Wessex Archaeology was commissioned by Arup, to undertake an archaeological evaluation of a 4.34 ha parcel of land located at Northfield, Land off Leigh Close, Row Town, Surrey, centred on NGR 503856 163187. Following consultation with the Surrey County Council Archaeological Officer, the trial trench evaluation was deemed necessary in order to better understand the surviving archaeological footprint across the site. A total of 22 trenches were excavated. Originally proposed as 50 m long several were moving and/or shortening due to the presence of onsite constraints such as field boundaries and trees. The soil sequence was found to comprise topsoil, overlying a subsoil which in turn overlay the geology. Slight variations within the geology were noted with sand noted in the majority of trenches, and patches of clay and sandy clay also recorded. Significant archaeological features, likely associated with a funerary site identified immediately to the east were uncovered. An Iron Age ring ditch and associated postholes indicate a roundhouse or similar structure and Romano-British ditches likely represent small, localised enclosures. A Romano-British pit may also represent further funerary activity. Networks of undated ditches were also revealed and are believed to be associated with agricultural activity dating to the post-medieval period. A modern field boundary was also located. There were significant archaeological remains across the site, with a particular concentration in the south, where a ring ditch contained pottery dating to the mid-late Iron Age. The ring ditch was close to a number of postholes. It is believed that the ring ditch and postholes form part of a roundhouse associated with a cremation cemetery immediately adjacent to the site, which has been subject to archaeological excavation. A pit revealed in Trench 9 containing a particularly dark deposit with charcoal and pottery, may represent further funerary activity. There was also a network of field boundaries/drainage ditches, which were also identified by a geophysical survey undertaken prior to the evaluation. Though the majority were undated, a postmedieval field boundary depicted on early Ordnance Survey maps and, identifiable in the geophysical survey results, traversed the site. A number of these ditches were dated to Romano- British period and, were believed to represent small enclosures, indicating a further phase of occupation into the Romano-British period.
