PRO: Award-winning architect whose style has been praised for bridging the gap between architecture and engineering. He designed the new PATH train station at the World Trade Center site.
CON: His work is criticized as impractical—the airport he designed in Bilbao, Spain, lacks proper facilities, and the bridge connecting to nearby hotels is prone to cracking and gets slippery when wet.
