Slums are the densely populated areas which are present in all the developed cities of the world. Pakistan is a third-world country and people from the rural areas prefer to live in the urban areas which are relatively better. This gave rise to urbanization and city space began to decrease. The development of slums in Pakistan initiated since the time of its establishment. Two of the earliest established slums are Goshala-Marrian in Faisalabad (the third largest city of Pakistan), Punjab. The built area of the city is greatly influenced by the establishment and growth of slums. This unplanned urbanization is required to be analyzed with respect to its physical elements, so that, the living quality of the inhabitants can be enhanced. The current living conditions were observed to plan for a better environment. Legalization of these areas is a mandate to be followed. The administration and the inhabitants need to put in joint efforts to upgrade the area.
