Evaluation by E Eastbury of MoLAS prior to redevelopment found that most of the site had suffered severe truncation of any potential deposits during the construction of the existing buildings. A small area was found to contain a deep feature, containing stratified material dating from the Late Neolithic to Roman periods. Owing to the large size of the feature, its extent or exact nature could not be verified. A subsequent watching brief on the area where the feature was presumed to continue provided no further information.
