I am equally proud of all of my architectural projects. It's always rewarding to see an ambitious design become reality.

There are so many great galleries and museums in London, but they can be very crowded during the day.

I'm trying to discover - invent, I suppose - an architecture, and forms of urban planning, that do something of the same thing in a contemporary way. I started out trying to create buildings that would sparkle like isolated jewels; now I want them to connect, to form a new kind of landscape, to flow together with contemporary cities and the lives of their peoples.

There is a strong reciprocal relationship whereby our more ambitious design visions encourage the continuing development of the new digital technologies and fabrication techniques, and those new developments in turn inspire us to push the design envelope ever further.

I don't think people should do things because you know, 'I am turning this age, I must go have a husband.' If you find somebody and it works out then have kids, it's very nice. But if you don't, you don't.

You have to be very focused and work very hard, but it is not about working hard without knowing what your aim is!

The idea for a building or an object can come up just as quick, but there is a big difference in process.
