In the 1990s Denver voters approved a $91.6 million bond issue to add onto the Fisher/Hoyt building; the new structure, designed by the 2012 Driehaus Prize winner Michael Graves and the Denver firm of Klipp Colussy Jenks DuBois, opened in 1995. The seven-story exterior is finished with limestone and pre-cast concrete with copper accents throughout. Murals are painted inside by the artist Edward Ruscha and fossils are embedded in its floor within the Schlessman Hall. There is also an art gallery within the Level Five Gates Western History Ready Room.
