The twin problems of uncontrolled urbanization and shortfall of afordable housing for low income groups are the bane of almost all developing countries. This is true in case of Pakistan undergoing rapid urban transformation with 207 million population at present. According to UN resources, half of the country’s urban population i.e. more than 27 million people continue to live in informal settlements. Lahore being the second largest city, is home to 11 million people, covering more than 300 informal housing settlements in the form of slums and squatters.
