shotgun hut
(chiefly Southern United States slang) A one-story house in which each room is in a straight alignment with the others, connected by a continuous hallway running from the front to the back of the residence. When our whole family goes to stay in my grandmother's shotgun hut in New Orleans, it always feels like we're all right on top of one another.
