Cultural significance: The house links two prominent storytellers—an Oscar-winning actor famed for roles such as Pip in Great Expectations and the author behind the Mr Men series.

# What this house is

# Why the house matters

The house has been a private home for two figures with public profiles in 20th-century British culture. In the 1950s and 1960s it was the family home of Sir John Mills, an actor whose career spanned before and after the Second World War and who won an Academy Award for his role in Ryan's Daughter (1970). Decades later the house was owned by Roger Hargreaves, the advertising copywriter who created the Mr Men series and wrote the Little Miss books while living at Sussex House Farm.

# Sir John Mills and the house

Mills lived at Sussex House Farm during the 1950s and 1960s. His screen career includes In Which We Serve (1942), This Happy Breed, the role of Pip in David Lean's 1946 Great Expectations, and the beer-drinking scene in Ice Cold in Alex. Mills later moved to Denham with his second wife, Hayley Bell, where they lived until his death in 2005 at age 97.

The proximity to Kent Water and to villages such as Cowden and towns like Sevenoaks positions the house for country living with relatively easy access to local centres.
