the office of Messrs Thellusson, Nephew & Co.


post horn within crowned cartouche and below, 1808


The firm of Messrs Thellusson, Nephew & Co. occupied house No. 2 in the new bank buildings after relinquishing their reservation of No. 3. Soane had previously made designs and alterations for three members of the Thellusson family; for Peter Isaac at 15 Philpot Lane (1792), for Charles in Fenchurch Street (1792) and for George Woodford at Wall Hall, Hertfordshire (1800, unexecuted). All three were sons of Peter Thellusson (1737-97), an Anglo-French banker and businessman who served as a director of the Bank of England (as did Peter Isaac). It was George who, in partnership with his nephew, also George, and William Mitchell moved the firm into the new premises in Princes Street.

This design, received by Soane on 14 February 1810, shows Thellusson's proposal for extending the rear of No. 2 to create a new counting house. Soane's original design (drawing 67), however, was executed.

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).
