This small room, called The Study in Adam's original design, has been used as a dressing room and a library. In 1958 it was converted into a cabinet room for the display of porcelain. The arched recesses in the east and south walls have been restored in accordance with Adam's drawings, with the difference that they hold china, not books.
The cabinets contain a wonderful collection of Sévres porcelain bought in the early years of the 19th century by Edward, Viscount Lascelles (1764-1814). A collection of Sévres includes pieces formally belonging to King Louis XV, King Louis XVI and Marie-Antoinette.
Joseph Rose executed the ceiling and the plaster roundels, one of which, is particularly engaging as it depicts a female centaur suckling her young. The relief over the chimneypiece is based on an ancient Roman painting of the first century AD known as the Aldobrandini Marriage, it shows a bridegroom waiting expectantly while his bride is made ready by female attendants.
