During excavations undertaken by Canterbury Archaeological Trust, ahead of the rebuilding of the Townwall Street filling Station, Dover, a complex series of stratified archaeological deposits were revealed representing activity at the site between the early Medieval period and later post medieval periods. Period 2, following the densely packed timber and stone buildings of the period 1 occupation of the site, there appears to have been a marked hiatus at the end of the 13th century, when the structures on most of the plots were abandoned.

Building 42, which was situated at the north western end of the site within plot B was not fully investigated, had it north-east end destroyed by later features and its south-east wall partially robbed to its foundation level. It consisted of substantial walls constructed from mortared greensand and flint which were supported on broad foundations of rammed chalk rubble and pebbles. The overall size of the structure was not ascertained but the minimum internal dimensions are 4.33m (NW - SE) and 8.06m (SW - NE). The substantial nature of the construction suggests an upper storey, and several phases of development indicate the use of this building over a considerable time. A garderobe shaft was inserted into the south-west end of the building. A layer of external flint cobbling was laid up to the outer walls later in the occupation of this building. (1)
