Analytical Framework for Housing Typology Classification in Nigeria’s Middle Belt Cities

Housing typology classification is a foundational analytical tool for urban housing research, policy analysis, and architectural education, yet existing Nigerian housing typology frameworks have been developed primarily in southern urban contexts and do not adequately capture the distinctive building forms, tenure arrangements, and socioeconomic drivers of housing production in Middle Belt cities. This study develops and validates an empirically grounded housing typology classification framework for cities in Nigeria's Middle Belt region, with fieldwork conducted in Makurdi, Jos, Lokoja, and Lafia. Field surveys documented the physical form, spatial organisation, construction system, materials, tenure type, and occupant socioeconomic profile of four hundred residential buildings across stratified sample areas in each city. Multivariate cluster analysis of the field dataset generated a statistically robust typology with nine distinct housing type clusters. Analysis tested the explanatory power of the typology in relation to household income, settlement age, and cultural background. Results identify Middle Belt housing typologies as reflecting a specific intersection of Tiv, Igala, Idoma, Ngas, and northern Nigerian housing traditions that differ significantly from both Yoruba compound typologies and Igbo rectangular plan forms. The compound-family cluster and the plot-by-plot incremental urban cluster emerge as numerically dominant and distinctive to the Middle Belt urban context. The classification framework demonstrates predictive validity, correctly classifying 87.4 percent of an independent validation sample. The study provides both an academic resource for housing research and a practical classification tool for housing policy, planning surveys, and urban design guidelines in the Middle Belt.
