I used to work in there, you can see where I sat, next to the window, top floor right hand side, a warren of corridors and passages, lost in time but behind me was a strong room, unable to do anything with it so they just took the door off and used it as an office. In the basement was the photo and printing labs for the council, you could not breath for fumes and could smell it distance away. To modernise it the council ripped all the interior walls out to make it open plan but one of the senior managers - second floor left hand side front, had the walls kept in his area and his office retained all the wood panelling. I know the lift area on the ground floor was used in TV programs as hotel scenes.
