Shaft
At Columbia, shaft refers to the vertical passageways through buildings (and between buildings) around which many rooms have windows. These shaft rooms are often highly undesirable.
List of shafts
- 47 Claremont, one on either side of the building
- South shaft is wide because it opens out onto the adjacent shaft of a Barnard residence hall.
- North shaft is much narrower, with little light.
- McBain, the most notorious shaft at Columbia
- Broadway, not really a shaft
- Floors 3 and 4 have a very wide shaft at the center of the building
- Floors 5 and above are arranged around a U-shaped corridor
