This study investigates governance mechanisms shaping affordable housing delivery systems using a PRISMA-based systematic review that integrates architectural and urban planning perspectives. A total of 347 records (2015–2026) were retrieved from Scopus and Web of Science, of which 52 studies met the inclusion criteria. Guided by Institutional Theory and Sustainable Transitions Theory, the study employs a mixed qualitative–quantitative synthesis, including inferential regression analysis, to examine relationships between governance variables and housing affordability. Findings indicate that governance structures, particularly public–private partnerships (PPPs), land-use regulation, and institutional coordination, are the most influential determinants of affordability. Quantitative synthesis suggests that integrated governance frameworks are consistently associated with substantial cost-efficiency gains across housing systems. At the same time, regression results confirm governance as the strongest predictor, followed by PPP effectiveness, land administration, and design innovation. Architecturally, design standardisation, passive strategies, and material efficiency improve cost and lifecycle performance, while planning systems enhance regulatory coherence and infrastructure integration. However, weak institutional capacity and gaps in policy implementation remain critical barriers, especially in Sub-Saharan Africa. The study presents a validated governance–design framework to improve sustainable housing delivery outcomes.
