"You go back to age-old principles. I think there are definite and definable theories on how to relate volume to volume, mass to mass, texture and scale; the relationship of a building to the ground, to the sky, to neighbors. I really believe that you can define X number of approaches. The problem is to see that the approach is consistent, that each component part belongs to the same family of ideas."
