I dug out these few pictures from when I was in Latvia. This kind of block of flats was a standard across all Eastern Block countries. They all look similar and they all were famous for being badly built (there is a saying that for every block finished there was a house for the chief engineer – guess where he took the materials from).
Since the changes came in the 90’s I don’t think there was any more of those finished and some of the old ones gained some colour (at least in Poland). I suppose the construction of the building below must have started just before the system collapsed.
