Efforts to secure sustainable housing for low-income earners constitute a persistent challenge in addressing housing deficits, particularly in developing economies. This study systematically examined the current state of research on sustainable housing for low-income communities, identified gaps, and proposed innovative implementation strategies and comprehensive frameworks. The mixed-methods approach (a systematic literature review (SLR) and meta-analysis) was implemented, and the study was conducted according to PRISMA guidelines with the PICOS framework being followed to provide rigor and transparency. The review summarized evidence from 48 peer-reviewed articles published between 2000-2024. Key findings were categorized into six thematic areas: challenges to sustainable housing, innovative strategies, energy efficiency, indoor environmental quality, sustainable building materials, and the development of comprehensive frameworks. The governance related barriers, the high initial cost of renewable energy technologies and lack of lifecycle assessment of sustainable building materials were noted as major barriers. The use of public-private partnerships, modular construction, and use of locally available materials proved to show significant potential in increasing sustainable housing provision. This study contributes to literature by consolidating fragmented research and highlighting gaps in empirical findings. The originality of this work lies in its dual methodology, which combines systematic review with meta-analysis to provide a robust and holistic understanding of the factors influencing sustainable housing.
