16 Candleford Street

In 2009, Roger Davey lived alone on 16 Candleford Street, which was in Haringey, London. When he bought the house, there was a cat flap in the front door, though he never owned a cat. After he began taking Adipose pills, the house's burglar alarm went off every night at ten minutes past one, when an Adipose, born from Roger's fat, would leave through the cat flap.

The Tenth Doctor visited Roger at this address, as part of his investigations into Adipose Industries. He pretended to represent them. Later, Roger was partially converted by parthenogenesis on his living room floor, but full parthenogenesis was averted in time by the Doctor. (TV: Partners in Crime)
