The Shield Hall buildings complex principally comprises a 19th-century farmhouse on the west side of three ranges of farmbuildings arranged around a central yard which is open to the south. Historically and architecturally the most significant part of the complex is the north part of the West Range which probably represents the cross-wing of a 13th century house. A programme of historic buildings recording, carried out prior to, and during development works focused on the West Range, and was followed by several phases of archaeological works which included investigatory test-pitting, monitoring of built fabric during demolition works and monitoring of groundworks. The consolidation and refurbishment work reported here involved minimal disturbance to the existing fabric of the standing buildings, but small patches of the subsiding north wall were removed and replaced in order to arrest cracking and subsidence, while a first-floor section of the west wall of the 19th century barn was removed for the insertion of a new window. No significant observations were made during this process either concerning structural features or worked stones removed from the standing fabric. The principal interventions, however, occurred at and close to the intersection between medieval and 19th-century components of the west wall where two exploratory interventions preceded the unblocking of an inserted doorway, presumably of 19th century date, in order to create a connecting doorway between the farmhouse and refurbished West Range. This process resulted in the exposure of quoins at the end of a section of walling, oblique to both the internal faces of the medieval and 19th-century phases of the west wall, which joins the original medieval wall with the thinner 19th-century barn wall, but was keyed into the former. Thus, it appears that when the cross-wing was truncated prior to building the 19th century barn, the south end of its west wall was narrowed or built onto in tapering form before quoins were added, presumably to consolidate the structure. The southern barn appears then to have been abutted to the formalised south end of the medieval structure. In addition to work on the north and west walls of the West Range, excavation and recording was carried out prior to the demolition of a cross-wall and construction of the new end wall, while on the first floor above the vault the existing flagged floor was drawn and photographed prior to its removal and relaying.
