The complete removal of the floor-boarding in Sir Thomas Stepney's Study revealed that there was in fact two parallel north to south aligned cross walls, partitioned by a further east to west cross wall. Each of the tops of the walls was surmounted by wooden planks, which were themselves supporting the existing oak floor joists. Groundwork for a series of three proposed north-south floor support channels, through the deep demolition deposit below the existing floor, exposed the remains of another stone pitched or cobbled floor surface, which appeared to cover almost the entire area of the room. At the far southern end of this room further excavation revealed that the short partition wall, which divided the two stone cross walls, was in fact the remains of a low basement area, which appeared to have been retained when the floor level had been raised in this room. Former access to this low basement or storage room appears to have been gained through an opening at the far south-western corner of the room via a flight of stone steps also exposed during excavations. Dateable material recovered from the apparent deep demolition deposit from this room included three clay pipe tobacco bowls, each dateable to between 1660 and 1680, several large fragments of 17th-century decorative plasterwork and an almost completely intact tall necked octagonal green glass wine bottle dated to between 1660 and 1700.
