Navigating affordability challenges and opportunities in mixed-income housing: a case study of Cornubia in South africa. International Planning Studies. 30(1-2): 156-170. doi:10.1080/13563475.2025.24616621356-34751469-9265 (Online)https://hdl.handle.net/10321/5964This article offers a comprehensive exploration of the complex dynamics within the Cornubia mixed-income housing development. Positioned as a microcosm of challenges in creating sustainable living environments for affordable housing, the paper navigates through theoretical discussions to propose actionable strategies. The study employs a rigorous qualitative methodology rooted in a relativist perspective, utilizing semi-structured interviews, context-sensitive approaches, and local collaboration to delve into participants’ affordability challenges and the constraints/limitations of living in the Cornubia mixed-income housing. The findings, driven by the experiences of 254 low-income residents, illuminate two key themes on affordability: high living costs and affordable living in Cornubia. Findings highlight three factors that exacerbate high costs of living: Electricity, Water, and Transport. These multifaceted challenges underscore the urgent need for targeted interventions. In the context of sustainable development, the study identifies key areas for lasting impact, aligning with environmental sustainability and social equity goals.16 penAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/1205 Urban and Regional Planning1604 Human GeographyUrban & Regional Planning3304 Urban and regional planning4406 Human geographyUrban sustainabilitySustainable livingSouth AfricaCornubia neighbourhoodMixed-income housingArticle10.1080/13563475.2025.2461662
