Earthwork survey by L Gadsby of COT and K Page-Smith of Nexus recorded the surviving elements of the 19th and 20th century gardens. The presence of possible earlier remains associated with the woodland and rabbit warren formerly on the site was noted, including one possible pillow mound. An evaluation by T Harvard of COT recorded the footings of 19th century garden structures, but only the recovery of two pieces of unstratified worked flint suggested the possibility of earlier activity on the site.
