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.

I may not be the most interesting architect, but I'm still out there and have maintained some position of integrity.

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.

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

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.

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.
