Architecture is about public space held by buildings.

Architects design buildings; that's what we do, so we have to go with the flow; and, even though I'm still an old Leftie, global capitalism does have its good side. It's broken down barriers - the Berlin Wall, the Soviet Union - it's raised a lot of people up economically, and for architects, it has meant that we can work around the world.

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.

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.
