I was studying civic spaces. So I was studying the Campo at Siena. I was studying the main square in Verona, even Shepherd Market here in Mayfair, the great circus of Bath. So I was not just interested in buildings; I was interested in the civic settings for buildings, what we popularly call infrastructure, public space. I was also interested in anonymous architecture, what a scholar architect called Bernard Rudofsky was later to term “architecture without architects” — and created a very celebrated exhibition, I think in the 1960s, with a book of that name. So as a student, I was intrigued and fascinated by anonymous buildings, great barns, windmills, bridges. So my interest has always been broad and beyond buildings in isolation. It doesn’t mean to say that as an architect I’m not absolutely passionate about the design of an individual building. Of course I am. But I can’t separate that building out from its immediate environment, which may explain why, if you look at those buildings, any tall tower — the Hongkong and Shanghai Bank — it lifts it up. The public space flows underneath that building. If you take the Commerzbank Headquarters in Frankfurt, it engages with the city. There’s a shared restaurant for the citizens of the city and the occupants of the building. I could go on. So it’s more than just a building in isolation. The idea is that it should give something back to the community of which it’s a part.
