Notes
This drawing, SM 67/3/5 and SM 67/4/2 are for the structure of the timber roofs over Soane's side pavilions.
The drawing 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.
It 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 (SM 66/5/8) 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 the drawing corresponds to the section of roof over the pavilion is supported by the fact that it 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.
