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 metres (1'4") below the present floor level. Loose material covering the full extent of this floor surface was removed, which exposed a compacted earth floor, which very likely would have once been covered in stone flagstones. Fortunately, the partial lower remains of the former 17th-century fireplace surround became exposed during these excavations, against the west wall along with the footprint of the former 17th-century fireplace opening and the remains of the hearth. These features are still preserved beneath the new floor in this room. Removal of the loose deposit overlying this 17th-century floor also revealed the lower section of two blocked in openings, one in the southwest corner of the room in the southern wall and another adjacent to this in the west wall alongside the former fireplace, the latter indicative of a possible doorway either leading to a former building to the west, now absent, or else a doorway to the outside. Another interpretation for this apparent opening may be that it is a blocked in alcove alongside the 17th-century fireplace. Because of the number of possibilities for this blocked in opening, this feature needs further investigation undertaken in the future in the form of excavation on the outside of the building to shed some light on its character.
