What defines the International style of architecture?

The International style of architecture is best defined by its clean and minimalist design characterized by a lack of ornamentation and a focus on functional form. This style emerged in the early 20th century and is marked by the use of new materials such as glass, steel, and concrete, which allow for open spaces and extensive use of glass to create transparency.

Visible frames are a significant feature of the International style, as they highlight the structure's skeletal framework and emphasize the building's functionality rather than decorative elements. This approach reflects the ideology of the movement, stressing simplicity and the idea that form should follow function. The emphasis on horizontal and vertical lines, along with flat surfaces, further contributes to the minimalistic aesthetic associated with this architectural style.
