Definitely agree with you on that one, the fit out is reasonable for a brigade that size.
Starting from scratch will only be wasting valuable members time.
Believe they only in the last 12 months renovated the radio room.
The only perceived tight space is the turnout gear area, which probably could double to allow OHS complaint access and more members.

IF they end up having a new station...
A morphett vale replica would be pretty suitable, 4 doors, two each end.
Onkaparinga Bulk water carrier might even have a CFS home..
