Single Family Home for sale in Boulder, CO

for $4,200,000 with 3 bedrooms and 3 full baths. This 3,258 square foot home was built in 1900 on a lot size of 0.29.

Centrally, located on one of Newlands' quietest streets is a distinctive turn of the century, stone-crafted home that is landmarked as a Boulder historical residence. Yet this classic home equally celebrates Boulder's future. The house sits on a 12,632-square-foot quadruple lot that features mature trees, large boulders, and expansive sky views. This home is designed to promote wellness, featuring structurally integrated panel construction that regulates temperature, a 10-kW solar array, low-VOC finishes, & a south-facing passive solar orientation. Completely renovated in 2011, the restoration of the original dwelling and the addition of 2,500 sq. ft. of new structures achieved the highest level of residential construction, earning the esteemed LEED Platinum Certification by the United States Green Building Council (USGBC). It is one of 169 residential homes in all of Colorado to have earned this award. The ranch-style layout includes a lofted second bedroom, ideal for guests or a private office, while an 864-square-foot flexible studio w/soaring ceilings inspires creativity and invites repurposing. It is currently configured as a fully operational professional photography studio with a built-in makeup station. Above on the 2nd floor is a light-filled, licensed, income-producing 1bed/1bath ADU w/unobstructed views of Sanitas Mountain. Four stone-crafted, raised organic garden beds & a sunlit indoor-outdoor flow create a truly magical balance of living space and nature. The home is within walking distance to North Boulder Park, the new Alpine-Balsam development, and Sanitas hiking trails. Pre-inspected and unlike any other home in Newlands, this residence is a fusion of history, innovation, and Boulder Open Space. This one-of-a-kind home honors both environmentalism and creativity. 2027 heralds the international debut of the Sundance Film Festival in Boulder. Please see Tim Goodacre's website to view the owner's video that conveys the transformation of this property.
