The four communities of Ainsworth; the Bush, Millgate Cheltenham/South Chicago and Calumet quickly developed into one village referred to collectively as South Chicago during the wave of annexation in 1883. The predominantly woodframed architecture of the Bush, Millgate and eastern Cheltemham are a lesson in Victoriana with the 'sunken yards' and bridge-like walk ups from street like Houston, Baltimore and Brandon attesting to the degree infrastructure built up from the original topography of that time. It also demonstrates how South Chicago was not immediately affected by the housing ordinances restricting the use of lumber for home building after The Great Fire of 1871. Most of the neighborhood north of East 83rd Street and west of South Manistee Avenue was developed after WWII and contain mostly brick homes, but under the ordinance brick homes began being built throughout the newly annexed neighborhood after 1883.
