Ten trenches were opened mechanically under archaeological supervision and potential archaeological features investigated by hand. The evaluation was successfully carried out and identified archaeological deposits of prehistoric and Saxon date across much of the site, despite earlier development having truncated parts of the site. The prehistoric deposits may indicate settlement activity on the site, as the three postholes identified in trench 6 could be from a postbuilt roundhouse. The later Saxon deposits likely relate to the Middle Saxon settlement activity identified immediately to the south-east and may indicate higher areas of occupation close to the wetter areas nearer the River Thames.
