Public parks are vital for community well-being, yet often fail to cater to the needs of people with disabilities, restricting their safe and independent use. This paper details a pragmatic study aimed at crafting the design for an inclusive park on the outskirts of Bangkok, addressing these limitations. Through a comprehensive mixed-methods approach—encompassing literature reviews, semi-structured interviews, and surveys with stakeholders, including individuals with disabilities—this research gathered diverse perspectives on inclusive design. Participants underscored the importance of social and recreational activities in universally accessible spaces, providing valuable spatial insights. This research aims to employ pragmatic research methods to develop the design of an inclusive park for people with disabilities at the Thammasat University Rangsit Campus Water Sport Center. This study seeks to integrate the perspectives and needs of people with disabilities into the park design, ensuring that the space is accessible and meets a wide range of needs. The research aims to bridge socio-environmental considerations with practical design applications, creating a model that can serve as a template for similar developments in other urban settings. This study’s findings informed the creation of a design that harmoniously integrates green spaces with the specific requirements of disabled users, promoting inclusivity and accessibility within the fast-growing urban areas of Southeast Asia. This research not only offers a template for addressing the gaps in public space provision for people with disabilities but also illustrates how designers can interpret and meet socio-environmental and health-related needs through inclusive planning. It extends the discussion on overcoming WHO-identified inequalities in urban settings and lays the groundwork for interdisciplinary studies aimed at enriching the fabric of urban life through research processes and scientific inquiry. This paper asserts the pivotal role of inclusive design in enhancing urban livability, advocating for a design methodology that responds to the nuanced demands of inclusivity, thereby contributing to the broader discourse on equality, accessibility, and the right to the city for people with disabilities.
