The Carlton Room on the ground floor used to be the smoking room of the United Service Club. It is adorned with many rich decorative features including the dramatic Ionic columns in the centre of the room. These are finished in scagliola; a skillful plaster treatment designed to imitate marble and add to the splendour in the room. The walls are also covered by gold leaf on linen; a very expensive and delicate treatment enriching the overall impression of opulence.
The south facing doors open onto a private terrace with views across the garden.
