Drawings 264 to 266 all show the ruins at Pitzhanger. Drawing 264, although it is dated to 1810, is still a retrospective view and dates to the period after Soane's ownership of the house. It is therefore included with the 1830s drawings on the same subject.

Drawing 266 shows a sarcophagus-like object, surmounting the triumphal arch structure, with tall finials at each corner, with canopy dome caps. It seems as if Soane was trying to suggest that the ruins were a source for, or even an integrated part of the architectural vocabulary for the rest of the house.
