First Chicago School

While the term "Chicago School" is widely used to describe buildings in the city during the 1880s and 1890s, this term has been disputed by scholars, in particular in reaction to Carl Condit

, Winston Weisman and Daniel Bluestone have pointed out that the phrase suggests a unified set of aesthetic or conceptual precepts, when, in fact, Chicago buildings of the era displayed a wide variety of styles and techniques.

Some of the distinguishing features of the Chicago School are the use of steel-frame buildings with masonry cladding (usually terra cotta

The "Chicago window" originated in this school. It is a three-part window consisting of a large fixed center panel flanked by two smaller double-hung sash windows. The arrangement of windows on the facade typically creates a grid pattern, with some projecting out from the facade forming bay window
Bay window
A bay window is a window space projecting outward from the main walls of a building and forming a bay in a room, either square or polygonal in plan. The angles most commonly used on the inside corners of the bay are 90, 135 and 150 degrees. Bay windows are often associated with Victorian architecture...

Tube (structure)
In structural engineering, the tube is the name given to the systems where in order to resist lateral loads a building is designed to act like a three-dimensional hollow tube, cantilevered perpendicular to the ground. The system was introduced by Fazlur Rahman Khan while at Skidmore, Owings and...

 as "a three dimensional space structure composed of three, four, or possibly more frames, braced frames, or shear walls, joined at or near their edges to form a vertical tube-like structural system capable of resisting lateral forces in any direction by cantilevering from the foundation." Closely spaced interconnected exterior columns form the tube. Horizontal loads, for example wind, are supported by the structure as a whole. About half the exterior surface is available for windows. Framed tubes allow fewer interior columns, and so create more usable floor space. Where larger openings like garage doors are required, the tube frame must be interrupted, with transfer girders used to maintain structural integrity.

The first building to apply the tube-frame construction was the DeWitt-Chestnut Apartment Building which Khan designed and was completed in Chicago
