- The drawings from the office of Sir John Soane
The plans for the first and attic floors (drawings 4-5) are related. Both show six engaged columns in the centre of the front and a three-bay projection at the back. A central, rectangular, top-lit hall is placed at the rear of the building with an open-well staircase on one side and an enclosed servants' stair on the other. The first floor (bedroom) plan does not correspond with the one published in Soane's Plans, elevations and sections ... plate 13 but it does have some relationship with parts of the existing building, such as the 1724 building and the existing open well stair. A large domed room in the centre, rising through the attic floor, is intended for a chapel.
The suggestion is that these designs were made by William Heaton while he was clerk of works at Chillington (from 1 May 1786 to 27 October 1787) and represent two different schemes. Drawing 3 for an entirely new building, drawings 4 and 5 for a scheme retaining part of the old building. If this is the case, it is interesting that Heaton's drawings survived among those of Soane's office. See drawing 2 for another part-design and part-survey drawing attributed to Heaton.
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).
