Since the Bilbao Guggenheim opened, no museum can afford to be blase about getting bigger. “Today, no museum Web site worth its salt is without a section on its imminent, or just completed, ‘expansion,’ ‘renovation,’ ‘renaissance’ or ‘transformation.’ The rhetoric is eerie in its uniformity: The new building will display the museum collection in a ‘fundamentally new way.’ It will provide the public with a ‘richer and deeper experience.’ It will be an ‘exciting new public space.’ And, of course, the café and bookstore will be expanded.” Architect Moshe Safdie has come along with a kind of “anti-Bilbao” approach to museum-building.
