The topic of the “city of tomorrow” concerns everyone: whether you are a municipal planner in Berlin, a landscape architect in Hamburg or a representative of the real estate industry in Munich. Everyone is equally interested in the future of our cities. Last week, 120 municipal planners and landscape architects and six expert speakers took a joint look at the future of urban development.

The topic “The city of tomorrow” concerns everyone: whether Berlin municipal planners, Hamburg landscape architects or Munich representatives from the real estate industry. Everyone is equally interested in the future of our cities. But how do we meet the climate challenges of tomorrow? What does sustainable urban development look like in the 21st century?

Last week,120 municipal planners and landscape architects and six expert speakers took a joint look at the future of urban development. The focus of the one-day congress “Zukunft Stadt@GRÜNBAU BERLIN” was on providing information and networking. Inclusion – what does that actually mean? Making space for water! But how? What positive impact does light have on its surroundings? – Questions like these were the subject of lively discussion.

Ute Eckardt, Office for Urban Greenery and Waste Management, Dresden, kicked things off by presenting the inclusive playground as a place of encounter, communication and togetherness. “Every playground and every exercise program promotes inclusion,” said Eckardt. The most important principle is barrier-free accessibility of the open space. In addition to accessibility, she formulated five other key aspects for the planning of an inclusive playground: the participation of all potential users, the variety of offers, the consideration of the entire neighborhood, the planner’s change of perspective and the promotion of togetherness.

Martina Hoff, Landschaftsarchitekturbüro Hoff, Essen, then presented best practice examples from her everyday work as a planner, such as the Park der Generationen in Witten-Annen and the Lutherpark playground in Witten. Her three basic rules of inclusion: the wheel-feet rule (obstacle-free accessibility), the two-channel principle (always appeal to two senses) and KISS (Keep It Short and Simple).

Green, greener, “DIE GRÜNE STADT” foundation

Peter Menke, “DIE GRÜNE STADT” Foundation, spoke on the topic of “Green and open spaces in the city of the future”. He began with the quote “The success of the city is essentially determined by the quality of the spaces in between” (Martin Haas, Studio 2050) and explained the importance and value of green and blue elements in the city. “Green promotes health, ensures social functions and greatly enhances the quality of the location,” said Menke.

Giving water space

Dieter Grau, Ramboll Studio Dreiseitl, dealt with the functional and aesthetic networking of rainwater management in his presentation. He spoke about the consequences of climate change, such as periods of heat and drought, extreme rainfall events and flooding. He emphasized that these challenges will have to be taken into account in urban planning in the future. In addition to his projects, Zollhallenplatz in Freiburg and Potsdamer Platz in Berlin, he presented research projects from the metropolitan regions of Hamburg and Copenhagen, two cities whose infrastructures are at their limits as a result of climate change.

Luminosity and the city as a stage

“Artistic illuminations contribute to the culture of public spaces, create character and, thanks to their modern lighting technology, contribute to greater aesthetics and energy efficiency.” This guiding principle is the starting point for the funding projects of the “Lebendige Stadt” foundation, which Gerhard Fuchs reported on at the Forum for Urban Development.

Martin Rein-Cano, Topotek 1, spoke about the city as a stage in the concluding presentation. He presented colorful street furniture and unusual projects. The starting point for their planning was not only function, but above all attractiveness, so that the urban space in question is accepted by the people. For the 2009 Federal Garden Show in Schwerin, the landscape architects from Topotek 1 designed a picnic area half in the water, for the campus of the Martin Luther University in Halle in 2002 a multi-purpose concrete bench and for Chemnitz Central Station in 2016 a neon-colored waiting area with various seating elements.

Zaha Hadid builds Tokyo’s Olympic Stadium – but not after all

Back to square one in Tokyo: Zaha Hadid Architects will not be building the central stadium for the 2020 Olympic Games after all.

It’s back to square one in Tokyo: Zaha Hadid Architects will not be building the central stadium for the 2020 Olympic Games after all. Japan’s Prime Minister Shinzo Abe has now declared that the entire process will be reset to zero for cost reasons. “We are starting all over again,” the Guardian quotes the Japanese politician as saying. So there will probably be a new competition.
Ultimately, however, the ever-increasing construction costs are likely to be just one reason for the decision. Architecturally, the extravagant building (Hadid, that is) also came in for a lot of criticism – not least from other architects. Arata Isozaki had described Hadid’s design as a turtle just waiting for Japan to sink into the sea so it could swim away. Pritzker Prize winner Fumihiko Maki had organized a symposium against the design, which was attended by Toyo Ito, Kengo Kuma and Sou Fujimoto, among others. A petition against the building was also initiated.
Patrik Schumacher, the first architect in Zaha Hadid’s office, apparently holds this architect-dominated counter-movement partly responsible for the decision. He wrote on Facebook: “Maki and Ito will be remembered for this.”

The center of Berlin remains green

RMP Stephan Lenzen win the open space competition for the City Hall and Marx-Engels-Forum in Berlin: The office won against 52 other entries.

It’s all about a prominent area in Berlin’s historic center: sandwiched between the new Humboldt Forum and the television tower, the Rathaus- and Marx-Engels-Forum are getting a new design. The RMP Stephan Lenzen office has won the competition for the green center of Berlin.

Where the roots of the city of Berlin lie, there will soon be no new construction. The open spaces of the Rathaus-Forum and Marx-Engels-Forum will remain green. However, the area will be given a new design, which will result in a flight of steps leading down to the adjacent Spree. The Berlin Senate Administration invited people to take part in a competition in the spring. After an initial phase, citizens were allowed to have their say. A total of 21 landscape architecture firms then developed their ideas further in the second phase of the competition. The landscape architects from RMP Stephan Lenzen ultimately won over the jury. They proposed a central ribbon that connects listed areas of the Rathausforum with the Marx-Engels-Forum. This green ribbon ends in a large staircase on the banks of the Spree. Opposite, on the other side of the water, the eastern façade of the new Humboldt Forum shines.

The open space in the middle of old Berlin used to be called “Park an der Spree”. As one of the most central green spaces in the Mitte district, it dates back to the Second World War. It damaged the Heilig-Geist-Viertel, which ultimately prompted the GDR leadership to demolish it. Since then, the area between Karl-Liebknecht-Straße in the north, the park by the television tower in the east, Rathausstraße in the south and the Spree in the west has remained undeveloped. For a long time, there was an ensemble of monuments in the middle of the area, but this had to be moved to the north-western edge when the subway was built. The future of the Marx-Engels Forum has been under discussion since the 1990s. The ideas were many and varied. They ranged from the reconstruction of the Heilig-Geist-Viertel to the design of a park at the Marx-Engels-Forum. The latter ultimately prevailed.

Marx-Engels-Forum competition brief

The design of a park on the Marx-Engels-Forum now had to be fleshed out as part of the ideas and realization competition. The participants were asked to engage with the place where Berlin was founded, the historical layers hidden in the ground and the surrounding area. At the end of the long debate about the future of this site, citizens’ guidelines for the future development of the Rathaus Forum and the Marx-Engels Forumwere drawn up . These guidelines state that an open space should be designed that does justice to the dimensions and significance of the location and strengthens the identity of the site. In addition, it should bring the eventful history to life and at the same time enable diverse and intensive uses.

In the first phase, the competition initially asked for a vision and an idea for the entire Marx-Engels-Forum. Only the participants in the second phase had to derive their vision. In addition, they outlined an intermediate state for the year 2030 in the ideas part of the competition. In a third realization part, the concrete implementation for 2024 was then to be shown. This step-by-step approach is based on the intended gradual realization of the project. This will take a long time. Accordingly, the ideas must be based on a clear approach and offer a great deal of flexibility for process-based implementation.

The landscape architects from RMP Lenzen provided the most convincing solution for the new design of the Rathaus- and Marx-Engels-Forum. They designed an open space that is characterized by a striking figure. The plan is to keep the Rathaus- and Marx-Engels-Forum free of buildings. The green space promises a high quality of stay with areas for strolling, relaxing and enjoying spectacular views of the cathedral, Humboldt Forum and television tower. RMP Lenzen is equipping the new space with plenty of greenery and lots of shady trees. But water is also included, which contributes to cooling as well as infiltration areas that fit in with future rainwater management. Overall, the contribution to the Marx-Engels-Forum competition envisages a modern, climate-resilient urban space that enables a variety of uses.

Good things take time

The idea of initially creating a green space in the heart of old Berlin preserves opportunities for future generations. For the near future, the jury recommended that the first prize-winning work by RMP Lenzen be realized. This brings a controversial debate to an end. Hardly any other place in Berlin has experienced more planning and discussions than the Marx-Engels-Forum. But for the building senator, it is clear that the city of Berlin has done the right thing. After the fall of the Wall, it did not rush into planning. Now, against the backdrop of current plans for Alexanderplatz and Molkenmarkt and against the backdrop of climate adaptation and the mobility turnaround, things can be designed in peace.
