 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.
