Appraisal by M Higgins of SCC to inform Listed Building Consent proposals. Constructed in three main phases, the first phase is a 2½ bay, timber-framed, end smoke-bay house of suggested late 16th century date. A large timber-framed bay with a chimney was added to the south end in the late 17th century, possibly with an outshot on the west side. A third, 18th century phase saw a face wing with outshot added to the south-west possibly with masonry on the ground floor under a timber-framed first floor replacing the outshot of the previous phase.

Archaeological monitoring by N Randall of SCC during groundworks for a small extension. Excavations revealed extensive disturbance from modern services and the presence of a large, modern subterranean cistern but no finds or features of archaeological interest.

Evaluation by L Newton of WA revealed no finds or features of archaeological interest. Two wheel ruts and an area of disturbance were deemed to be of modern date.

Two phases of archaeological evaluation by J Clutterbuck of COT. No finds, features or deposits of archaeological significance were found pre-dating the modern era. Some linear features were identified, likely to be modern ditches associated with military training activities.

Second phase of evaluation, by H Nicholls and J Cook of ASE following an initial evaluation in 2015 (SyAC 100, 287). No archaeological finds or features were revealed as a sequence of contaminated modern made-ground deposits, directly overlying truncated natural geology, was present across this area of the site.

Watching brief by W Weller and M Saywood of SCAU during ground level reductions for the installation of an anaerobic digestion facility revealed that the area was deeply disturbed, with made-ground comprising large amounts of 20th century waste. No finds or features of archaeological interest were revealed.

Evaluation and excavation by M Edmunds, A Haslam and P Jorgenson of PCA carried out prior to and following the demolition of the former shops and residences fronting the High Street (Historic Building Recording: SyAC 101, 222). Staines-upon-Thames is located above a series of low-lying gravel islands within the flood plain of the middle Thames valley, on the north bank of the river Thames at its confluence with the braided tributary channels of the rivers Colne and Wraysbury.

Watching Brief by M Saywood of SCAU revealed no archaeological features or finds pre-dating the 19th century.

Strip, map and record excavation by W Weller of SCAU revealed a significantly disturbed area with three ditch features and a small posthole, all of which have been confidently dated to the later post-medieval period. A handful of probable Bronze Age flints was recovered, but no features of this date were observed. The small posthole from the trial trench evaluation (SyAC 101, 221) that produced a small assemblage of prehistoric pottery was located, but no further related features were observed.

Strip, map and record excavation by W Weller of SCAU, a continuation of the 2016 excavations (SyAC 101, 220), revealed further significant archaeological deposits. The most notable being the Roman road, the roadside ditch of which was previously excavated. Large elements of the road surface were intact, and a camber was visible in section, together with distinct layering relating to re-metalling. A section of ditch was uncovered that contained two sherds of Late Bronze Age pottery that probably date the feature.
