What was in that gap: Knox street clinic carpark

Sometimes, you'd never guess that a gap once had something interesting. Other times, there are subtle clues, like this fence:

I'd had this photo for a while, and was puzzling over where this building could have been, and then I spotted the fence whilst out and about. What replaced this early Hamilton municipal building? A carpark!

Unfortunately, all my research on this building has come to nothing. All I've found is that the last photo above, taken in the '60s, was shortly before the building's demise. This is what the site looks like now - a car park with some old garages at the back. Most of the fence remains, but that's it.
