In rural areas and some urban areas like Androon e shehr Lahore.. people used to share walls and roof tops. There used to be window two houses at some places.
This seems to be fairy tale now? Have you ever observed such things in your life?
Don’t know much about inner city of Lahore, but this is definitely true for East End of London from late nineteenth century to pretty much all the way till 1940s or even later.
Why these things got changed? For Britain, it was the coming of Welfare system, economic growth, and rise in wages; post World War II development and reconstruction, housing boom, success of family planning campaigns and consequent drop in large families. So essentially, against a backdrop of economic reconstruction, all these factors contributed to the phenomena of ‘affluent working class’ that could afford better housing, have their own private space and live individualistic lifestyles.
Perhaps in some way, Pakistan is also going through this stage or will be in near future?
Pakistan is going through this phase, but here the reason might be different from England.
There is not that much economic growth, but attitudes have changed either due to lack of trust on your own people or due to copying of west blindly.
As far as inner city of Lahore concerned, I think many people migrated to posh areas after becoming well off. Even, red light area of Lahore saw this change after restriction placed during Bhutto and Zia era.
