If Slytherin built the Chamber of Secrets, the pattern implies Gryffindor built the Headmaster's office (guarded by a griffin with a spiral staircase), Hufflepuff built the Room of Requirement, and Ravenclaw encoded her genius into the 142 ever-shifting staircases. It turns Hogwarts' architecture itself into a four-part cipher of the founders' personalities.
