Architectural design response to population issue in sub-Saharan cities

Abstract

Overpopulation is a serious global problem, and it is predicted to get worse in future if unchecked; accompanied with threat of dwindling resources. The increase in population and its effect on the housing sector is surfacing as clog in the wheel of efforts at reducing Africa’s housing deficits. How then can urban life continue to thrive in the existing housing issues in colonial, sub-Saharan city of Enugu, exploiting architectural design strategies is what the study investigates. It utilized a qualitative research approach of survey and participant observation in which data were collected and analysed based on thematic content analysis. Gross housing deficit, increased housing rent, emergence and expansion of squatter settlement, Land use conversion and slum conditions are some observable effects of population growth due to urbanization and rural-urban drift in the city; Statistics of public housing provision between 1999-2020, showed an over focus on high-income earners, neglecting the majority low-income population. Therefore, architect’s intervention in the housing sector should be strategic, holistic and proactive and encourage use of local materials, vertical development, dry construction and stakeholder’s participation in delivery process. The study concludes that futuristic architecture holds the key to humanity’s continued stewardship on earth and a sustainable housing delivery.
