One of the main problems in the social development of most third world countries is Africa, Asia and Latin America: economic underdevelopment, poverty, environmental pollution and high density all lead to an increase in informal housing, which is created as a result of the occupation of the land with no services necessary for life. This has led to an increase in crime, poverty, epidemics and infectious diseases affecting nearby settlements in the city. In 1970-1980 in the Sudanese capital Khartoum, infectious diseases such as cholera and Typhoid appeared, some citizens became building their homes in the sewers, which led to the death of many and caused the risk of flooding, as happened in 1988-1996. This occurring occurs in the absence of scientific planning for the development and development of the city and has a great impact on the development of the largest cities of Sudan and its capital Khartoum. The importance of research comes when looking at the centers of the old Sudanese cities, which surrounds the random housing and single-storey buildings that are free of intensive sanitation, as these buildings do not live up to the required level where the narrow streets and high population density and lack of a forestation and greenery and service facilities, so it is necessary to reduce this type of housing and this requires scientific stitching and planning of human settlements in the form of full-service housing groups and reconstruction. To solve this problem, sufficient scientific studies must be conducted that will lead to the work of an integrated program of planning and solutions that conform to the available possibilities and exploit local materials and develop them on scientific bases to perform the desired purpose. The results of the study proved that the architectural expansion of the architectural expansion, which consisted of the design of five-storey architectural apartments, has a significant impact on reducing random housing and the best use of land. It was found that multi-storey buildings with five floors are considered to be the economic and security situation, as the study found that 25.4% of the land was used and therefore provide 74.6% of land use.
