This set of highly-finished drawings, drawn by Robert Smirke in the late summer of 1796, was probably done for Soane's own pleasure and as a record of his first major work at the Bank. The drawings were neither exhibited at the Royal Academy nor presented at the Bank, as far as is known. They may perhaps have been made as a response on Soane's part to the criticism his unorthodox decorative style was beginning to receive at this time (A. T. Bolton, The Portrait of Sir John Soane R. A., 1927, pp. 59-79)

The reflected-ceiling plan shows the simple arrangment of the piers and responds. But the main focus is on the hall's nine separate vaults (made up of four distinct types), whose composition and decoration represented the crux of Soane's achievement at the Bank Stock Office.

The views looking north and east are theatrically framed by the overhead vaulting and emphasise the hall's top-lighting and the contrast between areas of light and shade, what Soane called the 'poetry of architecture'. Besides the hall's architecture, the counters, central stove, and north wall chimney piece are also depicted.
