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.

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.

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.

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.

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.

Masterpieces of art possess immense potential to advance a worldview that could help assuage the societal terrors posed by globalization, the most thoroughgoing socioeconomic upheaval since the Industrial Revolution, which has set off a pandemic of retrogressive nationalism, regional separatism, and religious extremism.

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.
