Against abstractism, some architectural objects are apparently singular because historically and geographically contingent (Ingarden 1962); it is unclear what an experiential account of architectural abstracta looks like; and abstracta are not created whereas architectural objects are. De Clercq (2012) further proposes that, even if there were abstract architectural objects, we don’t refer to them. If I refer to “10 Downing Street”, my expression picks out the built structure, not the plan, nor any other abstract representation or entity to which the built structure at 10 Downing Street corresponds. However, a plausible alternate interpretation of the referent is as “the abstract object physically instantiated by the structure I am perceiving (or have perceived)”.
