A watching brief maintained by R Poulton and S Hind of SCAU, for Richard Cook Ltd, on the redevelopment of this 19th century mill site for offices, revealed no evidence for earlier mills; the area was found to have been fairly extensively disturbed as a result of 19th and 20th century works. However, palaeo-environmental analysis of sediments in former channels of the Wey, uncovered by the works, revealed evidence for increasing human activity in the vicinity from the Bronze Age onwards, with a commensurate reduction in the amount of woodland in the area.
