Further investigations undertaken on the exposed standing fabric, following excavations in Sir Thomas Stepney's Study, have revealed that the east to west wall and the east wall of this room and very likely the eastern building as a whole, now occupied by the West Credit Union, post-date the cobbled surface and the slanted internal west wall, and given the recovered late-17th-century material from the overlying demolition deposit in this room, it would seem likely that this part of the house was most probably constructed in the early 17th century, perhaps post 1606/7, the time of the Great Flood, but certainly before the Civil War in 1642.
