About This Home
Welcome to this truly one-of-a-kind North Boulder retreat, where modern comfort meets mountain serenity. Tucked in the foothills on a fully fenced lot, this single-level gem is just one block from Wonderland Lake, Foothills Park, and trails—with Broadway and public transit two blocks away. This home provides a peaceful, picturesque location while still just minutes from Pearl Street Mall. Inside, you’ll discover a thoughtfully renovated open-concept layout bathed in natural light, with warm wood floors throughout and radiant solar-heated hot water floors powered by a custom-built system and massive solar-heated water storage beneath the home. The heart of the home is the beautifully redesigned kitchen, complete with custom cabinetry, sleek countertops, stainless appliances, and a steel beam installation that allowed for expanded space and modern flow. The windows and doors perfectly frame the surrounding foothill views from nearly every room—including year-round views of Green Mountain from the primary bedroom. All three bedrooms and two three-quarter baths are located on the main floor, offering effortless single-level living. The home’s excellent solar gain keeps it bright and cozy in the winter, and with owned solar panels and a battery backup providing off-grid capability, this home is as sustainable as it is stylish. Outdoor living is exceptional, with three spacious patios—two of which feature sliding pergolas for shade—ideal for entertaining or peaceful relaxation under the Colorado sky. The studio includes a 1080p projector and motorized screen. A built-in outdoor TV adds even more functionality to your al fresco gatherings. The lush garden has been lovingly cultivated over several generations and features rich, thriving soil. Exterior trim and soffits were freshly painted in 2023. This is more than just a home—it’s a peaceful sanctuary that blends thoughtful design, sustainable living, and unbeatable North Boulder location.
