High among the unpredictable variables that endanger the survival of worthy buildings are the vagaries of taste.

Considering my specialization in architecture, I'm not surprised that the first graphic novel to thoroughly engage, not to say captivate, me is Chip Kidd and Dave Taylor's 'Batman: Death by Design.'

The danger for any artist whose work is both recognizable and critically acclaimed is complacent repetition - the temptation to churn out easily identifiable, eagerly welcomed, and readily salable designs.

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.

The most basic task of any museum must be the protection of works of cultural significance entrusted to its care for the edification and pleasure of future generations. This imperative rightfully takes precedence over acquisition, interpretation, outreach, or any number of other activities now believed to be crucial to the survival of our great art repositories. Sometimes a museum gains its holdings with much strategic forethought, and at other times serendipitously, as when a long-coveted neighbor’s plot suddenly becomes available. Yet the moral responsibility remains the same.

One of the most persistent yet elusive dreams of the Modern Movement in architecture has been prefabrication: industrially made structures that can be assembled at a building site.

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.
