Although none of the designs are dated, King dates them to c1786, which coincides with Adam’s commission for Delaval’s country villa Milburn in Esher, Surrey.

The scheme proposes a courtyard to the rear of the house, with a two-storey colonnade, and with a separate building containing kitchen offices, a dancing room and bedrooms. Adam volumes 33/97 and 33/96 show a stepped passageway from the kitchen offices to the basement level as providing access to the main house, along with the colonnaded walk which led directly into the ground floor Eating room. Adam volumes 35/98 and 35/95 detail how at first floor, the colonnaded link building provided access from the second drawing room into the dancing room beyond.
