Magnetometer Survey by D Sabin of Archaeological Surveys Ltd revealed evidence of former field boundaries, together with some evidence of former agricultural activity, possibly ridge and furrow, and a number of anomalies that it was not possible to confidently interpret.

Geophysical survey by S Haddrell of Stratascan along the 28km route of a proposed replacement pipeline between Godstone and Tonbridge in Kent. Magnetic susceptibility was undertaken along the route, with areas of potential interest identified targeted with a detailed gradiometer survey. Positive anomalies, possibly of archaeological origin, within the Surrey section included linear features that may be associated with a post-medieval trackway. The anomalies were targeted during a subsequent evaluation by D Britchfield of WA.

Evaluation by N Randall of SCAU revealed a large tree throw hole containing Mesolithic flint, a substantial prehistoric ditch, Bronze Age and Iron Age gullies, a large medieval pit and a post-medieval stone capped culvert. The evaluation illustrated that archaeological deposits lie at a depth that will not be impacted on by the majority of groundworks involved in the development proposal, and they will be preserved in situ underneath it. Those parts of the site where the development had the potential to impact on deposits were subject to a watching brief by N Randall.

Evaluation by C Turner of HN revealed evidence of extensive modern terracing but no finds or features of archaeological interest.

First phase of the evaluation of this site by Z Pozorski of AS revealed a pit and ditch. Although it may be residual, a fragment of Neolithic or Bronze Age struck flint was recovered from the pit. A subsequent monitoring exercise during development did not reveal any further archaeological finds or features. A second phase of evaluation revealed an undated ditch.

Programme of fieldwalking by S Ford of TVAS recovered a dense cluster of struck flint located on the terrace edge of a small stream valley. The cluster comprises a strong Mesolithic component, although later Neolithic/Bronze Age material is well represented. Flint in more modest quantities and pottery sherds of several periods were also recovered dispersed elsewhere across the areas fieldwalked.

Evaluation by D Hopkinson of ASE revealed the remains of a mid 19th century farmstead building, possibly an open sided barn, and a number of pits likely to be for refuse disposal from a similar period. The building had been built over an earlier infilled sandstone quarry cut. Residual pottery and ceramic building material of medieval date recovered from the topsoil and subsoil suggest that there may have been some activity on the site prior to the 19th century, although it is more likely that the ceramics were brought on to the site during manuring.

Excavation (1976) by Mary Saaler for the Bourne Society and the SyAS revealed no obvious explanation of a mark located on aerial photographs, and no ancient material. (135)

Excavation (1975-6) by Lesley Ketteringham for the Bourne Society recovered the plan of a large barn probably demolished c1262. A dump of several hundred decorated floor tiles of 16 different designs of 'Westminster' type, probably originally coming from the ancient manor house (demolished early 17th century), was found in the remains of a small outbuilding.
