Until the early 1960s, it was largely based on the former English country house of Appley Towers (seat of the Hutt family, and later of Sir Hedworth Williamson) and neighbouring Appley Farm.
The family removed to County Durham as a consequence of marriage and from the 18th century the family seat was Whitburn Hall, near Sunderland ( the house was demolished in 1980).
