From “Good Architecture“:
In ‘building architecture’, for comparison, we have the 3 classic Vitruvian qualities to which ‘GoodArchitecture’ aspires:
‘Firmitas, Utilitas and Venustas’ (Marcus Vitruvius Pollio ‘The Ten Books of Architecture’ 1st C AD).
These qualities may be translated as: ‘Technology, Function and Form’ (C St J Wilson ‘ArchitecturalReflections?; Studies in the Philosophy and Practice of Architecture’ 1992 ISBN 0-7506-1283-5
or, in the slightly more familiar but antique: ‘Firmness, Commodity & Delight’
