 This essay refers generally to the basic creative output of architects, in any (unspecified) form, as “architectural objects”. This is in parallel with the term “art objects” in use, across aesthetics and philosophy of art, to refer to objects created by artists independent of the artform and without regard to ontological or other discussions where other terms may evoke one or another particular stance. It may turn out that “architectural object” proves value-laden. Yet this is less likely than with common alternatives in the literature: “architectural works”, perhaps wedded to creator intent, status as extant or integral whole, or aesthetic ranking; or “buildings”, certainly wedded to built, hence concrete, structures.  “Built structures” is used here (except in historical reference) to refer to the generic built output resulting from architectural design, in recognition of a domain some view as broader than buildings per se.
