PRO: Pritzker-prize winner and co-founder of the Office for Metropolitan Architecture who questioned the "form follows function" maxim of the 20th century in favor of the concept of "Bigness."

CON: He is often criticized for ignoring all consideration for beauty and taste and straying too far outside the bounds of convention. Some of his most celebrated designs have still yet to be built.
