Human: Please generate a brief description of a dreary scene inside a building armory with red carpeting, a wooden desk, and piping. Assistant: 
Large steel plates riveted to metal beams make up the walls, sending a rattle through the large room from time to time. Exposed piping runs through the ceiling, much of it rusted and giving off a slightly musty odor. A large wooden desk sits on a square of red carpeting, looking a bit out of place.
