Conservation Area has been extended and redesignated. The Conservation Area is centred on Bridge Street, South Street, High Street, Higher Street, Victoria Road, Market Street, Park Road and Oakfield Road. At its southernmost point it encompasses the bridge over the River Lew, the Hatherleigh County Primary School and Reed House, before running north, beyond Coombe into Higher Street. It skirts the west side of Normandy Place, into Victoria Road, then runs west and northwards around Biddlecombe. Travelling north westwards, the boundary encompasses the orchards and pastures which form the setting to Montague House.
The boundary then crosses Red Lane to Sanctuary Lane, taking in the grounds of Hatherleigh Place. It extends northwards to include Oslo and the Vicarage, before turning southwards between the properties in Bridge Street and the cattle market, until it reaches the River Lew. Before 1974 the designation comprised two areas, one centred on High Street and the other on Market Square.
