The concept of housing in many countries has become more comprehensive than many simple considerations by which the house itself can be defined. The concept has expanded to include the possibility of achieving housing for economic, social, and urban appropriateness, although housing from the point of view of some people sees housing as a product or commodity that has material characteristics in terms of price and construction costs only, the goal of housing projects should not provide housing only, it must meet multiple economic, social and urban needs, as housing is a system in which the economic, social, urban, organizational, administrative, design and planning aspects are integrated, and any deficiency in one of them leads to a defect in the plans and projects raised to solve this problem. It is worth noting that housing policies used in some countries, including Egypt, do not cover some or all of the previous aspects, which entails the emergence of many housing problems in each of them, especially in the field of affordable housing projects and then many countries of the world have developed various plans and projects to subside and funding for low-income and poor families to obtain adequate shelter is at its lowest levels
