the" safe"
house (room)

A safe room or panic room is a fortified room which is installed in a private residence or business to provide a safe hiding place for the inhabitants in the event of a break-in, home invasion, or other threat.

“The idea of a “safe house” is something that has a particular resonance with me. They are supposed to be places where you are out of harm’s way but due to the fact that people only end up there as a direct result of some sort of forced upheaval of normal life, in my mind, they strike me as being cold and lonely. It’s a terrifying thought that in a flash you can lose your identity, your family, your friends.
