- The drawings of Sir John Soane
The overall site is basically 180 feet from front to back and 28.8 feet wide. The length of the house including the 14 feet extension of 1802 (see, for example drawing  at ground floor level) is 88 feet. The length of the new offices at basement level (of 1818-19) is about 54 feet. The remaining area is forty feet long and into this was placed a stables 16 feet 1½ inches deep while the 'Standing for Three Carriages' with entrances and courtyard measured '23:0' by '33:9'. Added up (88 + 54 + 33:9) this comes to about 180 feet which suggests that the garden was entirely swallowed up? There might have been a paved garden of '28' 6"' wide and about 30 feet long over the basement extension (see drawing ) though this was overlooked by a two-storey kitchen and laundry.
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.
