Three features of archaeological interest were recorded during the evaluation comprising capping stones for a culvert, a further stone-lined culvert or drain and a wall. It is suggested that the culverts/drain may be associated with the medieval water system, perhaps as off-shoots from the substantial medieval stone-lined fresh water culvert identified during recent archaeological works along the eastern side of the former dairy (Green 2014). Both the culvert and the wall lie just below the proposed construction impacts for the areas within which they were identified. However, foundation trenches for a new extension would necessitate the removal of two short sections of the culvert/ drain, if indeed the feature is continuous given the heavy disturbance which was also evident. No finds were collected during the evaluation.
