Notes

This drawing and SM volume 74/134 show the designs for the later south Transfer Office foundations, during or after the demolition of the internal hall structure. The plan must show the later south Transfer Office because of the irregular longitudinal wall-line (very similar to SM volume 60/30). The drawing shows the lines of force acting on the foundation arches and its late date similarly indicates that it is the later south Transfer Office.

As noted for SM volume 71/44a and SM volume 71/35, inverted foundation arches were an inexpensive method of providing strong foundations where a great weight was to be placed above. The more expensive method involved driving piles deep into the ground and it would have been impractical for Soane to alter the method of construction. Inverted arches counteracted the forces acting on them from above, carrying the strain inwards to the centre, rather than directly down through the pier to the foundation base. The key stone of the inverted arch acts in exactly the same way as a normal arch, taking the pressure.

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.
