This is the only way to describe the diagramming efforts that have been shown here. It is almost ridiculous to see the attempt to find the golden rectangle in almost every building. Believe me geometrical nonsense as well as the "parti" was no where in the mind of FLW for Fallingwater. Similarly the critical agenda as well as the main "idea" of the building is a whole lot richer and important than seeing symmetry and axes. My million $$ question is how does the participant in any space percieve that axis shown when he is more immersed in the feeling of the architecture? I guess that this mumbo-jumbo stopped at Venturi as I havent seen any "analysis" (save critical and existential) of Holl, or HDM or Ito or Koolhaas or Eisenmann or anyone of the Avant Garde.
Stay away from this book if you want to learn anything about architecture.
