AI Overview

O'Fallon is one of Missouri's largest cities and a popular landing spot for families moving into St. Charles County. Homes here are served by the Fort Zumwalt and Wentzville school districts. New construction is common, and prices generally run from about $350K to $475K at the median. WingHaven and Highway K bring major shopping and dining, and the parks system is strong. I-64 and I-70 are close. Downtown St. Louis is a 35 to 45 minute drive, and Lambert Airport is about 25 minutes away.
