Appraisal by M Higgins of SCC of an urban building within a tight plot. It was brick fronted with a studwork rear elevation over a brick ground floor. The building is of two storeys with a stone cellar and attics in a staggered butt-purlin, butt-rafter roof. The exterior has a fine Flemish Bond facade with blue headers. Number 42 has cruciform windows in the original openings; 44 has been remodelled but straight joints reveal its original format. Each has an end chimney stack and both date to the early 18th century over a probably earlier cellar.

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.
