An archaeological watching brief was carried out at New Cottage, Winchelsea, East Sussex following a previous evaluation excavation prior to ground work for the construction of a single storey rear extension. Excavation of footing trenches revealed a rough-hewn mortared stone feature and a layer of mortar was similar to one found in the original evaluation excavation. These features extended beyond the excavated trenches, but both features were recorded prior to pouring of concrete footings. Trenches close to the existing house showed signs of back fill from the house construction with building debris. Further away less disturbance and debris was evident.
