A rare and remarkable offering in unincorporated Boulder County, this extraordinary earth-shelter residence commands 27 striking acres abutting 1,700 acres of protected federal land on the east side of Table Mountain. Unobstructed views stretch across the Flatirons, foothills, eastern plains and city lights beyond – a living panorama that shifts with every passing storm and season. Built by Terra-Dome with a concrete structural system and integrated into the hillside beneath a grass-covered roof, the home embraces passive solar principles, with its south-facing orientation and natural insulation helping maintain relatively stable indoor temperatures throughout the seasons. Inside, beautiful arches and wood-beamed ceilings lend an organic warmth, while an updated kitchen with quartz and butcher block countertops, tile, oak and maple flooring, a primary bedroom with library and secondary bedrooms with window seats and lofts create a uniquely soulful living environment. Deer, elk and birds of prey are frequent visitors. Agriculturally zoned with horses allowed, this exceptional property offers remarkable flexibility approximately 15 minutes from Boulder, Longmont and Niwot. Offered as-is, the residence presents an opportunity to renovate, reimagine or explore the potential to rebuild up to 5,578 square feet, allowing the next owner to create a home tailored to their vision.
