Housing design plays a crucial role in sustainable social development as cities face numerous challenges due to various changes in the physical landscape. Therefore, it is imperative to establish appropriate design indicators for residential towers. This study aims to investigate the design indicators for sustainable social development in residential towers in the metropolis of Tehran. The research method employed is descriptive-analytical and applied in nature. The statistical population for this study consists of architectural experts who are members of the Tehran Organization. According to the Engineering System Organization, the statistical population comprises 22,000 experts and members of the Tehran Engineering System Organization. The sample size was determined to be 384 individuals based on the Morgan table. The results of the Friedman test indicate that designing open spaces for art, culture, games, and entertainment in towers promotes interactions and a sense of belonging, while mitigating the negative effects of industrial life on residents. This aspect was found to have the highest weightage of 17.81. Additionally, the flexibility in tower design and overcoming structural constraints through solutions such as strip design and atrium design, along with facilitating proper access and installation of open spaces, contribute to sustainable development and enhance residents' satisfaction. This indicator obtained a weightage of 17.51. Furthermore, the effective management of towers and the design of suitable social spaces on roofs and ground floors (interactive, sports, cultural, and artistic) have a significant impact on reducing tower-related issues and promoting vitality and public participation. This indicator ranked third with a weightage of 17.42. Consequently, sustainable social development is closely linked to the design of residential towers.

In the age of knowledge, the rapid development of information and communication technology is considered as the main element to respond to the increasing urban environmental and socio-economic crises. Therefore, knowledge-based cities are cities that use technology and innovation to improve the quality of life of citizens and the efficiency of services aimed at sustainable urban development. Based on this, the current research was compiled with the aim of the impact of ICT use and capability on knowledge-based urban development. The research method is applied in terms of nature, in terms of the type of descriptive-analytical research (Structural Equation Modeling) and in terms of the type of post-event strategy. The method of data collection was library and field. The statistical population includes the experts of the Deputy of Urban Planning in 22 districts of Tehran Municipality, and the sample size was determined by targeted sampling of 220 people. Structural equation method and partial least squares approach and SmartPLS3 software were used to analyze the research data. The results indicated that the average variables of application and capability of information and communication technology and knowledge-based urban development of Tehran, along with all its components based on a 5-level spectrum, are in the range of 2.51 to 3.5, i.e., semi-stable. Also, the effect of the application and capability of information and communication technology on knowledge-based urban development has a significant coefficient greater than 1.96, and the path for the main research model is confirmed; Therefore, taking advantage of the application and ability to invest in the research and development of information and communication technology sectors can be a solution to remove the limitations of knowledge-based urban development in the metropolis of Tehran.
