Erfurt-Southeast (German: Erfurt-Südost) is the collective name for a series of prefabricated housing areas that emerged in the southeast of Erfurt in the last ten years of East Germany.[citation needed] After Erfurt-Nord, Erfurt-Südost is the second-largest prefabricated building area in the city. The problems associated with large housing estates are not as pronounced in the southeast as in the north, but they are still present.
