Variants of architectural formalism take formal properties as the properties of (or arising from) the material or physical properties of built structures (as consonant with concretism), or as the properties of (or arising from) the total properties specified by a set of formal parameters we identify with the architectural object (as consonant with abstractism). Further architectural strains are characterized by moderation (per Zangwill 2001), suggesting that some architectural objects are best understood by appealing to their formal properties, others not; or by assimilation of canonically non-formal properties to a formalist scheme (in the manner of Levinson’s “indicated structures”; see S. Fisher 2000b); or by a “mereological” view wherein some parts of a given architectural object may be best understood and judged by their formal properties, others not. For the merelogico-formalist, it might count in favor of considering such parts as independent architectural objects that we can judge those parts on a formal basis alone.
