It served as the headquarters of the Mountain States Telephone & Telegraph Company, later known as Mountain Bell. Constructed in a variant of the Gothic Revival style named "Modern American Perpendicular Gothic," the building was designed by local architect William N. Bowman. The new building, completed in 1929, was built to provide dial telephone service for the first time in Denver.[2]

It is a 15-story building with buff-colored terra cotta, on a pink granite base. According to its NRHP nomination, the "Mountain States Telephone and Telegraph Company, the building's original owner, called its architectural style 'Modern American Perpendicular Gothic,' referring to its setbacks, massing, vertically, and Gothic Revival style ornamentation."[3] The Gothic Revival architecture of the Mountain States Telephone Building is featured on many of Denver's Architectural tours.[4][5]

The entrance of the building features 13 murals from the history of telecommunications by Allen Tupper True,[6][7] which were painted in 1929.[8] The murals are located at several of the entrance lobbies and in one location inside the building.[9]
