This chapter offers a comprehensive exploration of architectural public spaces through a transdisciplinary lens, focusing on morphology, security, and daylight. In the context of urban development, these spaces play a vital role in shaping social interactions, fostering community cohesion, and enhancing the quality of life. The transdisciplinary approach adopted in this research integrates insights from environmental psychology, sustainable architecture, landscape design, architectural anthropology, spatial analysis (space syntax), perception theories, and concepts of self-security. This paper illuminates the complexities involved in the design, usability, and impact of these spaces, aiming to bridge existing knowledge gaps. It further provides practical recommendations for architects, urban planners, policymakers, and other relevant stakeholders. By merging diverse disciplinary perspectives, the paper underscores the importance of a transdisciplinary discourse in the design and utilization of architectural public spaces, contributing to a broader understanding of urban life quality and sustainability.
