An archaeological watching brief was carried out during the groundworks for a new extension at Old Tiles Cottage, Church Lane, Hellingly, East Sussex. Excavation of the footing trenches for the extension and a new northern boundary wall were monitored. No archaeological features were encountered and only a small assemblage of finds was recovered during the watching brief. The earliest finds dated to the mid 18th century. No evidence for earlier archaeological activity was found. It appears likely that the construction of Old Tiles Cottage in the 20th century created layers of made ground, and may have removed any evidence for earlier activity that existed on the site.
