If you  disregard the perspective, you get the idea of how the loading dock is next to the Dry area. You can see the doorway between the 2 rooms in the middle of the wall between them.

At the far end of the Dock , is the way to the Chill. From there it is a right turn into the freezer, which is separated by the wall running down the middle and the wall at the far end of the Dry in the picture on the right.

The open wall is framed-out for the doors. The offices would be to your left, out-of-range of the photo; except for the right-angle at the far-left, which is the corner for Dispatch.
