The frame of a building delineates its structure. It comprises such an integral component of the whole that buildings are often referred to as "structures." The frame is so salient, essential, and defining that it is the major element represented in a building's blueprint or layout; it is the feature of that most readily lends itself to depiction. However, although it lends coherence and order to the finished product, the frame is by no means equivalent to the building as a whole.
