those old commie blocks and 100 year old houses in "the village" are breaking down and people aren't filling them like they used to (not to mention the country's youth is moving to the cities to find jobs)
Do you mean the ones that Peterweg said would "last another 200 years" or the 1,000.000. properties that Milky states are standing empty.
I suspect you mean these :-
Most of the infrastructure of the blocks, be they strict microrayon groups, regular patterned groups or in haphazard arrangements depending on local geography, was constructed with generally low quality from water pipes and sewage to insulation and roof. The EAUE notes, "Most of the buildings have defects in the concrete slab construction and often the damage is irreparable. In addition, the areas are suffering from monotonous architecture and a lack of neighborhood contacts."[15] The first observation is physical in nature, the second psychological.
The physical problems with the buildings today are numberless: poor insulation on windows and in the buildings in general, the outside scraping off, poor plumbing and heating, disputes over ownership (and responsibility) of the common areas, small size of rooms and distance from amenities. The other imposing physical problem is that they are still occupied by residents as before the changes.[18] Poland and the entire former Warsaw Pact world faces interminable housing shortages, especially in the major cities. Ironically, Warsaw itself actually has more blocks of flats being built on the horizon, this time by capitalist developers, than it has destruction of old ones.[19]
