This study explores the typological characteristics of hospital ward design in selected Nigerian federal university teaching hospitals. It argues that this method is advantageous because it adds a typological component to the evaluation of existing buildings and offers insight into the architect's thought processes and design culture. Based on the idea of type as an abstraction and a logical principle that guides design, a morphological approach to typological analysis was undertaken utilizing six selected federal teaching hospital wards in Nigeria's six geopolitical zones. The findings from the analysis indicated the general characteristics and six typologies of ward design. The analysis revealed that hospital ward typologies are best described as low-rise architectures with corridoraccessed units grouped hierarchically around service centers. The six emerging typologies revealed the architects' design culture by revealing the aspects they controlled in these building types' design. Finally, the paper emphasized the significance of examining the typological features of these hospital wards.
