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.

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 magnificent lobby of the Chrysler Building - faced with rare marbles, aglitter with decorative metalwork, and surmounted by a ceiling painted with a totemic image of the tower itself - leads to elevator cabs inlaid with exotic woods in fanciful patterns. The entire route from street to office is invested with ceremony, dignity, and delight.

The financial benefits of prefabrication have never been as large as its advocates predicted, for although some labor costs can be reduced by machine manufacturing, on-site assembly of any building still depends to some extent on the handwork of skilled craftsmen.

During the modern period, the vanguard architect has usually relied on small residential jobs both to supply a steady income and to serve as 'sketches' for ideas that are often later translated to the larger scale of public commissions.

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

Always beware an unsigned architectural design.
