Bannockburn is a village in West Deerfield and Vernon townships in Lake County, Illinois, United States. The population was 1,583 at the 2010 census. The village is generally considered part of the Chicago area's North Shore region. The Friedman house by Frank Lloyd Wright is located in Bannockburn.
Bannockburn was founded by Scottish real estate developer William Aitken, who planned a community of "country estates" on 110 acres (0.45 km2) in inland Lake County. Named for the Scottish village of Bannockburn, the village began construction in 1924 and was incorporated in 1929. Aitken designed his development for the affluent members of his bridge and country club. His plan for Bannockburn featured large lots to imitate country living, and this design has been preserved; in fact, the original 1-acre (4,000 m2) minimum on home lots has been increased to two.
Gradually, Bannockburn expanded its boundaries to its current 1,318 acres (5.33 km2). The Tri-State Tollway was built through the village in the 1950s, encouraging growth, though traffic noise pollution has been a persistent local concern. In the late 1960s Bannockburn's citizens, after some debate, approved the construction of the first of several business parks along the village's northern edge.
