The Alliance Center’s building is a historic gem in the heart of lower downtown Denver. Below is a brief history of its journey.


Our building was first named the Kennicott-Patterson Transfer and Storage building. It was erected in 1908 and originally used as a warehouse. To honor the beautiful twentieth century architecture, we have maintained and highlighted many aspects of the original structure, including the large wooden support beams and the original brick. Externally, the building’s original loading docks and rail spurs are still visible.


In 2004, our founder, John Powers, purchased the building, and The Alliance Center was born. The goals were to create an educational outreach center promoting sustainability and to model innovative green building practices via the reimagining of historic structures. The building underwent major energy efficiency and systems renovations in 2004 to provide a sustainable, collaborative working and meeting space for the community.


In 2014, our building completed its most recent transformation as part of a thirteen million dollar renovation project. We replaced all of the interior components, systems and structures, excluding wooden support beams, exterior brick facades, and windows. Our beautiful space now showcases these modern technologies and historical furnishings. The Alliance Center has grown to become an award-winning facility and a leader in sustainable design. To date, The Alliance Center has received numerous prestigious awards and continues to advance as a model for sustainable commercial structures.
