SECOND, raise your normal view and look up as you walk around. Much of the architect’s effort is above eye level. See how the light hits the surfaces. Notice the shape of the shadows. Notice the number of layers in the façade, starting with the layers of mass closest to you and receding to the window glass. Focus, in turn, on color, form, texture, proportion, rhythm, silhouette, mass. Look only for form for a bit, then look only for proportion, then the other elements of design—each in its own time.
