The Scala Regia rises 8' 10½'' over a distance of approximately 25 feet and consists of three sets of seven stairs with a total length of 33¼ feet. The two openings to the right hand side give access to the area underneath the top flight of stairs. The inverted arches are part of the foundations. Soane was forced to change the design of the foundations after discovering a mistake in the surveys made by his pupils (see also SM 71/2/44 and SM 71/2/50v).

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).
