Internally the main focus of the building is its large central foyer that has a large fireplace, timber panelled dados and an intricately carved timber staircase, over shadowed by a large stained glass window depicting a life size Robert the Bruce. The principal rooms located at ground level are the formal reception and dining rooms, and the governor's study. Each of the rooms is substantially intact; however, their decorative schemes have been subject to several refurbishments. Original furniture from the Old Government House still remains in these rooms.
