About This Home

As of March 2026

Commanding 80 acres of prime Boulder County land, this extraordinary estate offers sweeping, unobstructed views of the Front Range and Rocky Mountains from every corner of the property. At the heart of it all is a fully remodeled custom home, thoughtfully reimagined inside and out between 2015 and 2018 to elevate both comfort and style. Nearly 300 side-dump truckloads of soil were expertly moved from the lake in 2015 to shape the dramatic landscape berms that now frame the home-creating a sense of privacy while enhancing the stunning visual backdrop. That same year, a sprawling covered deck was constructed to extend the living space outdoors. Designed for year-round enjoyment, it features a motorized awning for effortless transitions between sun, shade-making it the perfect setting to relax or entertain against a Rocky Mountain backdrop. Inside, the gourmet kitchen was completely renovated with custom cherry cabinetry and rich leathered granite countertops, blending elegance with functionality. The primary bathroom was also fully reimagined, and the home's interior was transformed with reconfigured walls, new flooring throughout, designer lighting, and custom window treatments. The lower level is a versatile space ideal for multi-generational living or extended guest stays. It includes a full kitchen, a walk-in pantry, walk-in closet, new washer and dryer, a spacious open floor plan, and a luxurious bathroom featuring a Jacuzzi tub. Designed with both comfort and utility in mind, the property includes a fully climate-controlled, eight-run dog kennel with private outdoor access-ideal for breeders, trainers, boarding professionals, or your own favorite furry best friend. Water rights include 18 shares of New Ish, plus two domestic water taps. Farm equipment is included and features a Kabota tractor, a Honda Pioneer 700 UTV, and a riding lawnmower-ensuring you're well-equipped to care for the land.
