“Procession: Ascent” and “Scale: Respect & Experimentation” are also Johnson Principle highlighted in the design team’s research. Ascent is about celebrated vertical circulation. Johnson said, “But really, the atrium is not an atrium: it’s the center of nine squares. It’s the idea of communication, like McKim’s. My atrium isn’t as nice as his. Well, his is a court. Mine isn’t a court or even an atrium; it’s too small. It’s a stairwell. But it’s still an orientation point.” He also said, “I don’t remember where the elevators are hidden, but they’re meant to be hard to find; that way you’re compelled to take the stairs.”
Respect and Experimentation are about past and future. Johnson said, “My principle was that the cornice line is sacred; the material is sacred…we have to do modern scale…out of keeping… as long as it doesn’t insult McKim.”
