The modern architecture that I have been weaned on also espouses (clear) function, (exposed) structure, and (raw) material as principles—characteristics that tend to be accessed only from realistic or substantive dimensions. Fictionality or imagination, the other dimension, is omitted entirely. However, Vitruvius emphasized venustas, in other words attraction or beauty as a necessity along with strength and function.
