During the conversion of this building back from offices to flats, archaeological observations were made of both the building and new service trenches, principally concentrating on features that revealed the original layout and use of the building during its use as an almshouse from the mid-19th to the mid-20th centuries. This included a digital photographic record before works began, and as plaster and partitions were removed. Features were marked up to scale on the architect's plans and a reconstructions made of each floor. Historical research further added to the understanding of the building and its uses. The service trenches were monitored but were largely unrevealing, The architectural fragments, formerly belonging to the Abbey of Peterborough, were recorded by the Cathedral Archaeologist The pre-works observations, combined with map regression and other research, showed (contra earlier suggestions) that the whole building was newly built in 1848. The different builds visible on the west side are the result of an earlier adjoining building, its removal, and the subsequent refacing of the west wall, below the gable. Documentary evidence, backed up by observations within the building, proves that there were eight almswomen housed here, six of them provided with a large room and a small subsidiary room or rooms, which might have functioned as a tiny bedroom, or storage; two of them did not have secondary rooms. Observations during the building works themselves added further information, such as the location of lost doors, the original appearance of the central ground floor passageway, and the identification of original windows and partitions. In short, far more survived of the original arrangements than previously thought. Below ground deposits exposed by trenching for a new foul drain produced evidence for wholesale demolition of the Victorian washhouse and reuse of its materials in the walls of the new extension; the trenches for gas electricity were less informative.
