A new building for Yale’s School of Management designed by Norman Foster was formally opened on January 9. New B-school facilities are sprouting like ragweed, not only in the United States but globally. The reason is not hard to find. Their alumni are among the richest on the planet, and demand for MBAs and business degrees has skyrocketed. The best schools want to improve their facilities; the newcomers want to jump on the bandwagon, and a fancy new building helps to attract students. Virtually all of these buildings are the work of prominent architects such as Norman Foster (Imperial College, London), David Chipperfield (HEC, Paris), and David Adjaye (Skolkovo, Moscow). The go-to firm in the U.S. is Robert A. M. Stern Architects, which has designed no less than a dozen B-schools, including at Harvard, the University of Virginia, and Rice. Most RAMSA business schools are traditional in style, although several (Drexel, Penn State, Ithica College) are best described as transitional—modern but not too modern. Berkeley (Moore Ruble Yudell) and Temple (Michael Graves) built PoMo buildings, although few B-schools have followed their lead. Most have opted for traditional, transitional (KPF at Wharton and Michigan), or mainstream modern (Rafael Viñoly at the University of Chicago and the University of South Carolina). KPF is edgier at Florida International and Arizona State, Enrique Norten is cooly minimalist at Rutgers. And Frank Gehry is Frank Gehry at Case Western Reserve. Not to be outdone, Columbia’s B-school announced that Diller, Scofidio & Renfro, darling of the critics, will design their new home. For a while, RAMSA set the pace with its traditional designs, but Foster at Yale may signal a new design trend among B-schools. The classrooms are contained in drum-like volumes that surround an enclosed courtyard, creating the impression of an elegant high-tech watering hole. A fitting lair for the wolf pups of Wall Street.
