Walter Payne, clerk of works


Walter Payne served as clerk of works at the Bank of England from 1789-1833, as well as acting for Soane in a private capacity at Pitzhanger Manor. His drawing is for one of the trusses supporting the roof of the Royal Entrance. A collar beam is a 'horizontal member spanning a pair of principal or common rafters between apex and wall-plate' (J. Lever and J. Harris, Illustrated Dictionary of Architecture 800-1914, 1993).

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.
