SM Adam volume 28/56
 Finished drawing for the garden (south) front of the house, executed with alterations, 1771
Adam office draughtsman, possibly Joseph Bonomi, and title inscription in the hand of William Adam. Bolton suggests that the draughtsmanship of this drawing is by Giovanni Batista Borra, presumably as Borra had been responsible for the previous south front of the house. This is incorrect as it is unlike Borra's hand and he died in 1770, one year before the drawing was made.
