I hope that any expansion of London will learn from the planning examples of some of its most desirable areas such as Chelsea, Notting Hill, Belgravia and Mayfair. All are characterised by high density and a generosity of green spaces. They are all pedestrian-friendly with shops, entertainment, restaurants and pubs within easy walking distance.

I tend to move between turtlenecks and shirts and ties. I don't really have a uniform in the sense that some people might.

Every time I've flown an aircraft, or visited a steelworks, or watched a panel-beater at work, I've learned something new that can be applied to buildings.

As an architect you design for the present, with an awareness of the past, for a future which is essentially unknown.

I am always surprised by how much little emphasis schools of architecture, and indeed, many architects, place on the process of the mating of a building.

Google has already tested robot cars in San Francisco. If they can navigate San Francisco, they can probably manage just about anywhere.

I'm not a creature of habit. I like to find things from unexpected sources.
