Cities are the greatest creations of humanity.

The truth is, the way you write music, it's a code. It has to be very precise. It's scientific, but ultimately it also depends on interpretation. It's very similar to how you grow a master plan: it's an objective document, but at the same time it is a lyrical document which allows through interpretation to become a harmonious work of art.

Don't look at the superficial success, at the short-term success. Look at the deep spiritual questions that architecture has to answer. Who do you build for? Where? What should you build?

We live in a time of renaissance ... cities are coming back to life, after a long neglect.
