An archaeological watching brief was maintained during the groundworks associated with the construction of a single storey rear/side extension at 30 Western Road, Lewes, East Sussex. The excavation for the footings and ground reduction was carried out by hand. Part of a medieval feature, probably a 13th century pit, was encountered in the westernmost footing during the watching brief, with the remainder of the feature lying outside the area of excavation and under the floor of the old kitchen
