Introduction: This article examines social housing projects through the perspective of systems thinking, grounded in the contributions of Alexander Bogdanov's Tectology and Ludwig von Bertalanffy's General Systems Theory. The study is based on the recognition that Cartesian models, centered on fragmentation and predominantly quantitative goals, are insufficient to address the complexity of the Brazilian housing deficit. This qualitative and theoretical research relied on an extensive bibliographic and documentary review, including classical and contemporary references, legislation, and technical standards, with special emphasis on NBR 15575, which establishes performance requirements for housing buildings. The findings suggest that systemic thinking enhances the design of more integrated projects, capable of articulating multiple actors and variables. This perspective allows the incorporation of not only technical requirements related to safety, habitability, and sustainability but also social, cultural, and economic aspects directly associated with housing use. It is concluded that adopting systemic approaches, supported by tools such as Building Information Modeling (BIM), can significantly improve the quality, adaptability, and durability of social housing projects. Furthermore, systemic thinking may contribute to the development of more inclusive urban policies and to the promotion of long-term improvements in residents' quality of life. Objective: The objective of this study is to investigate the application of systems thinking in the conception and development of social housing projects, with the aim of identifying how this perspective can contribute to the formulation of more integrated, sustainable design solutions aligned with the real needs of users. Theoretical Framework: In this topic, the main concepts and theories that underpin the research are presented. The highlights include Alexander Bogdanov's Tectology, Ludwig von Bertalanffy's General Systems Theory, and the principles of systems thinking applied to social housing stand out, providing a solid basis for understanding the context of the investigation. Method: The methodology adopted for this research comprises a qualitative and theoretical study design, based on a bibliographic and documentary review of systems thinking, tectology, general systems theory, social housing, and housing performance, as well as relevant legislation and technical standards. Data collection was carried out through the systematic selection and analysis of academic publications, legal documents, and normative frameworks, which provided the analytical foundation for the investigation. Results and Discussion: The results obtained revealed that the application of systems thinking to social housing projects enables the integration of technical, social, cultural, and environmental variables, thereby enhancing the quality, sustainability, and adaptability of the built environment. It was also evidenced that the incorporation of performance guidelines, such as those established by NBR 15575, together with tools like Building Information Modeling (BIM), supports the development of more inclusive and effective solutions compared to the traditional Cartesian model. In the discussion section, these results are contextualized in light of the theoretical framework, highlighting the implications and relationships identified. Possible discrepancies and limitations of the study are also considered in this section. Research Implications: The practical and theoretical implications of this research are discussed, providing insights into how the results can be applied or influence practices in the field of social housing and sustainable urban planning. These implications could encompass public housing policies, the development of more integrated architectural and engineering projects, construction management practices, and the academic training of professionals in architecture, engineering, and urbanism. Originality/Value: This study contributes to the literature by applying systems thinking-traditionally explored in fields such as biology and management-to the context of social housing, highlighting its originality in addressing the complexity of housing projects through an integrative and interdisciplinary perspective. The relevance and value of this research are evidenced by demonstrating how the incorporation of systemic principles, together with performance standards and tools such as Building Information Modeling (BIM), can transform design and management practices in social housing, providing a basis for more inclusive public policies and improving the quality of life of residents.
