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

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.

In Britain, we've tended to replace the kind of architectural culture valued in much of Europe with an in-flight magazine lifestyle - all branding, marketing and 'accessibility', a word that usually means dumbing-down.

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.

There is a danger when every building has to look spectacular; to look like it is changing the world. I don't care how a building looks if it means something, not to architects, but to the people who use it.

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.

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.
