“One of the most persistent images in American urbanism is that of the proverbial…” — Martin Filler

There can be little question that the tall building presents one of the most difficult challenges to the architect.

The skyscraper style first advocated by Louis Sullivan - a tower of strongly vertical character with clear definitions among base, shaft, and crown - has remained remarkably consistent throughout the history of this building type.

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.

Any set of decisions about design is inevitably influenced by cultural prejudice, no matter how intent an architect might be to avoid it.
