An excavation prompted by the redevelopment of 98a-100 Risbygate St identified features showing that the site was occupied prior to the construction of the existing timber framed building in the mid-late 17th century and the earlier occupation included some form of post built structure. The pottery suggests the site was in use from about the 12th century.
A clay floor was added to the timber framed building, possibly as early as the beginning of the 18th century, after the removal of a chimney stack and covered the site of the hearth suggested by an area of burning. The hearth demonstrates the level of the floor when the timber framed building was first erected and shows that the floor was originally just compacted earth. This lack of refinement suggests that this may have been an every day low status room, possibly a kitchen.
