About Us

Industry Leading General Contractors in Boulder, CO
Constructive Alternatives was first established in the 1990s to redirect our hotel and high-rise experience towards high performance, earth-sheltered, net zero, and off-grid luxury homes, ranches, recording studios, monasteries, and sanctuaries. It’s been our life’s work honing our construction trades skills and renewable systems practices while creating some phenomenal commercial and residential structures. We bring an ICC Class A (Building Unlimited) General Contractor license and decades of experience completing more award-winning, eclectic, green-built homes and ranches than we can count. Our clients and partners have also been able to leverage our past experience leading huge crews as the superintendent for iconic buildings such as downtown Denver's 30-story Tabor Center, Denver Tech Center's 10-story Empower Retirement Triple Towers; picturesque Vail Marriott Mountain Resort; and the highly energy-efficient Boulder County Justice Center and Boulder County Jail. All told, we've built, remodeled, or "renewably" energized hundreds of homes, commercial properties, executive hangars, earth-sheltered dwellings, sound studios, and luxury housing developments. Our sweet spot today is combining high performance building envelopes with renewable energy, HRV/ERV, battery storage, smart home, and reclaimed water systems. We love erecting high R-value, super strong structures that use recycled or sustainably-sourced building products like insulated concrete forms and cross-laminated timber; installing geothermal and solar thermal hydronic heating & cooling systems; interconnecting HRV/ERV air handlers for healthy indoor environments' and designing/installing renewable power systems (solar PV, wind, and micro-hydro) with battery back-up for "off-grid" homes, pools, ranches, and remote commercial projects. When we have the opportunity to work with others who want to BUILD BETTER TOGETHER, that's where the magic happens!
