Further excavation by the Roman Studies Group of SyAS, directed by E Corke and D Bird to the north-east of the Scheduled Roman villa, recorded considerable quantities of unstratified Mesolithic and Neolithic struck flint from across the site. A possible Bronze Age barrow ditch and two adjacent pits, again of probable Bronze Age date and thought to represent inhumations where no bone has survived, were also revealed. Iron Age features in the form of a curvilinear enclosure ditch and a number of pits were recorded.

Evaluation by D Milbank of TVAS revealed a single linear feature that contained a small quantity of pottery of Late Bronze Age or Early Iron Age date and a small assemblage of struck flints.

Evaluation by T Collie of SCAU. The results show prehistoric and/or medieval or early post-medieval activity across the area. Most of the features were identified in trenches located across the western half of the southern field, and they include a number of substantial ditches of probable medieval or early post-medieval date.

Evaluation by W Weller of SCAU revealed no archaeological features. Some finds were recovered from the subsoil and spoil heaps including a small amount of struck flint and post-medieval/modern ceramics.

Watching brief by W Weller of SCAU showed the site to have been severely disturbed. However, a large ditch of probable Roman date was observed close to the main school building and is possibly a continuation of ditches excavated by S S Frere in 1939 and 1940 (SyAC 48, 45–60). A compacted chalk layer, which may represent a courtyard area between buildings noted on the Ewell Enclosure Map of 1803, was also recorded. A quantity of worked flint of Mesolithic, Neolithic and later Bronze Age date was recovered, indicating activity during these periods within the vicinity.

Evaluation by C Russell of ASE revealed two linear boundary features of probable medieval date and finds that suggest domestic activity of a similar date in the vicinity. The recovery of a small assemblage of prehistoric flints suggests activity from the period on or near the site.

Watching brief and subsequent detailed archaeological excavation by G Santamaria of WA to the north and east of previous phases of work (figs 6 and 7) and an exploratory machine slot excavated through a possible palaeochannel revealed but not investigated during the 2015 season. The possible palaeochannel measured c 40m in width but was relatively shallow, at a maximum of 2m to the underlying sand (fig 8).

Excavations by J Payne of SCAU ahead of planned mineral extraction revealed evidence of archaeological activity dating from the Mesolithic through to the post-medieval period. The more important finds included a pit that contained Beaker-type ceramics, diagnostic flint tools of Neolithic and Early Bronze Age date and the remnants of a Middle/Late Bronze Age field system, which was in part truncated by a Middle/Late Iron Age settlement. The Iron Age settlement comprised a series of ring-ditches and numerous discrete cut features set within a substantial enclosure ditch.

Evaluation by K Marshall of PCA revealed two linear features, one of which contained a single degraded sherd of pottery dating to the later prehistoric period.
