It is my belief that exciting things happen when a variety of overlapping activities designed for all people-the old and the young, the blue and white collar, the local inhabitant and the visitor, different activities for different occasions-meet in a flexible environment, opening up the possibility of interaction outside the confines of institutional limits. When this takes place, deprived areas welcome dynamic places for those who live, work and visit; places where all can participate, rather than less or more beautiful ghettos.

Technology cannot be an end in itself but must aim at solving long term social and ecological problems.

Architecture is measured against the past, you build in the present, and try to imagine the future.

Sustainable development: Meeting present needs without compromising the stock of natural resources remaining for future generations. In terms of buildings, it implies resource efficiency, minimum energy use, flexibility and long life

Architecture is a slow business, and city planning even slower.

There has to be policies about that, about what materials we use and so on.

I'm just saying that there are high quality materials, and when we change them then there should be a way of changing them so that you can celebrate that change - rather than just 'mix it up'.
