Right to the city versus claim to space: the new measurement of urban conflicts

The city is not a static entity, but a permanent negotiation of uses, interests, power and participation. The famous “right to the city”, a concept coined by French sociologist Henri Lefebvre back in 1968, is currently experiencing a renaissance – not least because competition for space in urban areas is escalating. Conflicts are coming to a head in German, Austrian and Swiss cities: living space is becoming scarce, businesses are competing with open space, logistics are demanding space, while movements such as Fridays for Future and initiatives for common goods are claiming space with publicity. The open question: who decides how urban space is used – and by what right?

In theory, the right to the city is a right of all city dwellers to actively participate in urban life and the shaping of the city. This goes far beyond a subjective right to housing and – according to Lefebvre – includes the power to help shape one’s own living environment, to use open spaces and to be involved in political processes. In everyday life, however, there are powerful opponents to this claim: Property rights, land use plans, investor interests, legal requirements of spatial planning and, last but not least, economic constraints. This creates a highly dynamic field of tension that poses fundamental challenges for urban planning.

These conflict zones are by no means abstract. They manifest themselves daily in debates about redensification, interim use, gentrification, expropriation, land recycling and climate adaptation. The political and legal instruments, such as the Building Code in Germany, the Spatial Planning Act in Switzerland or Austrian spatial planning, are designed to control land and safeguard the common good. But how resilient are these instruments when social change, digitalization and new forms of protest shift the parameters?

Planners are caught in the crossfire: they are supposed to secure and densify open spaces, prevent land speculation and enable innovation, involve citizens and attract investors. Conventional methods are reaching their limits. This is particularly evident on the outskirts of metropolitan areas, where land for housing, energy, nature conservation and commerce is competing – and protests such as those in Berlin, Munich and Zurich show that acceptance of traditional planning is dwindling. The question is no longer whether conflicts arise, but how productively they can be managed.

The discussion about the right to the city has thus become the key issue in contemporary spatial planning. It forces us to understand planning not as a technocratic act, but as a social process that focuses on negotiation, participation and conflict management. Those who ignore this change risk not only escalating protests, but also the loss of urban quality of life and innovative strength.

Legal foundations and social dynamics: What the right to the city really means

The right to the city is not a fixed law, but a normative claim that is fed by various legal, social and political sources. In Germany, Austria and Switzerland, there is no constitutional guarantee of urban participation, but numerous pieces of legislation – from the Basic Law to the Building Code and municipal regulations – define participation, ownership and the common good as central principles. The so-called “planning discretion” is particularly relevant: on the one hand, municipalities have the task of distributing land fairly and safeguarding the common good, while on the other hand they must take into account private property rights, economic freedom and investment protection.

The social dynamics of the right to the city are closely linked to processes such as urbanization, migration, social segregation and digitalization. Large cities are melting pots of different lifestyles and interests. The right to the city is demanded by initiatives, movements and urban actors who oppose displacement, rising rents, privatization of public spaces and a lack of co-determination. This often leads to legal disputes: for example, when citizens’ groups take legal action against development plans, interim users fight for temporary access to space or expropriation is discussed as a means of combating land speculation.

The legal instruments for controlling competition for land are diverse. The German Building Code, for example, calls for “sustainable urban development” that “reconciles social, economic and environmental requirements”. However, the interpretation of these requirements is often controversial. Who decides when the common good takes precedence and when private interests prevail? Case law tends to value property rights highly, but the Federal Constitutional Court has repeatedly emphasized that property also carries social obligations.

In Switzerland and Austria, the situation is similarly complex. Although there are extensive regulations on spatial planning and participation, dealing with competition for land remains a permanent process of negotiation. The instruments of land reallocation, expropriation, securing open spaces and regional planning are particularly controversial. In the end, it is often the political majority that decides – and increasingly also public pressure from protests and social media.

The social dimension of the right to the city is also reflected in digitalization: new technologies such as urban digital twins, open data and participation platforms open up opportunities to make conflicts more transparent and inclusive. However, they also harbour risks – for example, if they lead to the commercialization of data or algorithmic distortion of urban decision-making processes. The right to the city therefore remains a dynamic, contested concept that challenges planning, law and society in equal measure.

Conflicts over space in everyday urban life: examples, escalations and lessons learned

The collision between the right to the city and the right to space is no longer a theoretical debate, but a lived urban reality. Numerous examples from German-speaking countries illustrate how these conflicts are played out in practice – often with a high level of media attention, sometimes with surprising twists and turns and occasionally with innovative solutions. The fight for the Dragonerareal in Berlin, the occupation of the Kochareal in Zurich and the protests around the Nordbahnhofviertel in Vienna are exemplary of a new generation of land conflicts.

In the case of the Dragonerareal in Berlin-Kreuzberg, the interests of investors, the city administration, politicians and residents clashed for years. While the landowner focused on maximum utilization, citizens’ initiatives and local groups demanded a development oriented towards the common good. After a long struggle – and a spectacular reversal of the land sale – the state of Berlin decided to secure the site for affordable housing and social infrastructure. The key to the compromise lay in political mobilization, the legal enforcement of pre-emptive rights and a transparent culture of participation.

Another example is provided by Zurich, where the former Kochareal was temporarily used by collectives for years. The city was faced with a choice: eviction in favor of the owners or integration of the interim users into long-term development plans. After intensive negotiations, a model emerged that secured both temporary use and future development and open space – a model case of constructive conflict resolution, albeit not without friction and setbacks.

In Vienna, the Nordbahnhof district became a laboratory for participatory urban development. Areas that were previously used for industrial purposes were to be redeveloped. Citizen participation, urban planning competitions and social compatibility were emphasized from the outset. Nevertheless, it became clear that demands clashed here too – for example, when green spaces were to be sacrificed for housing or when the social mix failed due to financial realities.

These cases show: Land conflicts cannot be resolved by technocratic planning or legal instruments alone. It takes dialog, transparency, political determination and sometimes also the recognition that not all demands can be fully satisfied. The most important lesson: successful urban development occurs where conflicts are managed productively – not where they are suppressed or made taboo.

Tools and strategies for the future: conflict management and innovation in spatial planning

If you want to master conflict zones in spatial planning, you need modern tools – and above all the courage to break new ground. Traditional tools such as land use plans, development plans, pre-emption rights, urban development contracts, reallocations and expropriations remain indispensable, but are increasingly reaching their limits. The highly dynamic nature of urban developments, the growing influence of civil society players and the complexity of multiple usage requirements in particular call for more flexible, dialog-oriented approaches.

A key success factor is the early and transparent participation of all relevant groups. Traditional citizen participation is often no longer sufficient. Digital tools such as urban digital twins, participatory online platforms, visualizations and real-time data can make complex issues easier to understand and enable new forms of co-design. Scenarios can be simulated, the effects of planning made visible and alternatives jointly evaluated. However, this requires data to be openly accessible, comprehensibly processed and not become a pawn in the hands of commercial interests.

Another field is innovative models of cooperative urban development: from cooperatives and heritable building rights to new alliances between the public sector, civil society and business. Projects such as the Viennese model of “soft urban renewal” or the conceptual allocation of land in Hamburg and Munich show that a focus on the common good, social mixing and sustainable use need not remain wishful thinking – as long as all sides are prepared to share responsibility and accept compromises.

The legal level is also evolving. New forms of land policy geared towards the common good, the further development of the building code, the strengthening of pre-emption rights and the fight against land speculation are perennial political issues. In Austria and Switzerland, innovative approaches such as land pools, vacancy registers and regional development corridors are also being discussed. It remains important that legal innovations are not suffocated by bureaucracy, but serve as a framework for social negotiation.

Ultimately, planners, administrators and politicians are faced with the task of not avoiding conflict, but rather understanding it as a driver for innovation and social progress. The city of the future will not be free of conflict – but it can deal with its contradictions in a resilient, fair and creative way. Those who rise to this challenge will not only shape space, but also the urban coexistence of tomorrow.

Conclusion: The productive power of urban conflicts – and what planners can learn from them

Conflict zones in spatial planning are not a dead end, but the driving force behind lively, future-oriented urban development. The right to the city and the right to space are not opposites, but two sides of the same coin: they describe the permanent process of understanding the city as a common good, a living space and a laboratory for innovation. Practice shows that conflicts over space can be resolved neither through authoritarian planning nor through complete deregulation. Instead, an intelligent mix of legal instruments, participatory processes, technical innovation and political will is required.

For planners, administrators and politicians, this means that they must learn to anticipate conflicts, make them transparent and negotiate them productively. They need the courage to share power and responsibility, forge new alliances and use the digital transformation for greater participation and transparency. This is the only way to secure the city as a space for the common good and diversity. The future of spatial planning does not lie in avoiding conflicts, but in using them creatively – as a source of innovation, justice and urban quality of life. Those who follow this path will turn urban areas of tension into the building blocks of a resilient, open and liveable city.
