This study delves into the issues of affordable housing and elements influencing the sustainability of affordable housing, with a specific focus on the Malaysian context. The primary objective is to identify the issues associated with affordable housing in Malaysia, as well as to determine the elements crucial for enhancing sustainability in the housing sector. A quantitative method using a questionnaire survey was conducted involving three groups of respondents: building designers, facility managers, and GBI facilitators. The research employed the Kruskal Wallis statistical analysis method and Importance Index Calculation as the key methodologies. Two significant findings emerged from the study. Firstly, the issues related to ‘location and accessibility’ and ‘financing challenges’ were identified as critically important, shedding light on the obstacles faced in these domains. Secondly, the elements of ‘adaptability and upgradability’ and ‘location and accessibility’ were highlighted as pivotal contributors to the sustainability of affordable housing in Malaysia. These findings provided valuable insights for policymakers, urban planners, and stakeholders in addressing key issues and promoting sustainable practices in the realm of affordable housing.
