Construction on a large new industrial and residential development project in Berlin, dubbed Siemensstadt Square, began on Tuesday with a groundbreaking ceremony featuring German Chancellor Olaf Scholz.
The new, approximately 76-hectare urban quarter is to be built by 2035 on the historic former industrial site of German engineering giant Siemens in the western Berlin district of Spandau.
Siemens was founded in Berlin, and its historical production facilities were located in the area, long known as Siemensstadt (Siemens City).
After World War II, Siemens moved the company headquarters and much of its production to the southern German city of Munich.
"The urban space should not just be a bedroom community, not just a working environment or just a shopping space," said Scholz.
The concept combining all aspects means that Siemensstadt will remain a place of the future and of confidence, the chancellor said.
"The exciting thing is that we are building the city of the future from an existing city quarter," said Siemens chief executive Roland Busch.
Around 35,000 people are to live and work in the new neighbourhood in the future, according to plans for the development.
Plans include the construction of apartments for around 7,000 people. An elementary school for 600 pupils and two daycare centers are also to be built.
A total of €4.5 billion ($4.8 billion) is to be invested in the area in the coming years, €750 million of which will come from Siemens.
Transport connections to Berlin's city centre are considered crucial to the planned revitalization of the Siemensstadt area.
German state-owned railway Deutsche Bahn is aiming to re-open a long-shuttered railway line to the Siemensstadt area by the end of 2029.
