Excavation by R J Poulton for SCC, Hepworth Minerals & Chemicals and HBMC in advance of sand quarrying involved the stripping of almost lha. A scatter of mid Saxon pottery was found, but no features. cAD 1200 a hall house with circular tile-on-edge hearth and associated timber buildings was constructed. In the early 14th century the hall was replaced by a large stone-built structure with angle buttresses. This building continued to stand but a new hall with two-storied wings (one with a cellar) was built c1400, and linked to a square kitchen.

Excavation by P M G Jones for SCC, Prudential Property Services and Woolwich Building Society in advance of redevelopment examined aspects of the site from its street frontage to the Sweeps Ditch. There was some evidence for prehistoric activity in the area near the latter, at the northern end of the site. On the street frontage evidence for occupation in the 1st, 2nd, possibly the 4th, 13th, 14th and from the 16th to the 20th centuries was found.

Excavation by P M G Jones for SCC and Central Union Property Group revealed the rear of early-mid Flavian building evidence along the High Street edge. This was succeeded by a complex of buildings and refloorings at least to the late 2nd century. Buildings were apparently always of timber. There was evidence for flooding in the mid 2nd century. Other features included ovens, hearths, wells and pits. The site was covered by blackearth in the 4th century with some floor levels as yet undated. Saxon and medieval evidence

Excavation and site observation by P M G Jones for SCC and McKay Securities in advance of redevelopment examined a site at the confluence of the Thames and the Colne (as it existed from the late RB to the end of the Medieval period). Prehistoric peats and clays were found, cut by a late 1st or early 2nd century RB ditch containing leather offcuts and articles; any other RB levels must have been destroyed by later flood action .

Excavation by S P Dyer for SAFG in advance of redevelopment revealed a continuation of the multi period site at Petters Sports Field. Prehistoric worked flints, BA pottery, an IA terret (identified by the BM), a few sherds of probable IA pottery and mixed RB pottery were found in a buried river channel. The previously postulated RB road could not be located and the evidence suggested that it had not existed.

Excavation by G N Hayman for SCC and the City of London to test the area proposed for a sports hall produced confusing results. A probable RB chalk quarry and other features were recorded.

Evidence for the line of Stane Street (a continuous horizontal band of flints about 1.5m below the surface) noted by J Sankey in storm damage clearance. (230)

Discovery of 4th century RB coin in tree roots reported by Vivien Ettlinger.

Clearance after tree loss in 1987 storm observed by D J Field, D W Williams, D G Bird and others. No finds were noted but the conditions were difficult. Geophysical survey was later carried out by S P Dyer for SCC and HBMC and various anomalies were noted. This work was followed by the excavation of three trenches by R J Poulton to provide information on which site management decisions could be based. Two trenches on sloping ground produced nothing of interest; the third, on the top of the hill, revealed IA and RB pottery and features including an IA ditch running approximately east-west.
