Nestled at the base of Boulder’s iconic Flatirons, 770 Circle Drive occupies one of the city’s most extraordinary residential settings. Behind private gates, this exceptionally secluded 1.29-acre estate commands spectacular 360-degree vistas spanning the Flatirons, Chautauqua, downtown Boulder, Folsom Field and the Boulder Valley beyond. Step outside to one of the world’s most celebrated trail systems, where hundreds of miles of protected open space invite hiking, trail running and year-round adventure just moments from your front door, while Pearl Street’s acclaimed restaurants, boutiques and cultural attractions remain an easy walk away. Few properties anywhere offer such a remarkable balance of privacy, natural beauty and urban accessibility.

Spanning 8,066 finished square feet, the residence was thoughtfully designed to embrace its breathtaking surroundings. Soaring ceilings and dramatic walls of glass flood the interiors with natural light while framing unforgettable views from nearly every room. The expansive living room, elegant dining room, generous kitchen and inviting family room flow seamlessly together before opening to multiple terraces and outdoor living spaces, creating an exceptional setting for both intimate gatherings and grand-scale entertaining.

The primary suite is a private retreat defined by a dramatic curved wall of glass, fireplace, sitting area, spa-inspired bath and panoramic mountain vistas. Above, an expansive rooftop terrace provides one of the home’s most spectacular vantage points, where the Flatirons, Chautauqua, downtown Boulder and the surrounding valley unfold in every direction.

A fully equipped private apartment with its own kitchen, living area, bedroom and bath offers outstanding flexibility for multigenerational living, extended family, long-term guests, an au pair, caregiver or executive home office. Originally built in 1941 and thoughtfully expanded over time, the residence blends timeless architectural character with generous scale and the opportunity to enjoy it exactly as it is or thoughtfully personalize it for years to come. 770 Circle Drive represents one of Boulder’s rarest opportunities to own an estate where exceptional privacy, iconic scenery, world-class outdoor recreation and walkable urban living converge in a single, irreplaceable setting.
