The International style was developed in the 1920s by European architects in search of a style suitable for a modern society. Many American architects learned of the style through an influential exhibit in 1932, at New York City's Museum of Modern Art. There are few pre-World War II examples in Chicago--most were built after 1950--although a handful can be found in Hyde Park, South Shore, and West Town.

Common characteristics are:

• horizontal proportions
• emphasis on broad, flat walls
• lack of ornament
• windows wrapping around corners
• flat roofs
