The one-on-one treatment rooms are a set of four rooms used mainly for the purpose of treating the higher-risk patients and conducting initial interviews with new patients. Two chairs, a desk and a two way mirror on the wall are the only furniture within each room and they are laid out for maximum efficiency, with the same observation room being able to see into two interview chambers at once, allowing for a fully separated appraisal. While three of the two-way mirrors have survived (although one is badly cracked), the fourth has been completely smashed, allowing a clear view into the observation room.
