On why he maintained a small practice

"Architecture is a personal effort, and the fewer people coming between you and your work the better. This keeps some people from practicing architecture, like the sculptor Nivola [Constantino Nivola, 1911-1988], who says "I cannot stand anybody coming between me and my work." This is a very real problem, and you can only stretch one man so far. The heart can fall right out of a building during the production of working drawings, and sometimes you would not even recognize your own building unless you followed it through. If an architect cares enough, and practices architecture as an art, then he must initiate design; he must create rather than make judgments."
