Question

Quizplus · Accepted Answer

The steel-cage frame was a defining feature of the "Chicago-style" skyscrapers, including Sullivan's Wainright Building. This construction technique allowed for taller and more stable buildings, as well as the expressive use of exterior ornamentation. Exoticism, post-impressionism, and iron-and-glass construction are not directly associated with this architectural style.
