Historic building assessment by M Higgins of SCC of a high-status cross-wing (of 1425-50 date) to a medieval open hall that stood to the east.

Completion of watching brief begun in 2010 by N Randall of SCAU that revealed a series of broad ditches that may represent land boundaries pre-dating the construction of Pendell Court on the site in c1624, and finds of Mesolithic, Neolithic or Bronze Age, Iron Age, Roman, medieval and post-medieval date.

Watching brief by T Munnery of SCAU following evaluation in 2008 that had exposed the foundations of the church and three burials in the area of a proposed vestry. Parts of 60 inhumations and two cremations, all of Christian origin, and mostly thought to date from the previous 150 years were revealed, excavated and removed for later reburial elsewhere within the grounds of the church. Two pieces of pottery, dated to the medieval and Roman periods, were recovered from the subsoil and a grave fill respectively.

Watching brief by T Munnery of SCAU during gas pipe installation works. A post-medieval culvert of likely Victorian date was revealed, together with a small amount of medieval and post-medieval pottery.

Community archaeology project, Dig Preston 2011, undertaken as a collaboration by Preston Community Archaeology Project Group, Raven Housing Trust and SCAU. This located and uncovered sections of the manor house of Preston Hawe that stood on the site between the 12th and 15th centuries, and was previously investigated by Brian Hope-Taylor in the 1950s, and evidence of a chapel that served it.

Soil stripping, mapping and sampling of four large areas by A Thorne of ASE. Area one revealed a series of linear features and scattered pits and postholes, probably of Roman date and representing agricultural activity. Substantial evidence of post-medieval and modern field systems was also present in both above and below-ground forms. Areas two and three were badly truncated and damaged, but revealed similar evidence for agricultural land management and activity in the Late Iron Age/Early Roman periods. Area four revealed only a single post-medieval linear feature.

Evaluation by S Watson of PCA prior to use of the site as a possible extension to the existing burial ground. A likely Roman ditch and several undated, but possibly associated, postholes were revealed. Late medieval/early post-medieval pottery and ceramic building material were recovered from the subsoil, and a redeposited layer within one of the trenches is presumed to be associated with quarrying activity that map evidence illustrates took place just to the north of the trench.

Evaluation by S Wallis of TVAS at the rear of a property sometimes known as the William Mullins (one of the Pilgrim Fathers) house. The evaluation revealed a number of pits relating to domestic occupation of the site from the mid-12th century through to the 19th century. Some further work is proposed during the excavation of the service trenches, but a redesign of the proposed development to incorporate piling allows for the majority of deposits present to be preserved in situ.

Evaluation by H Rance of SLR revealed three ditches and the remains of an infilled pond. Environmental material sampled from the primary fill of the pond suggested a Saxo-Norman date for the deposit. Saxo-Norman pottery was also recovered from one of the ditches.

Two phases of archaeological excavations were undertaken within the Tilly's Lane development area on the north side of Staines High Street. A single trench was excavated at Tilly's Lane East between April and June 1999, with two trenches at Tilly's Lane West - British Gas and High Street sites - between February and May 2000. All the trenches lay on the gravel island, though Tilly's Lane East and the British Gas site lay within early flood zones.
