Urbanization is considered as one of the biggest challenges being faced by world today. It is estimated that currently more than half of the world's population is living in urban areas and this proportion is expected to rise in the near future. Therefore, one of the Sustainable Development Goals (SDGs) focuses on urban development i.e. Goal 11 which aims at 'making cities and human settlements inclusive, safe, resilient and sustainable'. For the housing, the main target within this goal is 'to ensure access for all to adequate, safe and affordable housing and basic services and upgrade slums'. The expansion of urban areas with increasing concentration of people puts pressure on the existing urban infrastructure which further leads to the problem of housing shortages, inadequate access to the basic services, overcrowding etc. On the other hand, there are very limited capacities of the towns and cities to provide every facility to the migrants, which resulted in the creation of slum areas.
