Quiet Rooms

Quiet rooms can be used for seclusion or de-escalation so design should be flexible to allow for such use. Seclusion rooms are single function rooms with an en-suite designed for low levels of stimuli and to prevent self-harm. Ceiling heights are typically 3m and all luminaries need to be robust, tamperproof and anti-ligature. The luminaires should be ceiling mounted and switched from outside the room.
