In postwar Shimonoseki, improved housing complex (13 buildings with 593 units) was constructed through the mix enforcement of a land readjustment project and two urban redevelopment projects for urban residential renewal. This study examines the historical meaning of this Shimonoseki Ekimae Urban Renewal from the perspective of housing design. As a result, the historical positioning of the urban renewal is clarified, and it is shown that the development was an urban design practice that reorganized urban space through housing under district-scale city planning, and that the improved housing is a concrete postwar architecture that demonstrates this planning technique.
