Sustainable architectural solutions for affordable housing in Nigeria: A case study approach

Abstract

This study provides a critical examination of sustainable architectural solutions as a response to Nigeria's pressing affordable housing crisis. With the country facing rapid urbanization and a significant population increase, there is an urgent demand for housing solutions that are not only cost-effective but also environmentally sustainable. The research adopts a qualitative approach, utilizing a comprehensive review of existing literature, in-depth case studies, and the analysis of current trends to evaluate the feasibility and challenges associated with the implementation of sustainable architectural practices in Nigeria. The findings indicate that locally sourced materials, such as stabilized earth blocks and interlocking bricks, offer a viable means of reducing construction costs while supporting environmental sustainability. Moreover, the integration of renewable energy technologies, particularly solar power, has been identified as a key factor in lowering long-term energy expenses and enhancing the overall resilience of housing developments. Despite these promising strategies, the study identifies significant obstacles to widespread adoption, including financial constraints, a shortage of technical expertise and the gradual decline of traditional building practices. These challenges suggest the need for a holistic approach that includes the adoption of circular economy principles, the exploration of sharing economy models, and the deployment of advanced technologies like artificial intelligence and machine learning to improve the sustainability and affordability of future housing projects. The study emphasizes the importance of continuous professional development, robust policy frameworks and the active participation of all stakeholders to effectively address the housing challenges in Nigeria. These recommendations aim to foster a collaborative effort toward achieving sustainable and affordable housing solutions that meet the evolving needs of the population.
