AS Archaeology & Heritage Services was commissioned to provide a Desk Based Assessment (DBA) as part of pre-planning documentation for construction of a garden annex in the NW corner of Oakhill Cottage, Oakhill, Somerset (East Mendip near Bath and Bristol). Historical research indicated that the garden had probably remained largely undisturbed since the 19th century, although some made-ground terracing may have taken place in the intervening period. Archaeological potential was assessed as being Low to Moderate. A watching brief was advised.
