Wünsdorf itself will become a place of residence for visiting researchers, employees and staff, and the Eco City will presumably require the opening up and development of further areas outside the current planning area, where start-ups, research institutions and local businesses will be located, so the issue of gentrification must definitely be considered.
However, a major gentrification issue would also be the uncontrolled sale and development of land to investors who develop the former military city into housing for Berliners* who are simply looking for cheaper housing and do not have much of an emotional attachment to the place.
