machine excavation was used to define carefully the extent of any surviving structures, features, and other remains. This was carried out using a mechanical excavator of appropriate size and power under the supervision of an experienced archaeologist. Thereafter, the remains were cleaned manually to define their extent, nature, form and, where possible, date. Once the extent of buried archaeological remains was established they were subjected to detailed archaeological excavation and recording. Hand excavation was undertaken by trained professional archaeologists. The earliest phase represented worker's housing constructed in the late 18th or early 19th century. Five of the houses incorporated cellars which were largely intact and featured staircases, fireplaces, floor surfaces and other internal fittings. In total at least 14 internal cellar rooms were identified plus three external privies. The presence of fireplaces within eight of the cellar rooms, plus lightwells and dedicated stairways providing access to surrounding streets, suggests that the cellars were initially used as dwellings. The second phase of development represented alterations to the cellars, which appear to have been implemented in the mid- to late 19th century, such as the blocking of doorways and the installation of drainage systems. It is inferred that the function of the cellars may have been modified from living spaces into utility or storage areas. Finally, the piecemeal demolition of buildings covering the site reflects slum clearance directives instigated from the early 20th century
