Historic building survey by Dr E Oakley for AAL (Allen Archaeology Ltd) revealed an L-shaped block of one- and two-storey brick buildings, with four broad phases of development identified. The earliest component represented buildings established c 1868 as part of the Filmer and Mason Ironworks. By 1881 the site was known as Church Acre ironworks and a number of small extensions were added in the period 1881–96. The ironworks ceased operation in the 1920s and the site was later occupied by the army.
