Great Linford Parish consists of 12 estates with a variety of activities. Tongwell is the only non-residential estate.
Wikipeadia quote: "Tongwell is a district and ancient hamlet in the civil parish of Great Linford (where at the 2011 Census the population was included) in Milton Keynes, England.
Historically, it was in the parish of Newport Pagnell but today it is separated from Newport Pagnell by the M1 motorway and has become part of Milton Keynes. Just a few farms remained before the land was built on. It is now an industrial area.
Numerous companies operate from Tongwell such as Dawson Group, Mercedes-Benz UK and Volkswagen UK."
