The San Francisco Museum of Modern Art (SFMOMA) announced today its selection of Snøhetta to design its $250 million expansion. Until recently, the 100-person architectural firm has remained fairly under the radar in the United States, having completed major cultural projects only in such faraway places as Egypt and Norway. Today’s news, along with a string of North American projects by Snøhetta currently in development or under construction, is sure to change that.
