The interior of this room is a tour-de-force designed, made, and supplied by Thomas Chippendale the Younger in 1789-91. Chippendale advised Ninian and his wife on decorating the ceiling in colours and undertook all the decorative carving around the room. Chippendale supplied and hung the wallpaper and large pier glasses which came from Paris. The firm made the two sofas, all the chairs, the tea tables, and the set of three pier tables which were made to exactly fit the spaces between the windows.
