What is the key feature of the International style as seen in Chicago?

The key feature of the International style as seen in Chicago is functionalism and minimal ornamentation. This architectural style, which emerged in the 1920s and 1930s, emphasizes simplicity, clarity of forms, and the idea that the function of a building should dictate its design.

In the context of Chicago, the International style is characterized by its use of modern materials, such as glass and steel, allowing for open interior spaces and a seamless connection between the indoors and outdoors. The lack of ornate decorations is a hallmark of this style; instead of embellishment, there is a focus on the structural elements of a building, showcasing its functionality.

By embracing these principles, architects of the International style sought to create buildings that were not only aesthetically pleasing but also efficient and adaptable to modern urban life. This approach fundamentally influenced the skyline of Chicago, leading to iconic structures that exemplify the balance between form and function, making it a defining feature of the city's architectural identity.
