This home is meant to be used at the start of the game, when you can't get either the Megaton house or the Tenpenny Tower room. It is located at the Springvale Red Rocket place in a sewer, has a downstairs, with a kitchen and place to sit, some books too, and an upstairs, with a bed, cabinet to hold guns and clothes, and a workbench for making weapons.
