Survey drawings with rough design for a new house added, c. August 1800 (2)
Both drawings show a serpentine road enclosing the Pitzhanger grounds in which a symmetrical villa sits. The villa plan is very similar to the final designs for a villa at Acton, and they can probably be dated to a period slightly after, possibly even before Soane had finalised his purchase of Pitzhanger. Soane's hand can be seen in drawing 66 in particular, the brown ink and sketchy hand marking out the position of trees (even labelling one as 'Walnut') and lake next to the house.
