Water is one of the most important renewable natural resources, and the extent of its renewal depends on the rate of its consumption compared to its depletion as a result of misuse - or exposure to pollution, and water conservation is one of the most important areas of sustainable development globally. Egypt, like other countries, suffers in recent years from severe water scarcity and a decrease in its per capita share of it. 97% of the Nile River water, the lack of rainwater falling inside Egypt, and the rise in temperature, which leads to an increase in water consumption in all uses, and an increase in the severity and frequency of extreme climatic phenomena such as torrential rains, and a rise in sea level that threatens the Nile River Delta by affecting coastal areas and submerging low lands, as well as the intrusion of salt water, which affects the salinity of water. groundwater in the northern delta.      Vertical gardens are one of the solutions of contemporary interior architecture that has moved to the interior spaces to realize its multiple benefits, including rationing the use of irrigation water for indoor coordination plants, and it requires sufficient awareness of the structural and design method for it, drainage and feeding processes, taking into account the insulation system, and its construction loads. The research studies vertical gardens as one of the methods of rationing water use in the interior architecture system, including the most important design considerations for it, to obtain its multiple benefits in contemporary interior spaces, which include the environmental aspect, and the design aspect, where it can be exploited as central points of attraction in the interior spaces.
