Airport Frankfurt
With almost 60 million passengers (2023), Frankfurt Airport is Germany's largest and Europe's sixth largest airport. In 2026, passenger numbers, which have fallen due to the pandemic, are expected to return to pre-crisis levels (~70.5 million) and continue to grow from then on.

Extension of the subway line U5
For decades, the current U5 subway line connected the eastern city center with the east and northeast of Berlin. Plans to extend the line to the west date back to the 1970s, but it was only with the reunification of Germany that these could be realized.

EDGE East Side Tower
The Berlin skyline is growing and another building was added in November 2023. With the 142 m high EDGE East Side Tower Berlin near ‘Warschauer Brücke’, one of Berlin's tallest buildings was built in just under 4 years. Particularly striking: the staircase-like curtain wall with almost complete glazing.
