A Rare Boulder Estate Where Possibility Meets the Colorado Lifestyle! Set within a private enclave of just 17 homes on generous lots, this beautifully updated, gated estate on 4 acres offers a rare combination of space, versatility, and connection to Colorado's outdoors. Backing to hundreds of acres of open space and an extensive trail network, including equestrian routes, it invites an outdoor lifestyle just minutes from the heart of Boulder. Whether you envision equestrian living, a hobby farm, a car enthusiast's retreat, or simply a private estate with room to breathe, the possibilities are exceptional. Mountain views grace many rooms, while the dramatic great room showcases a soaring ceiling, moss rock fireplace, and a wall of west-facing windows framing the Flatirons. The kitchen features a Sub-Zero refrigerator, six-burner Dacor gas range, dual pantries, and Taj Mahal quartzite countertops. The spacious primary suite offers vaulted ceilings, a walk-in closet, and private balcony, while the en-suite bath features an oversized shower and separate soaking tub, a relaxing retreat to start and end your day. Multiple pasture areas- allowing up to 3 head of livestock, raised garden beds, a heated two-stall barn with matted floors and automatic waterers, and a riding arena with a sand-and-rubber base offer outstanding versatility.

The finished lower level offers flexible space for guests, extended family, an au pair, or recreation, while a generous loft provides the opportunity for a second home office. A newer roof, windows, and HVAC systems, plus owned solar panels, add comfort and energy efficiency. Pre-inspected and offered with a home warranty, this distinctive property combines thoughtful updates, exceptional flexibility, and an enviable Boulder-area setting.
