Beyer Blinder Belle’s 2008 plan for Princeton is worth looking at. (Incidentally, what looks like Princeton’s prior plan of 1993-1996 was produced by Machado & Silvetti.) General observations on Princeton made after skimming the plan:

• Princeton and Dartmouth are surprisingly similar in size. Princeton has 5,100 undergrads and 2,500 professional and graduate students in four schools: engineering, architecture, public affairs, and a graduate college. Dartmouth has 4,100 undergraduates and 1,900 professional and graduate students in four schools: engineering, medicine, business, and group of graduate programs.
• Princeton’s compact, uniform block of a site emphasizes how much of Dartmouth is made up of reserved landscapes, whether green, park, cemetery, or slope. Princeton also has a vast unused land bank on the other side of the narrow lake that forms its south edge.
• Princeton’s ten-minute walking radius is centered on the student center, not the main library, central quad, or old main building.
