Named for the simple fact that Denver Squares contain four square rooms on the first floor and four square rooms on the second floor, this style abounds in Denver. Most were constructed following the Silver Crash in 1893 during which the trend in design was toward less ornate and more serious architectural styles.

The space between the second floor windows was commonly used to ornament the plain style with decorative brick or terra cotta panels. Later, more variation was added to the Denver Square style with some examples in the city even possessing towers, Mission Style parapets, and Italianate influences.

Found throughout the city, one of the best blocks to explore examples of the varied interpretations of the Denver Square is the 1300 block of Milwaukee Street.
