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.

Before World War II, Modernist architects sometimes had to resort to custom fabrication or outright fakery to achieve the machine imagery advocated by the Bauhaus after its initial, Expressionist, phase. Stucco masqueraded as reinforced concrete; rivets were used for decoration.

When Oscar Niemeyer died on December 5, 2012, ten days before his 105th birthday, he was universally regarded as the very last of the twentieth century's major architectural masters, an astonishing survivor whose most famous accomplishment, Brasilia, was the climactic episode of utopian High Modern urbanism.

Experimental architecture by its very nature is more prone to the depredations of time and natural elements than buildings made from conventional materials through traditional methods. Avant-garde architects often simply do not know how the products of their imagination will perform when implemented, especially if untested components are involved.

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.

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.
