Claim:
A prefabricated temporary house addition designed for transporting as a pre-constructed (Factory Built) re-usable modular structure to a user's residential house for removable temporary attachment thereto with a minimum amount of modification to the house and yard, thereby to provide the user with additional residential living facilities on a lower level of the user's house, wherefore the construction and appearance of the house addition is intended to be suitable for attachment to a house in a residential area; the prefabricated temporary house addition comprising: a Factory-built housing module comprising a room portion and a collar portion fixedly assembled together and transported as a non-collapsible unitary structure; wherein: the room portion is self-enclosed by rigid building materials comprising: a floor, a roof, two side walls laterally spaced apart to a fixed room width RW, and a back wall and a front wall affixed between the side walls, the front wall having a doorway opening therethrough; and the collar portion is self-enclosed by rigid building materials comprising: a floor, a roof, and two side walls having a fixed collar length OL and being laterally spaced apart to a fixed collar width OW that is substantially less than the room width RW; and further wherein: the collar portion is unchangeably affixed to the front wall of the room portion surrounding the front wall doorway opening to provide a hallway longitudinally extending from the room to a distal collar front end opening; and the collar has a mating surface around the collar front end opening that adapts the collar for temporary joining of the prefabricated housing module to an exterior wall of the user's residential house around a doorway opening provided therethrough; thereby minimizing modification of the user's residential house while making additional residential living facilities accessible by the user on a lower level of the house.
