A city can only be reconstructed in the form of urban quarters. A large or a small city can only be reorganized as a large or a small number of urban quarters; as a federation of autonomous quarters. Each quarter must have its own center, periphery and limit. Each quarter must be a city within a city.

All buildings, large or small, public or private, have a public face, a facade; they therefore, without exception, have a positive or negative effect on the quality of the public realm, enriching or impoverishing it in a lasting and radical manner. The architecture of the city and public space is a matter of common concern to the same degree as laws and language—they are the foundation of civility and civilisation.

For architecture, nature provides only indications and analogies, not models to imitate.

The rigidity of a bottle's form does not affect the fluidity of the liquid it contains.

Horizontal and vertical sprawl... are the dinosaurs of an ending fossil-fuel age of synthetic culture.

Lots of English people say exactly the opposite of what they mean.

I don't build because I am an architect. I can make true architecture because I do not build.
