The first example of this building type was erected in 1971 at the Holzmarktstraße in East Berlin. With the redevelopment of Fischerinsel, modified version of this series were built. From 1972 onward they were used in almost all East Berlin housing development projects. In contrast to the mostly 11-storey building with buildings of WBS 70 these buildings dominated high-rise urban construction. They were built near major road intersections, or in the vicinity of high capacity public transportation, such as subway or train stations.
