A watching brief was maintained by J Stevenson of SCAU, for Epsom and Ewell Borough Council, during the construction of a new access road and car park for the Town Hall in Epsom. A post hole of possible medieval date was found, as well as chalk block foundations with remnants of the original mortared flint walling and associated mortared tile floor. Historical references show a cottage and barn on the site in 1680, which became known as Cromwell House in the 18th century. It seems likely that the remains encountered form part of the earliest phase of this building.
