Richter Hall is a building at Redwood Dorm on campus of fictional DeMontfort University in Vince Suzukawa's comics series The Class Menagerie and i.s.o. The building was sarcastically named by the author in reference to the Richter magnitude scale.
Originally a five-storey building, the top two floors and much of the third floor of Richter Hall were destroyed in an accident years previous, officially explained as the result of an earthquake. The remaining parts of the building were salvaged and repaired, and it continued to function as a dormitory.
However, Richter Hall has a reputation of being one of the least desirable dorms on campus, and is usually the last on-campus living space to be filled.
The first floor is all-male, and is the setting of i.s.o. The second floor is all-female, and includes the women's bathroom. The remains of the third floor are co-ed, including a men's bathroom and the living spaces of all the main characters of The Class Menagerie. The destroyed portion of the third floor has no ceiling, and is effectively the roof above the second floor.
