that renowned Boulder architect Charles Haertling chose for his own personal residence - and that provenance speaks for itself. The home's clean modern exterior gives way to an interior of remarkable warmth, with tongue-and-groove ceilings, exposed beams, hardwood floors, custom woodwork, and skylights that flood the space with natural light throughout the day. Every window is a frame for the landscape beyond. On the upper level, an open-concept living, dining, and kitchen layout flows toward large sliding glass doors that open onto a south-facing terrace oriented directly at the Flatirons. The primary suite offers Flatiron views, patio access, a five-piece bath, and walk-in closet. A dedicated office and a deck off the kitchen overlooking the city complete the level. The outdoor spaces are exceptional: stone patios, terraced gardens, and meandering mature landscaping including cherry and apple trees that bloom in spring, offer shade in summer, and glow in autumn. The grounds feel like a private nature preserve, designed for quiet mornings & golden-hour evenings. Whether you're entertaining on the terrace, setting out on a trail at dawn, or simply embracing the stillness, the outdoor life here is extraordinary. 855 Circle Drive requires nothing of you except to arrive and settle in. With 3,791 sqft across two well-conceived levels, including a spacious family room, three additional bedrooms, a guest suite, and flexible work-from-home spaces, the home functions beautifully for everyday living and generous hosting alike.

10/10GreatSchools RatingParent Rating AverageTerrible experience here. Constantly made fun of and picked on by students and teachers treated me like a total idiot. Went from being respected by peers and teachers at my old school to ridiculed and laughed at by the entire class.Other Review2mo ago - Manhattan Middle School Of The Arts And Academics

5/10GreatSchools RatingParent Rating AverageThis is our first year at Manhattan and we are incredibly pleased with the middle school experience our son is having. When we first moved to the neighborhood (when the school was under old leadership) we were warned to look elsewhere because of some institutional issues. By the time enrollment came around last year, the new principal had infused the school with incredible energy and he was adamant it was his top choice. It feels like a vibrant place where the whole community is striving to improve and make it the best three years possible for every kid there. The principal shared that test scores showed 22% growth last year, which is pretty mind-blowing! I'm always a fan of a place that is focused on growth and improvement rather than one that's resting on its reputation and we've definitely found that at Manhattan.Parent Review6mo ago - Flatirons Elementary School

6/10GreatSchools RatingParent Rating AverageWe love Flatirons! They offer excellent programs for kids of all abilities, and I’ve been especially impressed by the diversity of what they provide, such as guest speakers, STEAM programs, community involvement, and extracurricular opportunities. The teachers are incredibly supportive and genuinely care about the wellbeing and growth of their students.Because it’s a smaller school, students receive much more individualized attention, which has made a big difference for our family.Parent Review4mo ago
