Auderly House

Auderly House was a large white Edwardian Manor House around fifty miles north of London, owned by the British government. In the late 20th century, a World Peace Conference was going to be held there, led by Sir Reginald Styles. (TV: Day of the Daleks)

The Third Doctor and Jo Grant were sent to Auderly House by UNIT to investigate 'ghosts'. The house was destroyed by time-travelling guerrillas, mistaken for ghosts, from an alternate 22nd century to prevent the Daleks from altering history. (TV: Day of the Daleks) Ace appeared in the house to seek a missing segment of the Key to Time, which was in the form of a rapier wielded by the Doctor against her. (COMIC: Time & Time Again) The reporter James Stevens infiltrated the mansion grounds later and witnessed a battle between UNIT troops and Ogrons, the servants of the Daleks from the alternative future. (PROSE: Who Killed Kennedy)

After the evacuation of the mansion, Shura, one of the guerrillas from the future, gave his life to detonate a dalekanium bomb in the mansion's cellar, killing the Daleks and Ogrons sent to the 20th century. (TV: Day of the Daleks)

Alternate timeline
In the alternative future, Shura had destroyed the mansion with the peace delegates still inside. The resulting international crisis had caused the warfare which, raging across Earth, left the planet vulnerable enough for the Daleks to have invaded without resistance. (TV: Day of the Daleks)
