 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.The room known as the Great Hall, which formerly occupied the north-western part of the ground floor, has suffered inexorably over the years, especially from the insertion of shop-fronts in the mid- to late 19th century, which unfortunately destroyed all of the north and west facing elevations at ground level and also removed much of the former timbered floor having been destroyed and replaced by concrete in the 20th century.Following the removal of the concrete floor, excavations in the Great Hall for the insertion of a proposed new floor exposed the surface of the 17th-century floor, lying approximately 0.40 m below the present floor level.
