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 think you never stop learning.

Manhattan, one of the most moneyed spots on the planet, also has one of the greatest concentrations of people in its skyscrapers. Its also, of course, the place where every architect wants to build his tower.

You cannot separate the buildings out from the infrastructure of cites and the mobility of transit.

Since Stonehenge, architects have always been at the cutting edge of technology. And you cant separate technology from the humanistic and spiritual content of a building.

Everything inspires me; sometimes I think I see things others don’t.

It takes a lot of effort to make a building look effortless.
