Between coal dust and high-tech: the emergence of an icon

Anyone talking about Schalke’s stadium cannot ignore its history. Gelsenkirchen, once synonymous with mining and mining culture, has made an architectural statement with the arena that radiates far beyond soccer. Even the choice of location was a signal: no longer in the middle of the city, but on the site of a former colliery, a stadium was created that does not conceal the industrial DNA of the region, but celebrates it. The architecture reflects this heritage without losing itself in it. Exposed concrete, steel girders and a clear, unpretentious design language characterize the image – not a glamorous temple, but a stadium that knows where it comes from.

Yet beneath the rough shell lies a technical marvel. Right from the start, the designers focused on innovation without betraying the myth. The movable pitch – a first in Europe – allows the pitch to be maintained outside the arena while concerts or trade fairs take place inside. The roof, which can be extended like a convertible, makes the stadium weather-independent and multifunctional. These solutions were ahead of their time and set the standard for modern arenas. The planners had to do pioneering work: statics, mechanics, materiality – everything was put to the test and rethought.

The implementation was a tour de force that could only succeed through close cooperation between all those involved. Architects, structural engineers, construction companies and technology suppliers all had to agree on a common goal: maximum flexibility with maximum robustness. The result is a stadium that is not only suitable for soccer, but for everything that inspires large crowds. Schalke thus became a role model – not only in terms of sport, but also architecturally. The arena shows how a sense of tradition and technical innovation can merge to create a new identity.

The social significance of this building extends far beyond the region. The stadium acts as a catalyst for urban development, attracts international events and is celebrated as a symbol of structural change. At the same time, it remains deeply rooted in the local fan culture – a balancing act that not many new buildings manage. This shows that architecture can create identity if it seeks a dialog between history and the future. Schalke’s stadium is not just any old multifunctional building, but an urban powerhouse that provokes and inspires architectural debate.

But the story is not over. Every modernization, every new usage trend raises questions: How do you stay relevant without degenerating into a soulless event hall? How do you integrate digital technologies without losing authenticity? Schalke’s stadium is a laboratory for these questions – and provides answers that go far beyond the soccer pitch.

Innovation in a concrete shell: technology, digitality and operation

Technical innovation is not an end in itself at Schalke Stadium, but part of a comprehensive utilization concept. The movable pitch was a sensation when it opened and is still a prime example of engineering in stadium construction today. The construction allows the sensitive turf to be moved outside on rails if necessary, where it is given optimum growing conditions. At the same time, the stadium can be used for events without the turf suffering – a technical balancing act that requires precise planning and sophisticated control. The structural design had to take into account variable loads, vibrations and extreme stresses – challenges that could only be solved with state-of-the-art simulation and interdisciplinary collaboration.

The arena’s roof system is another masterpiece. With its movable membrane and enormous span, it sets standards in terms of lightweight construction and flexibility. It has long been controlled digitally: sensors, automation and monitoring ensure that the roof functions reliably even in changing weather conditions. The integration of building management systems and digital control systems is not only a question of comfort, but also of operational safety and sustainability. Through targeted automation, energy consumption can be optimized, maintenance cycles extended and operating risks minimized – an aspect that is now standard in new stadium projects.

However, digitalization does not only play a role in the technical facilities. As early as the planning phase, Schalke relied on digital models and simulations to visualize and optimize complex processes. Today, such projects would hardly be conceivable without BIM (Building Information Modeling) and digital twins. During operation, smart systems enable the monitoring of energy flows, visitor flows and security aspects. Artificial intelligence is slowly making inroads, for example in the optimization of ticketing, catering and traffic management. The arena is therefore a testing ground for digital transformation in the construction industry – with all its opportunities and risks.

Visitors also benefit from digitalization. Modern access systems, intelligent routing and personalized services have long been a reality. Complex data analyses are running in the background to optimize the visitor experience and develop new business models. The focus here is on data protection and IT security – an area that is becoming increasingly important for operators and planners. The technical requirements are constantly growing: anyone planning or operating a stadium today needs expertise in networking, cyber security and system integration. Schalke shows how a stadium can become a digital ecosystem – a role model with imitation potential.

But where there is light, there is also shadow. The complexity of the systems brings new dependencies and challenges. Maintenance, updates, interoperability – all of this requires continuous training and close collaboration between architects, engineers, IT specialists and operators. The Schalke stadium makes it clear that architecture no longer ends at the façade. It reaches deep into digital and operational processes – anyone who doesn’t understand this is planning ahead of the market.

Sustainability and responsibility: between aspiration and reality

Modern stadium architecture is always caught between ecological responsibility and economic efficiency. Schalke’s stadium is no exception. Attention was already paid to resource-saving processes during construction: Recycled concrete, local materials, efficient construction processes. But the real challenges come during operation. A stadium of this size is an energy guzzler – heating, lighting, ventilation, technology and catering consume enormous amounts of electricity and water. If you want to implement sustainable solutions here, you need more than good intentions. Schalke relies on energy management, intelligent control and the use of renewable sources, such as photovoltaics and district heating.

Retrofitting and optimizing the technical systems is an ongoing project. LED lighting, heat recovery, water treatment – these are all building blocks on the way to a climate-friendly arena. But the devil is in the detail: the more complex the technology, the more difficult it is to control and maintain. Sustainable effects can only really be achieved with well thought-out system integration. Planners and operators alike are required to continuously evaluate, adjust and improve. Cooperation with energy suppliers, technology partners and science is essential.

Another sustainability issue is mobility. Thousands of visitors flock to the stadium on match days – mostly by car, often due to a lack of attractive alternatives. Schalke relies on cooperation with local public transport, optimized traffic management and digital information systems. Nevertheless, traffic congestion remains high – a problem shared by many stadiums. Integration into sustainable urban development concepts will become increasingly important in the future: multimodal connections, sharing models, electromobility. This shows that stadium architecture can no longer be an isolated solution, but must be embedded in the urban context.

However, sustainability does not only concern the environment, but also the social dimension. The stadium as a public space, as a meeting place for urban society – that is both an aspiration and an obligation. Schalke uses the arena for cultural events, trade fairs and social projects. The architecture must enable and promote this versatility. Flexible spatial concepts, accessibility, security – all these are components of sustainable stadium planning. The challenge: reconciling economic interests and the common good without slipping into arbitrariness or commercialization.

The result? The Schalke stadium is on its way, but not yet at its destination. Sustainability is a process, not a state. If you want to take the next step, you have to be prepared to leave the beaten track, integrate new technologies and constantly question your own role as an architect, engineer or operator. Schalke provides the blueprint for this – with corners, edges and a portion of Ruhrpott stubbornness.

Debate, criticism and vision: architecture at a crossroads

Every stadium construction is a political issue – this is just as true for Gelsenkirchen as it is for Zurich, Vienna or Basel. The discussions about identity, commercialization and authenticity are never-ending. Critics accuse modern arenas of becoming interchangeable event machines that sacrifice local characteristics in order to serve as many target groups as possible. Schalke’s stadium counters with a clear architectural signature and the conscious cultivation of regional traditions. But how much authenticity is still possible in the age of digital transformation? Where is the line between adaptation and arbitrariness?

Digitalization raises further questions. Who controls the data flows, who benefits from the new technologies? Operators, sponsors, visitors – or the architecture itself? The danger of the digital infrastructure becoming an end in itself is real. Transparency, data protection and open interfaces are not an optional extra, but a duty. Schalke has made progress here, but there is still a long way to go. The challenge lies in reconciling innovation and control – without losing sight of the users. New governance models are needed that bring architecture, technology and society together.

In an international comparison, Germany, Austria and Switzerland are in a good position, but not at the top. While mega arenas with even more radical digital and sustainability concepts are being built in England, Spain and the USA, the DACH countries rely on a balance of innovation and tradition. This has advantages: Integration into existing structures, involvement of local players, appreciation of building culture. But it also harbors risks: The danger of losing touch when global trends such as AI, the circular economy or smart infrastructure pick up speed.

The vision? Stadium architecture as a platform, as an open system for sport, culture, business and urban development. The arena as a digitally networked, sustainable meeting place – flexible, resilient, identity-creating. Schalke’s stadium is a step in this direction, but not the end point. The next generation of arenas will rely even more heavily on digitalization, participation and circular principles. Architecture will become a process, a service, an infrastructure. Those who understand this can help shape it. Those who remain stuck in the myth will become a footnote in history.

The debate remains lively. Between purism and pragmatism, between enthusiasm for technology and loyalty to tradition, between commerce and the common good. The Schalke stadium shows: Architecture can do more than just build – it can generate social dynamism, initiate discourse and help shape the future. Provided you have the courage to break new ground.

Conclusion: Schalke as a blueprint for the future of stadium architecture

The Schalke stadium is more than just a soccer temple. It is a lesson in the challenges and possibilities of modern architecture. Tradition and innovation meet here without blocking each other. The technical solutions are bold, the digital transformation is underway and sustainability remains a feat of strength. Any architect, engineer or operator planning a stadium today must be able to do far more than design beautiful facades. It’s about system integration, process control, social responsibility and future orientation. Schalke provides the template for this – not perfect, but inspiring. The stadium architecture of tomorrow will have to be measured against these standards. And that is a good thing.

Since architect Petra Kahlfeldt was appointed Berlin’s new Senate Building Director at the end of December 2021, criticism has been raining down from the German architecture scene. There is talk of a “victory for Berlin’s traditionalists” and that Petra Kahlfeldt’s previous commitment is in “stark contrast” to the current challenges facing Berlin. The debate brings together the opinions of two highly renowned German architects. An overview of the current situation – including Petra Kahlfeldt’s first public reactions – by Theresa Ramisch, editor-in-chief of G+L – Zeitschrift für Landschaftsarchitktur und Stadtplanung.

It has been clear since December 2021 that architect Petra Kahlfeldt will succeed Regula Lüscher and Hans Stimmann. Petra Kahlfeldt will become Senate Building Director in the Berlin Senate Department for Urban Development, Building and Housing under Senator Andreas Geisel. She thus helps to determine the cityscape and overall planning of Berlin. Regula Lüscher, who is Swiss, held the office of Senate Building Director for 14 years. She retired in July 2021. Berlin’s former building senator Sebastian Scheel kept the position vacant until after the parliamentary elections. Petra Kahlfeldt’s appointment is currently drawing a protest from the German architecture scene.

Petra Kahlfeldt (*1960 in Kaiserslautern) studied architecture in Berlin and Florence from 1979 to 1985. After studying architecture, she worked at the Berlin architecture firm Henning Pohle and also worked independently in an office partnership with her husband Paul Kahlfeldt from 1987 until her appointment as Senate Building Director in 2021. She was also a research assistant at the Chair of Design and Building Construction at TU Berlin from 1990 to 1995. From 2001 to 2003, she chaired the BDA Berlin. Between 2004 and 2009, she taught as Sutor Professor for Monument Conservation and Design at the Hochschule für Bildende Künste and at HafenCity University in Hamburg. Since 2004, she has been a professor in the teaching and research field of “Historical Building Constructions, Monument Conservation and Design” at the Hamburg University of Fine Arts, HafenCity Hamburg, the University of Bologna and the Berlin University of Applied Sciences. She is also a member of various advisory boards. More about Petra Kahlfeldt here.

Opponents describe the decision as an affront

In the run-up to the appointment, numerous renowned architects, academics and initiatives had already called for a transparent and open process for filling the position. 450 architects, initiatives and associations had signed an open letter “For an open and transparent selection of the new Senate Building Director”. On Monday, December 20, 2021, the SPD officially announced that Petra Kahlfeldt would take over the position of the new Senate Building Director. Since then, there have been numerous comments in various media about Petra Kahlfeldt’s appointment. One of the loudest voices is probably the initiative around HG Merz, Philipp Oswalt and Matthias Sauerbruch. On archplus.net, they published a text with the subtitle “Declaration of war on a social and ecological urban policy” in the wake of Petra Kahlfeldt’s appointment. In it, they describe the appointment without a selection process and public discussion as an “affront to the signatories” of the above-mentioned open letter.

Criticism of Petra Kahlfeldt: conservative and pro-privatization

According to the publication, Petra Kahlfeldt’s “previous job profile is in stark contrast to the current challenges facing Berlin”. Together with her husband, she has so far been “responsible for the realization of villas and luxury residential complexes in the upper price segment”. According to the report, Petra Kahlfeldt does not stand for “a city oriented towards the common good”, “sustainable, climate-friendly urban development” or “affordable housing construction oriented towards the common good”. It threatens to “relapse into the ideological trench warfare of an era in which key issues for the future were neglected for a long time”. She is “close to conservative circles that have campaigned for the reconstruction of the city according to historical patterns”. She has also “repeatedly advocated the privatization of public spaces”. Kahlfeldt is co-author of a Berlin position paper “in which a far-reaching privatization of public land in the center of Berlin is called for”. Petra Kahlfeldt had “also repeatedly reaffirmed this position in later speeches”. Therefore, “considerable conflicts in Berlin’s urban society” and building policy blockades are to be expected.

Withdrawal of the appeal demanded

The text was signed by the following planners:

Those involved are calling for the appointment of Petra Kahlfeldt as Senate Building Director to be withdrawn and for an open and transparent selection process to be carried out “that is appropriate to this important office and worthy of a capital city”. You can read the exact wording here.

Matthias Sauerbruch on Petra Kahlfeldt: “no experience with more complex participatory processes”

The initiative is not alone in its criticism. Architecture critic Nikolaus Bernau described the appointment of Petra Kahlfeldt in the Berliner Zeitung as a “victory for Berlin traditionalists”. He came to the conclusion that the “well-situated bourgeois architectural aesthetic a la Kahlfeldt & Kahlfeldt” could not cope with the current challenges facing Berlin.
In an interview with Die Welt, the renowned architect Matthias Sauerbruch said: “Petra Kahlfeldt is a colleague who has simply run an architecture firm, who has taught to a certain extent at various universities and has sat on a number of juries. She is a very friendly and communicative person, but has no experience with more complex participatory processes or administration at city or state level.”

Petra Kahlfeldt represents positions that run completely counter to the coalition agreement

The Association of German Architects Berlin in turn published a statement entitled “New appointment of the Senate Building Directorate lacking transparency and vision” in which it defines the new appointment “according to apparently party-political criteria” as a missed opportunity to fill the “office that is so important for the development of the city with the support of the professional public.”

In a guest article on freitag.de, Kristin Feireiss and Matthias Grünzig, who also signed the publication on archplus.net, also spoke out in more detail. Here they once again point out the missing examples of affordable housing and the planning of new urban quarters in Kahlfeldt’s portfolio. Furthermore, Petra Kahlfeldt has no experience in managing administrations. At the same time, she represents positions “that run completely counter to the coalition agreement”. As a member of the Stadtkern planning group founded in 2011, she has been advocating the privatization of public properties and areas for years.

Arno Lederer positions himself against Matthias Sauerbruch

In a guest article on welt.de, Arno Lederer, on the other hand, deliberately takes a stand against the criticism of Petra Kahlfeldt and also against some of his fellow architects. “This defamation harms all architects” is the title of his article. In it, he describes Petra Kahlfeldt as a “renowned and widely respected architect” and asks directly whether Matthias Sauerbruch’s statements about Petra Kahlfeldt are defamatory. The interview is peppered with half-truths and insinuations. According to Lederer, Matthias Sauerbruch’s statements left behind a “deliberately manipulative devaluation of the Senate Building Director”. He had even considered whether the interview with the “intelligent and thoroughly charming colleague Sauerbruch” was a fake. At the same time, he is harsh on the eight “esteemed” colleagues who are calling for the appointment to be withdrawn. They do not “even have the linguistic skill to formulate the accusations in a question to the future Senate Building Director”.

Lederer: BDA should call for constructive dialog

In his guest article, he also addresses the BDA and its members directly. He asks whether this is really the way they want to deal with each other. It is a public office that is at stake here, not an individual building. Mutual defamation in public created the image of an “already quarrelling bunch that – for this very reason – should not be taken into consideration”, said Lederer. The demands for a transparent selection process were justified. The open letter had shown that German architects could speak with one voice. What followed was shameful. The BDA would now be well advised to firstly stand up against the public defamation and secondly to call for constructive dialog on the other side.

Berlin architecture critics Zohlen and Haubrich back Petra Kahlfeldt

But Petra Kahlfeldt also received support from other quarters. Alongside Arno Lederer, Berlin architecture critic Gerwin Zohlen also accused the authors of the archplus publication of defaming Petra Kahlfeldt and her architectural oeuvre. In his article, journalist and architecture critic Rainer Haubrich also described the new Senate Building Director as “a good choice”. In turn, Berliner Zeitung publisher Holger Friedrich defined the new SenateBuildingDirector in a debate article entitled “Wenn Frauen bauen: Zum Start von Senatsbaudirektorin Petra Kahlfeldt“, defined the appointment of Petra Kahlfeldt as an “opportunity”. The uproar surrounding her appointment would confirm an opportunity for a new start. The Berlin group of Stadtbild e.V. also publicly welcomed the appointment. Its founder Peter Dobrink wrote in the Berliner Zeitung that Petra Kahlfeldt stands for creative openness, harmonious proportions and local traditions. And that is exactly what Berlin needs now.

In a nutshell: the criticism of Petra Kahlfeldt

To summarize, a total of eight German architects and planners – indirectly supported by the BDA Berlin – have publicly denied that the new Senate Building Director is competent for the position. They accuse her of having outdated views. According to the critics, these are contrary to the modern, sustainable urban design that is now needed in Berlin. Petra Kahlfeldt is accused of approving the privatization of public real estate and spaces in Berlin’s city centre. In the past, she and her architectural firm have primarily realized luxury buildings and villas and have therefore not acted in the interests of the common good. The critics also question whether Petra Kahlfeldt can and wants to promote participatory processes in the sense of a participation-oriented urban society.

Petra Kahlfeldt responds to criticism

What is Petra Kahlfeldt’s opinion on all this? She has since responded to the criticism in various interviews. G+L has also been able to talk to her. In it, she points out that the post of Senate Building Director is not only a professional position, but also a political one. This is often forgotten. She is also surprised that she has been criticized before she has even been able to make a substantive decision. And in an interview with Die Welt, she also discusses her urban development vision. “My guiding principle is the compact European city,” is the headline of the article. And Die Zeit quotes Kahlfeldt as saying: “There will be more high-rise buildings”. However, both articles are subject to a charge.

However, an interview with Petra Kahlfeldt is freely available on radioeins.de. Here she explains her job in general and that she sees herself as a bridge builder in her new position. When asked whether she has experience with a larger scale or the creation of affordable housing, Petra Kahlfeldt replies that her traditional professional focus is actually on conversion areas. These were sometimes larger urban quarters or individual buildings. Her traditional area, however, is the design and construction of existing buildings. Petra Kahlfeldt answers the question of whether Berlin Mitte needs more privatization instead of social housing in the negative. There is a good reason why Berlin has decided not to sell state-owned planning areas. When asked about her proximity to the Stadtkern planning group, Petra Kahlfeldt replies that the group is defined by its interdisciplinarity. This is also where instruments are discussed with urban planners that can be established contrary to speculation. You can listen to the whole interview here.

In an interview with G+L editor-in-chief Theresa Ramisch , the new Berlin Senate Building Director Petra Kahlfeldt comments on the accusations made against her.
