Description

Located on one of Newlands quietest streets a stone "Foursquare-style" home steeped in tradition and Landmarked as a historical 1903 residence, presents itself as a testament to Boulder's past. This same residence equally celebrates Boulder's future, which now heralds the 2026 cultural and economic impacts of the Sundance Film Festival. In 2011, the renovation of the original home and the addition of 2, 500 sq. Feet of new structures achieved the highest level of residential construction, earning a LEED Platinum Certification. It is one of 169 residential homes in all of Colorado to have ever earned this award. This distinctly creative property seamlessly blends timeless character with modern sustainability, showcasing a design that harmonizes architecture with nature. Residing on an expansive 12, 500-square-foot lot that features fruit trees, a park like sustainable lawn with remarkable boulders and sky views, this beautiful house awaits its next steward. This home is designed to promote wellness, featuring temperature-regulating structurally integrated panel construction, a 10 kW solar array, low-VOC finishes, and a south-facing passive solar orientation. The ranch-style layout features a lofted second bedroom, ideal for guests or a private office, while an 850-square-foot flexible studio with soaring ceilings inspires creativity and connects to a licensed, income-producing 1-bedroom/1-bath ADU. Four stone-crafted, raised organic garden beds and a sunlit indoor-outdoor flow create a truly magical retreat just moments from Ideal Market, North Boulder Park, and extensive mountain hiking trails. Pre-inspected and unlike any other home in Newlands, this residence is a truly one-of-a-kind fusion of history, innovation, and Boulder's natural beauty.
