This is one of numerous pages in this sketchbook relating to Turner’s self-designed Twickenham house, Sandycombe Lodge (see the Introduction to the sketchbook). As noted under D08966 (CXXVII 2), most of the designs in the book show variations on the central block of the house more or less as built, with variations in the lower flanking wings.1
See Youngblood 1982, pp.29, and 35 notes 78–82; see also Warrell and Perkins 1988, p.24.
This page is a face of one of the loose bifolio sheets which form the majority of the so-called Sandycombe and Yorkshire sketchbook, along with a few single leaves. The sheets were not bound, but folded inside each other in a sequence which is not entirely recoverable (see the sketchbook’s Introduction for a suggested order). When unfolded, this page is continuous with the verso of D08986 (CXXVII 16); the measurements given above are for the present work alone.
