As you well know, I was not referring to communist tower blocks -
Sorry, you need to be more precise next time because nobody knew it. We were talking about communist "slums" with Milo and suddenly you wrote that the ones built before 1960s were the worst. How should anyone know what you meant? :)
I wanted to write a few more things but looking through the posts I can see that they have been already mentioned by mafketis, Lenka, Kaprys and I generally agree with them.
Nottingham demolished it's slums 50 years ago.
Yes, but Britain wasn`t destroyed during WW2 as Poland. Fulfilling the housing needs in urban areas has always been a challenge here, since WW2.
People need houses, with gardens front and rear, driveways and a garage.
Easy, easy. Poland`s detached house population is 55% while British 85%. But in Germany, Spain, Italy, Switerland over 50% people live in flats so Poland isn`t so backward as you suggest.
