The back drawing room was the back room on the first storey.

This design for the ceiling of the back drawing room is an imitation of a painted vault in the Palace of Augustus, on the Palatine in Rome. It was not executed. Instead, Adam's design for the back parlour - the corresponding room on the floor below - (Adam volume 12/5) was installed in this room and remains in situ. The only element of the ceiling which does not survive are the medallions which were painted by Antonio Zucchi.
