BBC South East's Chrissie Reidy went for a tour of the historic home.
Eynsford Hill was built in 1913 by author Arthur Mee. His friendship with George Bernard Shaw led to Shaw naming the Eynsford Hill family, in Pygmalion after the property.
The property was constructed with no expense spared, after Arthur Mee had spent years searching for the perfect location to build a country house within striking distance of his office in Piccadilly.
The library is an exceptional room where Mee (1875-1943) wrote over 200 books, his most famous being the "Childrens Encyclopaedia" and "The King's England".
It also has some hidden secrets.
