Excavation by R Poulton of SCAU, for the Equitable Life Assurance Society, of the upstand at the rear of these buildings followed trial pitting by the GMVEU. Much modern disturbance was revealed but a number of 12th/13th/14th century pits survived. One such pit, of 12th/13th century date, appeared to be sealed by chalk rubble, which is presumed to be debris from the partial demolition of the medieval chamber below these properties. (321)
