Architects and urban designers face many dilemmas when they designed any residential complex or a suitable residential environment, and these dilemmas or problems were represented with a batch of urban challenges that are associated with the rapid development of the cities and may become obstacle in front of them when designing and implementing their projects. Some international organizations including the United Nations, has raised some of these problems and put solutions to them, while others are still marginal or without radical solutions. Research has submited the most important challenges in residential environment and categorised them into three main types, namely, (urban challenges associated with human need, urban challenges associated with residential environment, and urban challenges at the urban level). One of the most important challenges that must be taken into consideration when designing is the chellenge of providing safety and security in residential environment, where the need of security and safety represents one of the most basic human needs that provides human tranquility and a sense of stability when available. The research problem was that there was no clear vision about the role of spacial organization to achieve safety and security in residential environment. The research aims to identify the elements of spacial organization in raising the level of safety and security in the residential environment, and it based in achieving this goal to hypothesis, which is spacial organization had role in raising the level of safety and security in the residential environment through its local and globale characterstics. The research had identified the impact of special organization charachterstics on raising the level of safety and security in the residential environment, also it came out with new items which were not mentioned previously, those are (Visibility), (Visual Depth) and (Visual Integration) and the impact of those items on the availability of residential safety and security. The research had identified the most important variables affecting the human sense of security and safety, it also concluded that achieving security (which is psychological) comes through the availability of security (which is materialistic) resulting from the design and its vocabularies, one of it is the vocabularies of spacial organization and the synthetic properties of urban structure.
