One of the biggest and grandest rooms in the hospital, the group therapy room was once used to treat many of the low-risk patients at once. A regular session saw them sitting in a circle and sharing their feelings with the group, though any semblance of a homey atmosphere is undercut by signs on the wall warning of constant doctor vigilance and directing patients not to touch any staff. A circle of roughly twenty chairs, some more stable than others, is arranged in the center of room, an example of the old treatment process that has been frozen in time. The decor in the room matches the elaborate design of the exterior of the hospital with a high-ceiling, large glass chandelier, and the corners of the room being designed to imitate pillars. Also in this room are many suitcases stacked high in one corner; name tags reveal they used to belong to patients and have been abandoned along with the hospital itself during the clean-up process.

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.

The art therapy room is located close to the entrance of the hospital itself. This was a considered decision; a large window provides a view of the hospital's front grounds, creating an atmosphere suited to one of the more peaceful therapy rooms. Only the most calm and trusted of patients were allowed to take part in these treatments. Given its location and nature, this would be one of the first things visitors and inspectors saw when they arrived. Now, though, the view of the grounds has turned against the room, with a fallen tree having destroyed the window and its branches breaking into the room, scattering easels along with the drawings and paintings produced by patients across the floor.
