And exciting buildings are fine periodically.

I have been criticized rather strenuously by painters and sculptors for not incorporating their work in our buildings.

We build buildings which are terribly restless. And buildings don't go anywhere. They shouldn't be restless.

But now I know that it is very important that all buildings should be consistent, that this is the quality of the Gothic cathedral, for instance, that we like.

So what we have tried to do in our later buildings is to try to be completely consistent, as a painter is consistent or as a sculptor is consistent. Architecture also must be very consistent.

If you look at the buildings, you'll find that one part looks as if it was designed by one man, and you go around and look at another facade and it looks as if it was designed by another man, you see.
