Evaluation by H Clough of PCA in advance of the construction of a workshop extension revealed two ditches of probable Bronze Age origin, a palaeochannel which may be prehistoric, medieval agricultural features, a late 18th or early 19th century wall, and residual burnt and worked flint, abraded Roman pottery and a piece of unabraded Saxo-Norman pottery. Subsequent monitoring of two geotechnical test pits within the proposed footprint of the workshop revealed only modern deposits.
