What material is commonly found in the construction of buildings in the Chicago School style?

The Chicago School style of architecture, which emerged in the late 19th and early 20th centuries, is characterized by its innovative use of materials and construction techniques that allowed for the rise of skyscrapers and the development of urban architecture in Chicago. Brick is a fundamental element in this style due to its durability, aesthetic appeal, and the historical context of Chicago's building practices.

Buildings from the Chicago School often featured brick facades, which offered thermal mass and were suitable for the city's climate. Additionally, brick allowed for decorative detailing and stylistic expression while providing structural support. This material became a hallmark of the style as architects sought to achieve both functional and visual aims in their designs.

While steel, concrete, and wood are also significant in various architectural contexts, the Chicago School notably utilized brick to create a harmonious yet robust appearance in its buildings, blending both traditional craftsmanship and modern innovations. Thus, the choice of brick is intrinsic to the identity of this architectural movement.
