What is a defining feature of a Chicago window?

A defining feature of a Chicago window is its distinctive design, which typically consists of a large central pane of glass surrounded by smaller, divided windows on either side. This feature not only contributes to the aesthetics of a building but also allows for greater natural light and ventilation, which were important considerations in the urban environment of Chicago. The central large pane enhances the view and creates a sense of openness, while the smaller flanking windows provide balance to the overall design.

This architectural style emerged in the late 19th and early 20th centuries, reflecting both the technological advancements in glass manufacturing and the aesthetic preferences of the time. The Chicago window is especially prevalent in residential and commercial buildings from that period, capturing the unique spirit of the city’s architectural evolution.
