One of the stated goals of the postmodern movement in architecture was a greater sensitivity to the people who live in or use newly designed buildings.

Cost overruns are not uncommon in architecture, particularly for designs that depart from structural or technological norms, or demand a finer quality of execution than commercial schemes - conditions typical of buildings for cultural institutions. Budgets are exceeded for many reasons, not all of them within an architect's control.

Architecture traditionally has been the slowest of art forms. It was not unusual for great cathedrals to take centuries to complete, with stylistic changes from Romanesque to Gothic or Renaissance to Baroque as common as the addition of chapels or spires. But because the function remained the same, the form could be flexible and its growth organic.

The popular mythology of creative genius depends on beloved stereotypes of the artist in youth and old age: the misunderstood upstart who forces us to see the world afresh; and the revered sage who shows us depths of insight attainable only through a lifetime of hard-won experience.

Any set of decisions about design is inevitably influenced by cultural prejudice, no matter how intent an architect might be to avoid it.

The work that launched Snohetta into the architectural big leagues was their Oslo Opera House, which will certainly rank among the firm's highlights whatever else they may do. Although this is by any measure a triumph of city planning, the building itself is not quite a masterpiece, though very fine indeed.

Avant-garde architects have never been able to depend on the support of the establishment, since the customary patrons of this most conservative and slowly moving art form have historically been resistant to innovation and experiment.
