The building was rewired, the plumbing and heating were overhauled, and six self-contained staff flats created to replace the small staff bedrooms and communal servants' hall. Including those in the staff flats, 17 bathrooms were added to the existing handful. The 6th Duke's cavernous kitchen was abandoned and a new one was created closer to the family dining room.
