The Morning Room was used by Merton as his study, despite the provision of a Study upstairs. He used an octagonal table that once belonged to Napoleon Bonaparte to work on.
The room was originally filled with paintings, ceramics and part of their Japanese collection. Portions of the ceiling came down in 1928 and is believed to remain underneath the present design. War damage to the building brought down the remainder of the ceiling, destroying much of the original decoration in the room. A new ceiling was designed and installed in 1949 by the artist, Anna Zinkheisen, (famous for her decorations for the luxury liner RMS Queen Mary and her design for a Quality Street tin).
