Ennead Architects (formerly Polshek Partership) seems to be taking over Stanford University one building at a time. First they built the Cantor Center for the Visual Arts in 1998. Then they finished the Stanford Law School Academic Building in 2010. They were also commissioned to build the Bing Concert Hall, which will open in 2013. And now they’ve just been chosen to build a $30.5 million, 30,000 square foot building for the Anderson Collection, a renowned compilation of post-World War II American Art. The building will also contain a library, offices, and storage spaces. Designs for the project will be released this Spring, according to Stanford. The Anderson, the Bing, the Cantor, and the new 96,000 square foot Burton and Deedee McMurtry Building, awarded in April to Diller Scofidio+ Renfro and containing undergraduate art and film studios, galleries, and an art and architecture library, will form the center of Stanford’s “arts district.”
