This study examines the use of landscape design to replace slums in residential areas. The research is based on a descriptive and analytical approach, drawing information from previous studies that have addressed landscape design to achieve sustainability in residential areas. The study aims to develop a comprehensive assessment of the use of landscape elements in an environmentally sustainable manner, focusing on site coordination, water, energy, soil, vegetation, maintenance operations, and materials. The research also considers the impact of landscape design on human well-being. The study was applied to the Rawdat Al-Sayeda Zeinab area in Cairo, and the results were compared with planned landscape designs to identify differences and necessary modifications. The study provides guidelines for using landscape design to achieve sustainability in residential areas and sets a direction for future research.
