Most of the Safe humanoid SCPs have some kind of containment rules to the tune of "room X by X by X, all requests blah blah blah" which can get repetitive. An idea would be to classify these into more standard requirements. For example:
Holding Cell - A bare concrete holding cell with built-in bed and facilities. For ornery or misbehaving SCPs.
Quarters - Bedroom/study and bathroom. Similar to a single-person hospital apartment. For the average SCP.
Luxury Quarters - Large bedroom with adjacent study, kitchen/dining area, sitting room and bathroom. Similar to a luxury hotel suite. For SCPs with special arrangements with the Foundation.
