There have been a number of alterations to Adam’s design for the front parlour. The columns are treated in porphyry scagliola, the oval ceiling and the chimneypiece all survive, but the columns have been repositioned and the large circular overmantel painting removed.
The overmantel originally displayed Angelica Kauffmann’s ‘Erminia’, but as Harris notes it was likely removed c1924, along with nine panels of stucco, when the room was redecorated for Lord Islington. Of the nine stucco panels, three of these incorporated oval mirrors designed for the space.
During a recent restoration the wall panels and mirrors were reproduced, faithfully recreating Adam’s original scheme.
