Building Geosolar in Colorado
Cornerstone Contracting has been the builder on the GEOS development in Arvada since the project’s inception. GEOS is the first sustainable, integrated community in Colorado where energy from the earth and sun replace all fossil fuels. We use a range of architectural materials—including brick, stone, and stucco—to create a variety of single-family homes, townhomes, live-work spaces, condos, and co-housing communities. Our involvement with GEOS reflects our commitment to creating sustainable communities that use zero energy to benefit our humankind and our planet.
