Northfield – Northfield is a tight knit community with just 5,500 residents. Like most small communities in the Chicago area, this means that Northfield is especially exclusive and luxurious. The location offers some of the largest lot sizes of any suburb of Chicago. Although residents have plenty of privacy, the access to Interstates 94 and 294 along with downtown Chicago is unprecedented. All North Shore properties pride themselves on top tier landscaping, but Northfield seems to set the bar for the rest of Chicago.
