Eddison Manor
From Tardis Wiki, the free Doctor Who reference
Eddison Manor was the country house of Lady Eddison and Colonel Hugh Curbishley and was situated near Guildford, Surrey. Inside there was a library and a dining room, and surrounding the house was a park. (TV: The Unicorn and the Wasp)
Behind the scenes
Although the exact location of Eddison Manor is never explicitly stated onscreen, the Enquirer newspaper features a blink-and-you'll-miss-it article on the disappearance of Christie, which states that Silent Pool is located near Guildford, Surrey. As Eddison Manor is located only a short drive from Silent Pool, we can also conclude that it is also located near Guildford.
