These designs appear inverted in relation to the present foliation of the sketchbook.
Turner’s built his self-designed villa at Twickenham, Sandycombe Lodge c.1812–13.1 Patrick Youngblood identifies these particular designs as transitional between two broad ideas that Turner considered for the plan, one thrusting out into the site, the other stretching along its contour.2 The most obvious drawing, bottom right, is perhaps the most complex idea that Turner evolved with its two wings each with large sideways-chamfered bays. The drawing to the left, as Youngblood observes, is close to the final design if one imagines it with the veranda removed. The fact, however, that Turner was still considering radical alternatives on this page suggests that he was still some way from finalising his plans to the extent that he could commence building. This is the last of the sketches in this orientation, that is entered against the numbered sequence. From the position of the bookseller’s label (see inside back cover and introductory notes) this sketch appears to belong to the first sequence of sketches made in the book and from its relation to the building of Sandycombe we might infer a date no later than the second or third quarter of 1812.
There are some splashes of ink offset from the drawing on folio 52 recto (D09129), opposite.
