In light of the wars and disasters in the world as a whole and in the Arab world in particular, especially those displaced by the Israeli aggression on the Gaza Strip in 2023, there is great difficulty and hardship in providing shelter in suitable conditions. In most cases, temporary housing units are of a very limited area and do not provide the basic needs for a decent human life. From this standpoint, this problem requires the provision of design plans and solutions to meet the basic needs of the displaced in temporary housing units and improve the user experience. Here lies the role of the interior designer in finding solutions and addressing the interior space, in a way that achieves the desires and needs of users within the limited space available and transforms them into comfortable and practical spaces, taking into account the economic and environmental aspects, the culture of users and all expected challenges. Accordingly, we find that there is a need to educate individuals about the importance of the role of smart furniture in improving the user experience in temporary housing units. The study aimed to identify the importance of interior design to meet the needs of the displaced in temporary housing units with limited space, in addition to the role of smart furniture in improving the user experience of these homes, which works to improve the quality of the interior space of these housing units. The study reached many results and recommendations, the most important of which is that the use of modern smart technology in the interior design of temporary housing contributes to enhancing the efficiency of these housing units and makes them more suitable for the needs of the displaced, as it improves the user experience of the interior space. The study also recommended taking into account the selection of interior furniture that does not require a long time to design and implement, and is also characterized by ease of disassembly, assembly and transportation, achieving privacy and taking into account the cultural and social customs and traditions and religious teachings of the displaced people of the Gaza Strip.
