NBC Chicago’s December 2023 roundup of the film’s suburban ties, citing Pioneer Press, names Chestnut Court in Winnetka, Illinois, as the Santa’s workshop location in Home Alone (1990). It is a small brick-paved area next to Village Hall.
This detail rests on a single news report, so treat it as reported rather than independently confirmed.
