Housing is one of the most important needs of every human being. Without housing one would be exposed to adverse effects resulting from vagaries inherent in an environment. Exposure to bad weather would lead to hill health. Housing fosters the development of other industries. The building industry produces buildings for utilities, shops and communal facilities. Housing is also a tool for economic development. Industrial production would be hampered if the labour force is not housed.

Shortage of housing is a big problem becoming an enduring feature in many countries. This problem has been exacerbated by high rates of population growth and internal migration to urban areas in search of greener pastures. The extent of such a problem varies with urban centers but the results are the same: high population densities, sanitation problems, unhealthy living conditions and insecurity of tenure (Seong-kyu, 1987).
