Laundry site in central London, primarily used for storage and training. From the outside, the upper floor of the small building appears to be a three-bedroom flat with bricked-up back windows. But go through the door that should lead into the back bathroom and you will find yourself in a drafty space that comprises several thousand square meters of floor space within hastily assembled walls and ceilings of plasterboard and four-by-two. This space, now broken up into a peculiar and slowly shifting series of rooms, is all that's left of an attempt by a hideously powerful being to insert itself into our dimension.
The Laundry, after thwarting the attempt at the cost of three officers' lives, hollowed out the beast's extra-dimensional carcass and turned it into storerooms and a spare pistol range.
