Dusseldorf A good 14,000 houses were demolished in Germany in 2021, reports the Federal Statistical Office (Destatis). The number of unreported cases is likely to be significantly higher because the demolition of many single- and two-family houses does not even have to be approved. According to German Environmental Aid (DUH), there are far too many. Federal Managing Director Barbara Metz speaks of a “demolition mania”.
The DUH and other organizations such as Architects for Future and the Association for Existing Buildings (BiB) are calling for the preservation of buildings to be made more attractive. This is possible through a permit requirement for demolition in the model building regulations and the state building regulations, Metz said at a press conference this week.
