 A boarded ceiling with deep cornices and high level windows is located in the rear northeast room, which is the location of the maid's dining room and scullery prior to the building's conversion into flats.The rear room (within the lean-to) has boarded walls and raked ceiling, and was used as a work room at the rear of the museum prior to the conversion into flats.A lightwell has been inserted into the eastern side of the "museum" wing adjacent to the early section of the structure (in place of the original openings into the museum from the former dining room and courtyard), and provides light and ventilation to internal rooms adjacent.
