The delightfully bizarre plan for inflating a seasonal bubble in the middle of the Hirshhorn Museum that bulges out one side, creating spaces for an auditorium and cafe, has picked up Architect magazine’s 58th Annual Progressive Architecture award. The American Institute of Architects’ in-house rag selected the Hirshhorn along with a border control station in Maine out of more than 300 entries, and included a few nifty renderings I hadn’t seen before, which give an idea of what the confection will look like from the inside as well as out.
