Pitzhanger had already been structurally complete for two years when Soane, clearly not content with the arrangement - particularly regarding the Dance wing - made alterations to his earlier designs, as well as making some entirely new ones. In these, the Dance wing underwent dramatic cropping and was reduced to a bombé wing and is even removed in drawing 234 to form a completely symmetrical villa.

There are other smaller alterations in designs to 229 to 231: the addition of a staircase between the Library and Breakfast Room and slight alterations to the service wing. The final altered design for a double height conservatory (rather than the single storey version built) is particularly striking but was never executed.

Virginia Brilliant's TS Pitzhanger catalogue has been instrumental to the creation of this catalogue.
