Other forms: panopticons
If your school is designed as a panopticon, it means that if you stand in the middle of the building, you can see every single classroom.
Use the noun panopticon to talk about a circular building — especially a prison with cells distributed around a central surveillance station. Eighteenth century philosopher Jeremy Bentham dreamed up the idea and was kind enough to bequeath us the word as well, from the Greek pan, or "all," and optikon, "of or for sight."
