When the initial designs for the Daniel Libeskind addition to the Denver Art Museum were unveiled, there were the jagged Hamilton Building, the canted Museum Residences, the blocky parking structure, and a hotel in the form of a vertical shaft at the southeast corner of the site. This tower was meant to serve as a bookend of sorts, linking the whole thing back to the Gio Ponti tower on the Civic Center, thus creating a harmonious whole. But financial times being what they were, the hotel was never built, and the Broadway face of the complex was marred by a plot of gravel, above which sat the blank wall of the garage. But ground has finally been broken for the building, which will be going up soon. Designed by Guadalupe Cantu, a former partner at Studio Daniel Libeskind and now at the Davis Partnership, the new building, the Museum Center + Art Hotel, will house offices on the lower floors and luxury hotel rooms on the upper levels.
