From the point of view of studies predicting around 1.5 million missing dwellings in metropolitan regions in the coming years due to immigration, demographic change and changing living conditions, the further sealing of areas is quite understandable – but ecologically hardly justifiable for future generations. So what do…?
In addition to the construction of climate-neutral or climate-positive settlements, the right path is the one that legislators have been prescribing since the amendment of the Building Code in 2013: Inner development before outer development. In the interior areas of our cities there are indeed large areas of land lying dormant. In a recent survey conducted by immovativ GmbH and the German Society for Internal Development (DGI), the nearly 350 participating municipalities estimate their inner-city potential for land at an average of 5.3 percent of the settlement area. This is also in line with figures determined by the DGI in a current project in the Darmstadt-Dieburg district.
