Because architecture, like other art, cannot be made on demand, like shoes or hats, it is pointless and utterly doomed to attempt any global definition of it by any means whatsoever unless one is willing to degrade the term to any to fit building effort.
The one aspect of architecture that is good to trace is the evolution of architectural style because it develops slowly over a long period of time and with luck one can find evidence of its various stages. Again, let it sink in, architecture cannot be made on demand. WC The necessary condition sufficient and efficient enough to make an architecture art is seemingly not yet clearly defined. Consider furthermore that all drawings are pictures, but that not all pictures are drawings, so that therefore while all buildings are architectures, not all architectures are buildings.
