Berlin accident hospital and the Augenklinik Marzahn eye clinic, both of which provide care for patients far beyond the borders of Berlin and the region. Industrial and commercial parks with good transport connections make the eastern outskirts of Berlin interesting for companies from other business sectors as well. For example, with an area of approximately 90 hectares, the CleanTech Business Park in Marzahn is the most extensive contiguous site of manufacturing company locations in Berlin. Georg-Knorr- Park – the biggest project for further commercial and residential development – is now taking shape in Marzahn-Hellersdorf. Among other things, plans call for the construction of around 1,000 residential units, as well as 370 student apartments and commercial space for leasing. At least half of the residential units subsidise publicly. The master plan for Georg- Knorr-Park got complete in 2020.
