107 Baker Street

107 Baker Street was a house in London which the Fifth Doctor owned and lived in from November 1866 to November 1867. (AUDIO: The Haunting of Thomas Brewster)

Late in the First World War, Molly O'Sullivan stayed in Baker Street after leaving the front lines. The house had a secret cellar. (AUDIO: The White Room)

By 1970, the house was the base of the Ides Scientific Institute. In 1972, the Eighth Doctor visited Baker Street. Shortly after the Doctor arrived, a time-space portal opened and Daleks came through, chasing the Doctor, Molly O'Sullivan and Sally Armstrong from the property. (AUDIO: Fugitives)

From 2008 to 2010, Thomas Brewster lived in the house, which was given to him by the Doctor as a present. (AUDIO: A Perfect World, AUDIO: The Crimes of Thomas Brewster)
