Some architects have a signature style. What sets Piano apart is that he applies his coherent set of ideas in extraordinarily different ways. It takes more than a quick glance to see his touch on such individual structures as the Pompidou Center, The New York Times Building in New York, and his 72-story London Bridge Tower.Each project is a renaissance, because, as Piano himself explains: “One of the great beauties of architecture is that each time, it is like life starting all over again.”
