Public spaces in residential areas can be considered as a key controller of people's behavior. As these spaces motivate people to socially interact this by the way tailor their personality and mental processes. Besides, this interaction affects the quality of life of individuals and the way they interact with the environment. Accordingly, it is essential for architects to pay more concern to the design of open areas with more consideration to human aspects rather than just physical aspects only. Moreover, the goals and principles of sustainability, especially social sustainability has to be considered. This attributed to the strong relationship and mutual interaction between human needs, design dimensions of residential open areas and principles of social sustainability. However, in some countries, including Egypt, there is a wide shortage in the proper design of open areas within residential communities as the buildings seem to be scary solid blocks. Accordingly, the individuals misally use the islands in the public streets and squares considering them as open areas. This study aims to solve this issue and avoid this misuse. One of the proposed solutions is to study residential open areas aiming at achieving human needs besides providing appropriate urban design elements. This can be performed by investigating the relationship between human needs and urban design elements in residential areas, as well as linking them to the basic principles of social sustainability because it is the link between urbanization and humanity. Moreover, the study presents a proposition to the effectual aspects that can both achieve a successful design of public spaces and fruit human welfare. These aspects include geographical, physical, psychological, and managerial concerns. Each aspect was divided into several requirements. Then, the proposed relation between human needs, principles of design and sustainability to residential open areas is correlated through the satisfaction of these requirements. In order to examine the efficiency of the excluded principles the people's park were taken as a case study.
