This chapter addresses the significance of spatial methods in transdisciplinary urban sustainability and research, with a particular emphasis on the dynamic urban landscape of Bangkok. By employing a hybrid approach to methodologies, the study explores new avenues for comprehensively capturing the complexities of urban environments, encompassing both human and non-human elements. Through a series of experimental activities, including the case study of Ari Ecowalk, the research sheds light on the nuanced interplay between urban lives, materiality, and sustainability, offering valuable insights for addressing contemporary urban challenges. The Ari Ecowalk case study exemplifies a pioneering spatial methodology that engages participants in multi-sensory experiences, fostering a deeper connection with urban spaces and promoting ecological mindfulness. This innovative approach highlights the importance of community engagement and sensory exploration in enhancing urban sustainability practices and fostering a harmonious coexistence between urban development and natural environments.
