Ninety-five sheets, the earliest of which are Ordnance Survey maps from the edition of 1919, and a selection of general drawings from 1921. One ground level survey plan from 1921 appears in several copies, revised ultimately to 1980.
Also included are some general plans and sections from the 1970s, deed plans from 1973, site survey drawings from between 1979 and 1983, and a perspective sketch, probably from the 1970s or 1980s.
There are some photogrammetric survey drawings from the early 1980s, drawings from an archaeological survey made between 1993 and 1994, and consolidation drawings from 1994.
