Family is everything, although I've been fortunate enough to have worked with some of the most amazing minds over the years, including Renzo Piano, John Young, Graham Stirk and Ivan Harbour.
I cycle, which is a healthy thing for an 80-year-old to do. I rarely go further than five miles, but in those five miles I can get to 80 percent of the places I want to go.
You know, the environment is fragmenting, and the environment is, in many places, absolutely hideous!
I believe very much in a dialogue between buildings - I believe it's always been there. I think buildings have different identities and live very well next to each other. We always have the shock of the new, and that's fine. The renaissance style is totally different from the medieval, and they have a dialogue across time.
Cities are about juxtaposition.
My architecture tends to be legible, light and flexible. You can read it. You look at a building, and you can see how it is constructed. I put the structure outside.
Cities depend on a healthy mix of uses and people for their vitality. As a pre-eminent world city, London is a magnet to people from across the globe.
You have to modernise; you have to change - you can't just be traditional for the fun of being traditional.
I love cities, I spend most of my life talking about cities. And the design of cities does have an effect on your life. You're lucky if you can see trees out of your window and you have a square nearby, or a bar, a cornershop, a surgery. Then you're living well.
There is no one-size-fits-all solution to the challenges facing our cities or to the housing crisis, but the two issues need to be considered together. From an urban design and planning point of view, the well-connected open city is a powerful paradigm and an engine for integration and inclusivity.
A greater focus on design in all new homes would make the best use of land, create homes and public spaces, and reinforce the structures of urban life.
Architecture is a slow business, and city planning even slower.
I like the idea of trying to influence society by taking a brief, then maybe subtly changing it or looking at it in a new way to see what interesting things can emerge.
Everyone has the right to walk from one end of the city to the other in secure and beautiful spaces. Everybody has the right to go by public transport. Everybody has the right to an unhampered view down their street, not full of railings, signs and rubbish.
If you had a carbon tax, you'd have less cars and more bicycles, more people getting around on foot and by public transport.
The gap between the rich and poor is widening fast.
