The proposal here is to extend the back part of the house by about 17 feet. This would alllow for an extra bedroom on the first floor measuring 28:6 by 16:0 feet. On the ground floor the extant library was to be moved forwards into the garden which would permit (in the middle of the house) the addition of a water closet and the enlargement of the ante room between the entrance hall and library. From the specification (see drawing [8]) it seems this idea was not carried out. The Survey of London, volume XL, p.162 describes the proposed new library 'as completely recast .... The eastern wall was curved, and although the old fittings were removed they were echoed in the repeated round-headed mostifs of Soane's finely judged wall designs, where they were delicately juxtaposed to segmental and rectangular forms, and created an effect reminiscent of a Roman catacomb.'

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).
