From the first film to the sequels, the Elm Street House develops from simply being the place where the action takes to becoming the embodiment of Freddy in the physical world, taking on the characteristics of a classic haunted house and acting as a portal between the waking life and the dream world when characters steps in through the door of the house. In the original script from Dream Warriors, the house seen by the Elm Street children in their nightmares is revealed to not be 1428 Elm Street, but a ranch house where Freddy was born; this idea was omitted in the theatrical film. The novelization The Nightmares on Elm Street Parts 1, 2, 3: The Continuing Story, written by Jeffrey Cooper, uses the original script rather than the film script; thus, the ranch house also appears in the Dream Warriors chapter in the book. A non-canonical alternate backstory for 1428 Elm Street was featured in The Life and Death of Freddy Krueger contained within Cooper's novelization, where the house is described to have once have been a mental asylum where Freddy was born to an unnamed schizophrenic female patient who died in childbirth; the former asylum at 1428 is also present in Cooper's novelization of Dream Warriors, where it's called the Hathaway House.
