Two of the preliminary designs for the ballroom and concert hall (Adam volumes 1/1 and 1/3) have previously been alternatively attributed by Alan Tait as being for unexecuted assembly rooms in Edinburgh, and therefore dating from the Adam brothers’ Scottish office before they went on their Grand Tours. It is argued here, however, that the density of Roman motifs within the schemes were both informed and influenced by the Adam brothers’ Grand Tours. Moreover, the similarity between these drawings and the Adams' others for the rooms (Adam volumes 21/61, 27/54, 27/51 and 28/48) is too striking to be ignored.

It must be noted that one of these drawings (Adam volume 1/3) is inscribed in pencil with Sketch of a Project for Edinr, but the hand of this inscription is not known, and may have been added later and/or misinscribed.

The Adam brothers’ designs for the Bath Assembly Rooms were not executed. See scheme notes.
