Guaranty Building

A tall steel frame wrapped head to foot in red terracotta, every inch alive with Sullivan’s ornament.

At a glance

The Guaranty Building, finished in 1896, is one of the great early skyscrapers by Dankmar Adler and Louis Sullivan. Thirteen storeys of steel frame are sheathed in red terracotta covered, top to bottom, in Sullivan’s flowing foliate ornament. It is a built argument for his belief that a tall building should rise, and look as though it rises.

History

Sullivan had set out his ideas in an essay on the tall office building as a problem of art, not just engineering. The Guaranty, built for a Buffalo company, was his chance to prove them at full height.

He stressed the verticals with continuous piers, capped the top with a deep ornamented cornice, and covered the terracotta in his own organic patterns. Restored after years of neglect, it stands as a textbook of the early skyscraper.

What you see

The tower reads as a single upward gesture: tall piers running unbroken to a band of round windows and a rich cornice. Look closely and every surface is worked, the terracotta swirling with leaves and seed-pods. It is steel-age engineering dressed in nature, Sullivan’s answer to European Art Nouveau.
