These three drawings are for the structure of the timber roofs over Soane's side pavilions. Drawing 205 shows a truss girder and king post with an additional truss and king post directly over the first, secured in place by a long screw.

The section (drawing 205) corresponds to the roofs over Soane's pavilions: the plan National Archive (PRO) Works 31/220 shows the internal walls here to be much thinner than those in the central body of the Secretary's Offices. Indeed, the pavilions' southern-most internal walls are no more than partition walls. Moreover, the elevation (drawing 211) shows that the external wall is more window than wall. As a result, the weight of the roof over the pavilions would require extra support, given by a double arrangement of king-posts and a 'Truss Girder which serves in the Place of a Wall'.

That drawing 205 corresponds to the section of roof over the pavilion is supported by the fact that the drawing shows a downward slope of the roof meeting an upright chimney flue (on the right hand side of the drawing), which corresponds to the arrangement of roof and chimney stack on the built pavilions.

The roof sections of drawings 206 and 207 show the lower of the two trusses and king-posts of drawing 205. Drawing 206 also shows a detail of the rubbed brick pavilion window surround and a detail of a brick arch, which presumably was internal to the pavilion. The centering wedges are shown, which would have been knocked out to let the arch fall correctly into place. Drawing 207 shows a section through the internal height of the pavilion, including the internal arch shown in drawing 208.

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).
