This study explores the architectural, social and spatial characteristics of staff housing units built in Erzurum during the Republican Period. Throughout this period, the city center became home to numerous buildings belonging to public institutions, including entire campuses, many of which incorporated staff housing units. A comprehensive analysis was conducted, examining the relationship of these housing units with their campuses, their plan structures and façade designs. The findings reveal that the staff housing units predominantly reflect a modernist design approach. However, the demolition of certain units and the repurposing of public lands underscore the urgent need to preserve the remaining staff housing units and to develop future-oriented policies for their protection. Furthermore, given the increasing housing shortage, skyrocketing rents and rising inflation, the value of existing staff housing for civil servants becomes even more critical. This study highlights how Erzurum’s staff housing units offer a thematic perspective on Republican architecture and significantly contribute to the country’s housing culture.
