Concept
The large panel system-building is a building constructed of large, prefabricated concrete slabs. Such buildings are often found in housing development areas. Although large panel system-buildings are often considered to be typical of East Germany, the prefabricated construction method was used extensively in West Germany and elsewhere, particularly in public housing (see tower block). Prefabrication was pioneered in the Netherlands following World War I, based on construction methods developed in the United States. The first German use of large panel system-building construction is what is now known as the Splanemann-Siedlung in Berlin's Lichtenberg district, constructed in 1926–1930. These two- and three-storey apartment houses were assembled of locally cast slabs, inspired by the Dutch Betondorp in Watergraafsmeer, a suburb of Amsterdam. In East Germany, large panel system-building areas have been designated as Neubaugebiet ("New development area"). Virtually all new residential buildings since the 1960s were built in this style, as it was a quick and relatively inexpensive way to curb the country's severe housing shortage, which had been caused by wartime bombing raids and the large influx of German refugees from further east. At the same time, many buildings from earlier eras had substantial drawbacks, such as coal heat, no hot running water, or bathrooms shared by multiple units. As these buildings fell into disrepair, many of their inhabitants moved into newer large panel system-building housing. Today, large panel system-building are often no longer desirable, due in part to their rapid deterioration as a result of their cheap and quick construction methods, while older housing stock has undergone extensive renovation or been replaced with more modern dwelling units. There were several common large panel system-building designs. The most common series was the P2, followed by the WBS 70, the WHH GT 18, and Q3A. The designs were flexible and could be built as towers or rows of apartments of various heights.
