Small-scale excavation by D W Williams (following topsoil stripping of area just south-east of the Priory for construction of a children's play area) revealed evidence for a probable path founded on a great deal of building rubble perhaps taken from the Tudor mansion during alterations. The path is provisionally dated to the 17th or 18th century. (253; see also note in SyAC 81, 171))
Fieldwalking as a first stage of evaluation in advance of mineral extraction by S P Dyer for SCAU and Pioneer Aggregates UK Ltd. A number of clay pits were found across the area, presumably indicating clay was being dug for pottery manufacture. A quantity of Roman period pottery was found and it is known that this region had a widespread pottery industry from the 1st century AD onwards. However, a number of 16th and 17th century pot sherds, some apparently manufacturing wasters, were also found.
Fieldwalking in advance of construction of the golf course was carried out by P M G Jones of SCAU for O & J House Ltd. Some prehistoric flints were recovered, but the only evidence for occupation was two concentrations of building debris, which could be associated with buildings shown on a 17th century plan of the Pyrford estate.
A watching brief on groundworks at the Town Hall and some excavation was carried out by P M G Jones of SCAU for Spelthorne Borough Council. This confirmed that the building lay over medieval and Roman near-shore muds and silts which were sealed below 16th-17th century levels, probably representing foreshore reclamation. A reed peat filled feature of 15th century date was recorded, which contained numerous cut offs of wood and scraps of leather. The earliest buildings on the site appear to be late 15th or 16th century in date.
Observation by D W Williams of the digging of floodlight cable trenches south of the standing buildings revealed a number of general levels: featureless brown sandy loam below possibly 16th/l7th century layers below a possible 18th century courtyard surface, itself below a spread of late 19th century stone and brick rubble. At three points adjacent to the sunken garden were observed the substantial footings of stone walls bonded with yellow mortar.
Excavation by D W Williams of the surviving north-east corner of a 17th century building reconstructed in the 18th century. A section had been recorded in 1989; it had been discovered when a substantial part of the remains were removed for use as backfill for sand caverns. There was no evidence for earlier occupation along this part of London Road. Finds included part of a 16th century mullion and transom window, possibly from the Priory, and a complete late l7th century wine bottle, still corked and half full. (275)
A number of small 17th century and later finds recovered from beneath the floorboards by GMVEU. (282)
Several features identified by GMVEU during building works, including four pits and a ditch containing 12th to 13th century pottery; a mid-13th century well; a 17th century brick-lined kiln and other evidence for industrial activity; 18th and 19th century pits. (282)
Test excavations in advance of alteration and extension of the buildings, by Graham Hayman of SCAU for Triggs Turner Investment Co, recorded several pits and some walling of 17th-18th century date. Beneath these features, pits, postholes and stake holes of late 12th-early 13th century date were found. The majority of the pits had been used for domestic rubbish disposal. One very large feature is presumed to have been produced by quarrying for chalk. Levelling into the slope for building had truncated features towards the rear of the site.
A watching brief by A and D Graham on works within the standing Tudor building recorded a Bargate Stone lined well, dating to at least 1700, and a thin ashy layer containing 13th century coarse and white wares as well as fragments of ashlar masonry. These remains presumably relate to a medieval precursor to the existing building, known from documentary evidence. (294)
