Hi Peter
Welcome to out little forum, thanks for your input, it's always good to hear from somebody who actually lived in these places. I didn't know anybody who lived in the Garrison Street flats although I did know a family that lived in the Palmer Street ones and I can remember from visiting them what tiny places they were and I lived in a back to back and it seemed small to me.
Earlier in this thread Planetmalc mentions the municipal flats that were in Wright Street Small Heath saying that he thought that they could be the first council flats in Birmingham.
I remember a few years back when Mikejee and I were trying to put names to his collection of photos after he lost his records in a flood this was one of the photos we got stuck on for a while, but I think Mike came across a story of them when they were about to be demolished. So perhaps he will remember more about the story of the flats than I do.
