Denver Gas & Electric Building

The Denver Gas & Electric Building, also known as the Public Service Building, the Insurance Exchange Building, and IX-West , is a building located in the downtown district of Denver, Colorado. Designed by architect Harry W. J. Edbrooke for the Denver Gas & Electric Company, the 10 story building was completed in 1910.
