Three subdivisions east of Pulaski led to the development of the area in the late 1890s. West Walker is located between Montrose Avenue and Irving Park Road and is characterized by large single family homes in late Victorian, Foursquare and Revival styles. The area south of Irving Park Road was developed by Samuel Gross and was known as "Gross Boulevard addition to Irving Park". The housing stock is similar to that of West Walker. The section between Addison and Avondale was developed as the "Villa addition to Irving Park" and contains many unique Craftsman and Bungalow style homes fronting on boulevard style streets. The Villa District, as it is known, is a Chicago Landmark district, dubbed by hallowed journalist Mike Royko as ""Polish Kenilworth"" due to its heavily ethnic hue.
