1 The How, Hartsop, Patterdale with Hartsop, Cumbria. At the time the record was made The How, a small 17th-century vernacular house, required majorstructural repairs with the potential to destroy a range of historic features and evidence.The set of drawings represents the minimum necessary in this instance topresent the evidence on which the written report was based, and is typical of Level 3 records.
2 The Six Bells Public House, 9 High Street, Fulbourn, Cambridgeshire. Following a major fire a range of hitherto concealed elements of the timber frame wereexposed in the Six Bells Public House.The choice of drawings reflects the fact that the roof had already been destroyed in a previous fire and the ground floor,summarily recorded in a sketch plan of 1950, retained few historic features which could not be indicated satisfactorily on the sectional drawings.
3 (page 24) Oxburgh Hall, Oxborough, Norfolk: Section through Garderobes, from East. Like Drawing 4 this formed part of a large set of drawings, one group of which illustrated the complex arrangement of chimneys, garderobes, garderobe shafts and associated circulation within part of the gatehouse at Oxburgh Hall.Drawings of this type can elucidate particularly complex areas without recourse to full 3D CAD modelling. REDM survey was used to capture inaccessible detailon external elevations.
4(page 25) Oxburgh Hall,Oxborough, Norfolk: Plan of the Ground Floor. This plan forms part of an extensive set of drawings (see also Drawing 3) covering allthe main plan levels of Oxburgh Hall and sections at a series of key points.The drawings form part of a Level 4 record presenting a detailed investigation of the
building on behalf of its owners, the National Trust, with the purpose of underpinning long-term management.The plan is based on external, and highly selectiveinternal, REDM control; this was particularly necessary on the inaccessible moatside elevations.As well as recording a wealth of evidence (straight joints, blockings,variations in wall thickness and alignment etc) the plan clearly differentiates high- and low-status areas by indicating current variations in the decorative elaborationof rooms.
