An architect's most useful tools are an eraser at the drafting board, and a wrecking bar at the site.

Form follows function - that has been misunderstood. Form and function should be one, joined in a spiritual union.

Architecture is essentially Human; it is the Human spirit manifesting itself. For when a Man builds, there, you've got him; you know exactly what, who and how that Man is.

Human beings can be beautiful. If they are not beautiful it is entirely their own fault. It is what they do to themselves that makes them ugly.

Every great architect is - necessarily - a great poet. He must be a great original interpreter of his time, his day, his age.

If you tilt the whole country sideways, Los Angeles is the place where everything loose will fall.
