Some properties will forever be woven into television history. The house on North Gower Street, London that doubles for Mrs Hudson's house at 221b Baker Street, where Sherlock Holmes and Dr John Watson lived in the BBC Cymru Wales series Sherlock is instantly recognisable.
The huge and magnificent mansion where Downton Abbey was set, Highclere in Berkshire, is etched into every viewer's memory and, at the other end of the size scale, the Peckham tower block where Del Boy and Rodney Trotter lived is now a legendary address.
Closer to home in Wales, the Barry terrace house in Trinity Street is quickly remembered by Gavin & Stacey fans. And just around a few corners in the same town is 'Honolulu Heights' on Canon Street, where a vampire, werewolf and ghost lived in the cult classic supernatural drama Being Human starring Aidan Turner, that is a favourite with fans.
