Real-world laboratories: from theory to urban experimental space
The term “real-world laboratory” is now on everyone’s lips – yet it remains a colorful label for many planners. What is behind it? Real-world laboratories originally come from science: they refer to experimental set-ups in which new solutions are tested under real conditions and with the participation of all relevant stakeholders. Unlike classic pilot projects, the real-world laboratory is not only geared towards a technical innovation, but also towards an open, iterative process. The city itself becomes a testing ground, everyday life a stage for experimentation.
The firstFirst - Der höchste Punkt des Dachs, an dem sich die beiden Giebel treffen. approaches to experimental urban planning date back to the 20th century, such as the famous Garden Cities or the car-friendly experimental districts of the post-war period. But today’s real-world laboratories are fundamentally different: they are participatory, transdisciplinary and deliberately temporary. Their goal is not the perfect end product, but learning together in the process. As a rule, various stakeholder groups – administration, science, business, civil society – are closely involved. This diversity makes the real-world laboratory a kind of “urban laboratory” in which hypotheses, prototypes and interventions are tested in real urban space.
In Germany, the instrument has become established at the latest with the “Real-world laboratories of sustainability” funding line. Cities such as Stuttgart, Munich and Hamburg use the format to test innovative transport or climate adaptation measures. The principle has also long been established in Switzerland and Austria, for example in the temporary redesign of streetscapes or the development of sustainable neighborhoods. The decisive factor is this: In the real-world laboratory, the focus is not on pure implementation, but on explorative research and the systematic evaluation of experiences.
This is no walk in the park for urban planners and landscape architects – because real-world laboratories require a change in thinking. They require openness to uncertainty, flexibility in process design and the willingness to accept mistakes as valuable data points. Instead of long planning cycles and rigid implementation, what counts is rapid prototyping, learning from setbacks and the ability to make course corrections together with all those involved. This makes real-world laboratories a prime example of truly adaptive urban development.
But despite all the euphoria, one thing remains crystal clear: real-world laboratories are not an end in themselves. Their success depends to a large extent on embedding them in strategic planning processes, on clear objectives and on professional process support. This is the only way to turn a one-off pilot project into a genuine learning effect for urban society – and temporary interventions into sustainable change.
Success factors and stumbling blocks: What experimental planning can really achieve
The fascination with real-world laboratories is based not least on their potential to break up established routines. Where traditional planning is often trapped in long approval processes and rigid regulations, experimental formats open up scope for action. However, this promise can only be fulfilled if certain success factors are taken into account – and typical pitfalls are avoided.
A key success factor is the clear definition of objectives. A real-world laboratory without a precise question runs the risk of getting lost in actionism. Successful examples show this: Good real-world laboratories are embedded in an overarching strategy, they have measurable objectives and a transparentTransparent: Transparent bezeichnet den Zustand von Materialien, die durchsichtig sind und das Durchdringen von Licht zulassen. Glas ist ein typisches Beispiel für transparente Materialien. evaluation concept. At the same time, they must remain open enough to allow for unexpected results. This balance between goal orientation and open-ended exploration is challenging – but indispensable.
Another key aspect is participation. Real-world laboratories are not circuses of experts, but rely on the participation of as many city dwellers as possible. This starts with early information and extends to genuine co-decision-making in the selection and design of the experiments. It is precisely citizen participation at eye level that distinguishes the real-world laboratory from classic top-down projects. However, participation must be professionally moderated – otherwise there is a risk of conflicts, misunderstandings or a slide into symbolic token participation.
Interdisciplinarity is also not just lip service. Anyone experimenting needs different perspectives – from transportation planning to social sciences and landscape architecture. This is the only way to recognize complex interactions and develop innovative solutions. What is important here is a sustainable governance model that clarifies competencies, decision-making paths and responsibilities. Without clear structures, many experiments fizzle out in informal networks or fail due to a lack of connectivity with the administration.
However, despite all the methodological finesse, classic stumbling blocks lurk: a lack of resources, unclear responsibilities, too short a timeframe or a lack of continuity jeopardize the transfer from experiment to regular operation. Legal uncertainties – for example regarding the approval of temporary measures – can also slow down the process. And last but not least, there is always the risk that real-world laboratories will be used by political actors merely as a fig leaf to delay or avoid real change.
Practical examples: How cities learn from urban experimentation
The practice of experimental urban planning is as colorful as the cities themselves. Anyone strolling through the Ottensen Open Streets real-world laboratory in Hamburg quickly realizes that this is not just about temporary seating or playful design – but about testing a new logic of public space. Cars out, people in, alternative forms of mobility and spontaneous uses. The accompanying research provides data on quality of stay, modal shift and acceptance. Even if not every component is adopted for permanent use, the learning effect for the administration and urban society remains enormous.
Another example: the “Stadt:Wandel” real-world laboratory in Mannheim, where sustainable neighborhood development, social inclusion and climate resilience go hand in hand. Here, not only was a temporary climate quarter designed, but the cooperation between science, city administration and residents was also intensively tested. The results – from new rainwater concepts to innovative participation formats – have an impact far beyond the neighborhood and provide blueprints for other cities.
In Zurich and Basel, real-world laboratories are used to test public spaces for new forms of mobility such as cargo bikes, e-scooters and pop-up bus lanes. The findings from temporary interventions are incorporated into long-term transport planning – and help to objectify political debates. Sometimes the results lead to permanent redesigns, sometimes to the deliberate abandonment of certain measures. The decisive factor is dealing openly with failure: What doesn’t work is seen as valuable information for the next planning step, not as a flaw.
But it is not only large cities that benefit. Smaller municipalities – such as Lustenau in Austria or Constance on Lake Constance – also use real-world laboratories to test the transformation of parking spaces into multifunctional open spaces, the integration of digital technologies or new forms of neighborly cooperation. New networks are often created between administration, associations and companies that continue to exist even after the experiment has ended.
What all successful examples have in common is that they do not use the living lab as a one-way instrument, but as an integral part of a learning planning culture. The experience gained from the experiment is systematically documented, reflected upon and fed into urban development policy. In this way, the temporary real-world laboratory becomes a permanent driver of innovation.
Between courage and risk: the role of governance, participation and error culture
No real-world laboratory in the world works without a certain courage to take risks. The unknown, the unfinished, the potential for failure is in the DNA of the format. But this is precisely where its strength lies: where traditional planning relies on planning certainty, the real-world laboratory allows innovations to be tested in a controlled manner under real conditions. The risk is not hidden, but actively managed – for example through iterative feedback loops, accompanying evaluation and the conscious involvement of all relevant stakeholders.
Governance remains a central challenge. Who bears responsibility? How are results fed back into administration and politics? Successful real-world laboratories work with clear mandates, transparentTransparent: Transparent bezeichnet den Zustand von Materialien, die durchsichtig sind und das Durchdringen von Licht zulassen. Glas ist ein typisches Beispiel für transparente Materialien. decision-making processes and an open error culture. Mistakes are not hushed up, but seen as learning opportunities. However, this also requires a certain tolerance for frustration and a willingness to change perspectives – qualities that are not always a given in the high-tech world of everyday planning.
Public participation is not a matter of course, but must be actively shaped. Good real-world laboratories rely on low-threshold communication channels, creative participation formats and continuous feedback. This requires resources, time and a willingness to listen to uncomfortable opinions. At the same time, expectations need to be managed – because not every idea tested in the real-world lab is later implemented. Transparency and clear communication are therefore essential.
The role of interdisciplinarity is particularly exciting. The more complex the challenges – from climate adaptation and digitalization to social integration – the more important it is for experts from different disciplines to work together. Real-world laboratories offer an ideal framework for this. They bring together planners, architects, social scientists, engineers, artists and many more. This not only creates innovative solutions, but also new forms of cooperation that are good for urban development in the long term.
But for all their advantages: Real-world laboratories are not a panacea. They can reinforce existing inequalities if they only provide access to certain groups. They can raise expectations that are not metMet: Met ist eine Maßeinheit für Länge, die vor allem in der Schiff- und Luftfahrt verwendet wird. Ein Met entspricht der Länge eines Strichs, der mithilfe eines Geodreiecks von der Kartenskala abgegriffen wird und auf der Karte eine Entfernung von 1852 Metern darstellt.. And they harbor the risk of being misused as a fig leaf for the lack of structural change. Therefore, without serious reflection, professional support and strategic embedding, the potential of the urban experiment remains untapped.
Outlook: Real-world laboratories as a future model for a learning city
What remains after the urban experiment? The answer is as simple as it is challenging: real-world laboratories are not a fad, but a future model for cities that want to learn. They open up spaces in which new things can be tried out, mistakes can be made and insights can be gained. They help to master the complexity of urban transformations by bringing together theory and practice, planning and everyday life, administration and urban society at eye level.
For urban planners, landscape architects and urbanists, this means that anyone who wants to shape change cannot avoid the real-world laboratory. It takes courage to leave the beaten track, accept uncertainties and explore new paths together with others. The city thus becomes a place of learning – and experimentation an integral part of the planning culture.
The future of urban development lies in the balance between experimentation and institutionalization. Real-world laboratories must not remain one-off actions, but must become part of an overall strategic development. Only then can they develop their full effect as a driver of innovation, participation tool and learning platform. This requires that results are systematically documented, disseminated and transferred to regular planning.
At the same time, a new culture of error is needed – one that sees failure as an opportunity and does not regard failure as a flaw, but as a necessary step on the way to a better solution. Cities that embrace this not only become more innovative, but also more resilient and adaptable.
Conclusion: Planning in the real-world laboratory is not an end in itself, but a key to the future viability of urban spaces. Those who boldly experiment today will shape the city of tomorrow – open, flexible and ready to learn. And that is nothing less than the urgently needed leap in quality for urban development in German-speaking countries.
In summary, it can be said: Real-world laboratories are far more than temporary playgrounds for creative city makers. They are the laboratory of a new planning culture that focuses on learning, participation and openness. By daring to use experimental formats, cities gain valuable insights for the design of resilient, liveable and sustainable urban spaces. The key is not to see the living lab as a one-off event, but as a driver for continuous change and innovation. Those who understand planning as a learning process turn every experiment into a building block for the city of tomorrow – and thus set standards that others will follow.
