The Laundry is based mainly in Dansey House, an old office block in London. It was formerly home to MI5 before they moved out to The Dustbin.[1]
In The Atrocity Archives, Bob accesses the building for the first time via a secret door in the gents toilets of Mornington Crescent underground station[2], indicating Dansey House is in Camden. However, later Bob mentions in passing that it is located in Hackney[3]. It's possible the exact location of the building is being masked from the reader.
Features[]
Dansey House is considerably old, and one of its most unique features is a pneumatic messaging system[4]. It is described later by Bob as being "a Victorian rookery of cabbage-coloured plasterboard walls and wheezing steam pipes".
