Soane's survey drawing (4) shows part of the first floor above the kitchens before alteration. Downing Street is to the left of the drawing. A note in Soane's hand at the bottom of the page refers to the outcome of a meeting on Sunday 3 July when Soane 'attended the Ch. of the Exchequer [with] 2 fair plans & two perspective views of the new eating room & anti room (sic) proposed to be made in his house' (Day Books, 2 July 1825).

The water closet shown in drawing 5 was significant to Soane's design for the State Dining Room as it played a part in defining the final shape of the room (P. Dean, Sir John Soane and London, 2006, p. 114).

Sir John Soane's collection includes some 30,000 architectural, design and topographical drawings which is a very important resource for scholars worldwide. His was the first architect’s collection to attempt to preserve the best in design for the architectural profession in the future, and it did so by assembling as exemplars surviving drawings by great Renaissance masters and by the leading architects in Britain in the 17th and 18th centuries and his near contemporaries such as Sir William Chambers, Robert Adam and George Dance the Younger. These drawings sit side by side with 9,000 drawings in Soane’s own hand or those of the pupils in his office, covering his early work as a student, his time in Italy and the drawings produced in the course of his architectural practice from 1780 until the 1830s.

Browse (via the vertical menu to the left) and search results for Drawings include a mixture of Concise catalogue records – drawn from an outline list of the collection – and fuller records where drawings have been catalogued in more detail (an ongoing process).
