Transforming ordinary properties into sustainable, innovative commercial developments.
We specialize in sustainable redevelopment—reimagining underutilized properties and transforming them into vibrant, purpose-driven spaces that enrich local communities. With a diverse portfolio spanning 650k feet of office, medical, industrial, warehouse, and retail properties, we proudly support more than 300 tenants, primarily throughout Longmont and Boulder, Colorado. Our commitment to exceptional service and long-term relationships has earned us industry-leading recognition for tenant retention and satisfaction. In addition to our commercial work, we selectively take on custom residential projects, bringing the same vision, integrity, and attention to detail to every home we create. Our historical mixed-use renovation in downtown Lafayette, CO won the Governor’s award for Adaptive Reuse.
