Although prefabrication has a long history - the ancient Romans shipped pre-cut stone columns, pediments, and other architectural elements to their colonies in North Africa, where the numbered parts were reassembled into temples - the idea took on a new impetus with the technological advances of the Industrial Revolution.

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.

A turning point in the public's perception of the building art came with the publication of Frank Lloyd Wright's 'An Autobiography' of 1932, a picaresque narrative that captivated many who hadn't the slightest inkling of what architects actually did.

As with many other folk beliefs, 'feng-shui' undoubtedly incorporates some scientifically correct observation or received wisdom based on direct experience of natural phenomena; but it needs to be dealt with skeptically as a credible system of thought. Some feng-shui prescriptions can certainly lead to desirable results.

There is no sadder tale in the annals of architecture than the virtual disappearance of the defining architectural form of the Modern Movement - publicly sponsored housing.

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.

Elevated locations imply elevated purposes, even in American cities departing as radically as Los Angeles does from the traditional planning patterns of the Eastern Seaboard.
