What is good architecture? The answer is as complex as the question is simple. 'OASE' investigates the assumptions behind existing value models by having the question 'what is good architecture?' answered by people whose 'preoccupation' is architecture. Although architecture is the subject of much writing and debate, architects, critics and historians seem to assume that an unequivocal value model for architecture does not exist. Moreover, the last models for architecture evaluation (modernism and postmodernism) have been followed by perversions (supermodernism, retromodernism) or by science-focused ideals (sustainability, computing models). Yet many problems in the world of architecture would disappear if what is meant by 'good architecture' were made clearer.
