Believe it or not, some people hate the main building of the Denver Art Museum, a silver-glass-tile-clad brutalist fortress designed by big-time Italian modernist Gio Ponti and completed in 1971, and over the years they've repeatedly suggested that it be demolished. Instead, DAM director Christoph Heinrich and the museum's board of trustees dismissed any thought of tearing it down, and instead decided to spruce up the place. The $150 million-plus project, which has just gotten under way, is being designed by Fentress Architects with Machado Silvetti and headed up by Jorge Silvetti, a lifelong admirer of Ponti; the plan is to fix what's wrong and add an adjacent pavilion intended to visually link the Ponti to the Hamilton Building across West 13th Avenue. Look for the revived Ponti to reopen in 2021, just in time for the building's fiftieth anniversary.
