Construction is set to begin on the redevelopment of Berlin's former Tegel Airport into a technological research hub, residential district and nature reserve in the northwest of the city.
Named Berlin TXL – the Urban Tech Republic (Berlin TXL), the development will include a research park, landscaped area and Schumacher Quartier – a car-free residential district that will house up to 10,000 people.
Construction on the five-square-kilometer site will begin later this year, with completion of the first residential district scheduled for 2027. The project is led by the State of Berlin, which commissioned Tegel Projekt with the development and management of Berlin TXL and Schumacher Quartier.
Tegel Projekt calls Berlin TXL "a unique initiative in Europe" and aims for it to provide a sustainable model for modern urban cities that face a housing crisis. “This new blueprint for future city living will become available in the neighboring areas from now on," said the company. "Berlin TXL – The Urban Tech Republic is a unique initiative in Europe at the present time, if not in the whole world."
"In Berlin, as in many other cities, there is a shortage of affordable housing," said Tegel Projekt GmbH chief executive officer Philipp Bouteiller in a statement. "This causes people with lower incomes to be pushed out of the inner cities."
"Our vision is different: Berlin TXL should not be a place for a high-income clientele only, but a sustainable, liveable space for people of all ages and regardless of their income," Bouteiller added. The company says Schumacher Quartier – which will be located to the west of the airport tunnel – is an environmentally friendly, smart city. When complete, the residential area will have diverse housing options, with 10 percent of residential units reserved for student housing.
The development would include schools, daycare centers, shopping facilities and public spaces while a "low-energy network" would supply Berlin TXL with sustainable heating and cooling. The car-free district will also have its own bicycle lanes and bicycle highways, building on a campaign by Berlin Autofrei to make Berlin's center the largest car-free urban area in the world. Renderings of the district show buildings covered in plants as well structures surrounding open bodies of water.
German architecture studio Von Gerkan, Marg and Partners Architects (GMP), which designed the original brutalist buildings at the airport, will renovate the old hexagonal terminal buildings into the new research park. "In the Urban Tech Republic around 1,000 large and small businesses with 20,000 employees will work in research, development and production," explained Tegel Projekt. Nearly half of the entire space will be set aside as a nature reserve, with Gru?n Berlin responsible for the landscape development.
The brutalist Tegel Airport, which was given landmark status in 2019 was on the brink of closure since 2011 while the city waited for the arrival of Berlin Brandenburg Airport, which was postponed due to a series of successive delays. It eventually closed on 30 October 2020.
