Can't see it sorry. I don't have 'permission'. God know who does.
I'm not disputing its existence as police station, but a building that small with two doors strongly implies it was a toilet at some point in its existence.
Perhaps it was upgraded from toilet to copshop and new toilets built behind it?
I worry that you think any building with two doors is a toilet! It was built as a police substation and nothing else. How do I know this without relying on Google (as is the custom these days it seems)? Because as a kid I was taken in there by a police constable along with another lad for riding two on a bike. Had he taken two boys in a public toilet that would raise public concerns I am sure.
The door on the left led inside to the police office which as you can imagine was very small. The other door? Well in those days police officers either walked or rode bicycles and the door on the left was access to a small area where the police officer could safely place his bicycle. The public toilets at the back were nothing at all to do with the police substation. Totally unrelated .
