The Hyatt Regency Denver got off to an ignoble start when the old Denver Post Building, an art-moderne treasure by Temple Buell, was torn down to provide a site for a not-yet-lined-up hotel at the expanded Colorado Convention Center. But then things took a turn for the better when klipp, a Denver architectural firm, was hired to design it. The firm's team, headed by Brian Klipp, with Keat Tan acting as design architect, conceived of the hotel as a sleek, neo-modernist skyscraper made up of a series of vertical rectangular volumes that are clustered cubistically and soar to 37 stories. Since the hotel is city-financed, it has lots of publicly funded art; since it's a Hyatt, there are also privately purchased pieces. Jaded Denverites couldn't have expected this building to be the best new high-rise in a generation -- but we ought to be grateful that it is.
