Although this ceiling design makes use of neo-classical motifs, and is contained within the Adam drawings collection at Sir John Soane's Museum, it is highly uncharacteristic of Adam's oeuvre. According to Bolton it 'cannot be Adam'. It is possible that this design is by Stiff Leadbetter, the architect of Foley House, but it does not make use of his characteristic scale bar, and as such it is difficult to attribute authorship. It is not known if this design was executed.
