The idea of type described in the discussion on the suburban office building in Chapter 3 acknowledges the conditioning influences on the type coming from function, image, technology, market, and culture. My description of this type is specifically analytical, a way of understanding the form and its process of formation and transformation without interjecting idealism or judgment. One may not consider this building type ideal or even acceptable, but exemplars do exist in great numbers, and thus the type has affected metropolitan form quite profoundly.
