Most architects work in ­studios largely divorced from academia, as if ideas, criticism and ­historical ­research were irrelevant.

It used to be presumed that if you weren't at your desk working, you weren't working. But we said, why can't we make a workplace where casual meetings are as important as working at your desk? Sometimes that's where your better creative work happens.

Often architects work too hard trying to make their buildings look different. It’s like we’re actors let loose on a stage, all speaking our parts at the same time in our own private languages without an audience.

I think that the point of being an architect is to help raise the experience of everyday living, even a little. Putting a window where people would really like one. Making sure a shaving mirror in a hotel bathroom is at the right angle. Making bureaucratic buildings that are somehow cheerful.

I spent more than ten years working on the Neues Museum. It was a wonderful experience, an example of real collaboration between architects, conservationists, curators, client, politicians, the media, and the public. Discussions, even when difficult, were always about ideas. Ideas matter to Germans. They're a reflective people. That's attractive.

You don't restore 'The Last Supper' by filling in the missing bits - you preserve. You accept the material that has somehow survived.

Britain gets the architecture it deserves. We don’t value architecture, we don’t take it seriously, we don’t want to pay for it and the architect isn’t trusted.
