Evaluation and subsequent excavation by R Taylor-Wilson of PCA, for Crest Homes, of this redevelopment site adjacent to the Thames. Struck flints recovered indicate Later Neolithic and Bronze Age settlement in the near vicinity, with some indication of Later Mesolithic or Early Neolithic activity as well. The site was most extensively occupied in the Later Iron Age, when a settlement, probably a small farmstead, was established, the main focus of which was outside the excavated area. The main features excavated were a series of enclosure ditches and numerous pits and postholes.

Evaluation by A Gollop of PCA of a site proposed for residential development, for Crest Homes, revealed a ploughsoil below modern makeup levels. The ploughsoil contained a couple of sherds of medieval pottery and may represent agricultural activity on the site from the medieval period onwards. No earlier archaeological features or finds were revealed.

Evaluation by P Moore and M Bagwell of PCA, for BP International Limited, and a subsequent watching brief, revealed that much of the site had been truncated by previous building work. Two trenches did reveal intact upper soil horizons, but no archaeological features; the discovery of a residual flint flake, probably of Mesolithic or early Neolithic date, was the only indication of activity of any antiquity.

Evaluation by D Dobson and D Killock of PCA, for Crest Homes, revealed evidence dating from the post-medieval period to the present day. One trench produced Bronze Age flintwork and a late 12th century pit. Further work revealed a truncated ditch aligned roughly east to west, the fills of which contained a sherd of Mid-Late Saxon pottery and one dating to the 12th century. This feature is likely to be the remains of a field or enclosure boundary.

Evaluation by S Farid of PCA, for Laing Homes Ltd, in advance of redevelopment. Apart from modern drainage features, no archaeological deposits or features were identified.

Evaluation by D Divers of PCA, on behalf of Barratt Southern Counties, on part of the former hospital’s grounds in advance of residential redevelopment. In one area of the site, the natural was found to have been truncated by terracing. Some finds of interest were recovered; a flint blade and waste flake, two abraded sherds of 1st century Roman pottery, and several fragments of medieval roof tile, but no features were revealed.

Evaluation by D Divers of PCA, for Laing Homes South Thames, in advance of residential development of a site on the projected route of the branch road from Stane Street to the Ashtead villa. The trench revealed modern deposits overlying the London Clay and no features or finds of archaeological interest.

Evaluation by G Brown of PCA, for Barratt Southern Counties, in advance of residential development, revealed only a linear feature containing brick fragments of post-medieval date.

Observation by R Young of PCA of geotechnical survey, to clarify the level of truncation across the site. The survey suggested minimal truncation between the existing buildings on the site, and the nature of the deposits indicate a complex history of flooding and reworking of deposits by alluvial action. Possible archaeological deposits containing burnt flints and clay were observed in two boreholes.

Watching brief by K Sabel of PCA on geotechnical trial pits. Evidence for the 17th-18th century origins of the building were revealed, including earlier foundations, drainage and timber flooring. Remains pre-dating Waterloo House were also revealed, in the form of surviving post-medieval layers and residual medieval building material. Considerable evidence of Saxon/Early Medieval occupation was recovered also.
