This drawing combines a site plan with the garden (east) elevation of Sandycombe Lodge, Turner’s self-designed Twickenham house, more or less as built; it may date from 1812,1 when the building was probably under construction (see the overall introduction to the Sandycombe section). The sketch map below includes the approach to Richmond Bridge, east being at the foot of the sheet, and is not to scale, as the River Thames is proportionately much further away than indicated.
The verso (D40285) appears to comprise slight Sandycombe-related sketches.
See Youngblood 1982, pp.23, 28.
The sheet is trimmed straight at the left and at the bottom. The top edge is straight but torn rather than trimmed, and the right-hand edge is slightly irregular, such that the sheet is narrower by a few millimetres at the top. There are slight indications of a straight edge having been used on the verso to guide the tear.
