Lego City: Who said urban planning had to be dull, slow and devoid of imagination? Welcome to the era in which architects and designers build cities like Lego – creatively, modularly, digitally. The only question is: are we ready to make the leap from gray theory to colorful practice?

Creative urban planning is experiencing a renaissance thanks to digital tools and modular approaches
Lego City is a symbol of flexible, innovative and participatory urbanism
Germany, Austria and Switzerland are experimenting with new urban building blocks – but often still too timidly
Digitalization and AI are revolutionizing design and participation, but are encountering structural resistance
Sustainability stands between aspiration and reality – circular construction meets old regulations
Technical expertise is becoming an entry ticket: data management, simulation and parametrics dominate
The architectural profession must reinvent itself: From lone wolves to urban system thinkers
Debates about standardization, commercialization and accessibility divide the professional world
Global role models show where the journey could lead – if the courage to rethink is there

Lego City as a metaphor: urban planning without borders – or just a beautiful dream?

Let’s imagine that the city really is a Lego model: building blocks that can be combined at will, modules that add new functions, streets that can be moved around as the mood takes you. A paradise for planners and designers, a nightmare for traditionalists. But the reality is different. In Germany, Austria and Switzerland, classic urban planning still dominates – cumbersome, rule-driven, with a fair amount of bureaucracy. The vision of Lego City often remains a nice gimmick that raises eyebrows in competitions and renderings, but is rarely actually put into practice.

Nevertheless, the first projects are focusing on modular district development, flexible usage concepts and participatory planning processes. In Zurich, the Hunziker Areal is celebrated as a showcase model, Vienna is experimenting with temporary structures and in Berlin, courageous building groups are venturing into unusual urban concepts. The building blocks are there – but there is often a lack of courage to actually take them out of the box. Fear of losing control, legal gray areas and the famous German thoroughness put the brakes on imagination. Anyone who builds too much that doesn’t fit into the grid risks endless approval processes and a wave of indignation from administrative circles.

But the Lego metaphor has a serious core. It stands for the idea that cities should not be seen as rigid structures, but as open systems. For architects and designers, this means that the design is never complete, but always part of a larger game. Today a residential module, tomorrow a cultural building block and the day after tomorrow perhaps a green infrastructure that blends in seamlessly. Understanding this dynamic gives you a whole new toolbox – and you have to learn how to use it.

The challenge is to combine the playful logic of Lego with the complex requirements of real urban development. Technical standards, legal frameworks and social expectations cannot simply be switched off. But they can at least be questioned. If you think of the city as a permanently changeable system, you can react more quickly to crises, test innovations and reorganize participation. This is not a gimmick, but a bitter necessity in the age of climate change, housing shortages and digital transformation.

In the end, Lego City is more than just a nice comparison. It is a call to leave your comfort zone and see the city as a field for experimentation. Those who fail to do so will be mercilessly overtaken in the next planning round – by those who have long understood that urbanity is never finished, but always under construction.

Digital tools: from construction kit to real-time city

Digitalization has the potential to catapult Lego logic out of the children’s corner and into the heart of urban planning. With building information modeling, parametric planning and urban digital twins, tools are now available that enable unprecedented flexibility. Cities become data landscapes, designs become living simulations, decision-making processes become iterative loops. It sounds like science fiction, but it has long since become reality – at least in places where people dare to use the new technologies consistently.

Germany, Austria and Switzerland? The change is noticeable here, but it is still a long way from being established. While metropolises such as Singapore or Helsinki control their city models in real time, German-speaking cities are mostly experimenting at pilot level. Hamburg, Vienna and Zurich show how digital twins can revolutionize planning – but the large-scale rollout remains the exception. There are many reasons for this: a lack of standards, fragmented responsibilities, data protection fears and a certain respect for one’s own innovative strength.

Nevertheless, the trend is unstoppable. Digital building blocks are replacing static master plan thinking with a dynamic process architecture. Anyone planning a neighborhood today simulates traffic, energy, climate and social interaction in a digital image of the city. AI algorithms analyse usage patterns, suggest alternative scenarios and optimize land use in real time. Architecture is becoming a data craft, design an experiment in a digital wind tunnel.

But the brave new world has its downsides. Those who do not master the digital toolbox quickly lose touch. Technical expertise is becoming a basic requirement, data management and interoperability a question of survival. And the question of power remains unresolved: Who controls the algorithms, who decides on the data flows, who guarantees transparency? The danger of commercialization is great – open city models quickly become proprietary platforms, participatory planning becomes algorithmic bias.

For architects and designers, this means that further training is mandatory, not optional. Those who embrace the new tools can help shape the city of tomorrow – but only if they are prepared to throw old certainties overboard. Lego logic is no longer a gimmick, but the key to future urbanism. Anyone who ignores it is planning past reality.

Sustainability meets modular construction: between green utopia and regulatory reality

The longing for the perfect, sustainable city is as old as urbanism itself. Lego City as a circular, resource-conserving and socially just utopia sounds tempting – but the road to it is rocky. In Germany, Austria and Switzerland, linear construction still dominates: Demolish, rebuild, demolish again. Recycling rates are sobering, modular systems have a niche existence and the circular economy often remains lip service.

But there are glimmers of hope. More and more projects are focusing on reusable components, flexible building structures and resource-saving materials. In Vienna, temporary school modules are being built that can be moved and reassembled as required. In Zurich, wooden construction kits are being tested for urban redensification. And in Berlin, old buildings are being extended with prefabricated elements instead of being demolished. Lego logic is becoming a blueprint for circular construction – at least on a small scale.

The problem is that the regulatory framework is lagging behind. Building regulations, standards and funding programs are designed for durability and stability, not for flexibility and change. Anyone who wants to erect a modular building struggles with fire safety regulations, usage rights and an administration that sees innovation as a risk rather than an opportunity. As a result, many projects fail due to bureaucracy before they can even get off the ground.

Digitalization could become a game changer here. Precise data, simulations and digital product passports can be used to track the service life of components, plan reuse and document compliance with sustainability targets. AI systems can optimize material flows, analyse life cycle costs and minimize the ecological footprint. But here too, without political and social rethinking, the Lego city will remain a beautiful dream.

For experts, this means that sustainability is not an add-on, but the touchstone for real innovation. Anyone who is serious about the Lego logic must be prepared to cut away old habits and forge new alliances – between planning, technology and administration. This is the only way to turn the green utopia into everyday urban life.

Participation, debate, disruption: who is actually building the Lego city?

Lego City thrives on the idea that everyone can help build it. But in reality, participation often falls by the wayside. Urban development is still the domain of experts, authorities and investors – at most, citizens are given a friendly hearing at information events. The result: mistrust, conflicts and projects that are not planned to meet needs. Lego logic calls for a radical rethink: urban planning as an open process in which all stakeholders are involved – digitally, transparently and iteratively.

Digital tools offer completely new possibilities here. Participation platforms, visualization tools and collaborative design environments make it possible to involve citizens at an early stage, simulate alternatives and make decisions comprehensible. In Zurich, for example, neighborhood developments are designed together in digital workshops. In Vienna, users can influence traffic simulations live. And in Berlin, building groups are testing new participation formats that turn traditional planning procedures on their head.

But the debate is heated. Critics warn of participants being overburdened, a flattening of professionalism and a commercialization of participation. Opening up the Lego city to everyone risks chaos, delays and endless discussions. The experts are divided: While some see openness as the future, others fear a loss of control and the end of traditional expertise.

One thing is certain: Participation is not an end in itself, but a balancing act between inclusion and quality. Digital tools can help to master complexity – but only if they are transparent, open and accessible. Anyone who sees urban planning as a Lego project must be prepared to share responsibility, admit mistakes and learn from them. This is uncomfortable, but there is no alternative at a time when cities are more complex, dynamic and diverse than ever.

At the end of the day, the realization is that the Lego city is not a sure-fire success. It calls for a new planning culture based on dialog, experimentation and openness. Those who dare to do so can reinvent urbanism – and finally make the leap from gray theory to colorful practice.

Global discourses and local realities: Who dares to think Lego?

In international comparison, the German-speaking countries often seem like onlookers: impressed by the experiments in Asia, Scandinavia or North America, but still too hesitant themselves to really dare to try something new. Singapore is building digital test laboratories for entire city districts, Helsinki is simulating urban processes in real time and Copenhagen is focusing on radical modularity in urban development. Lego logic has long been part of everyday life there – because it is seen as the answer to the challenges of the present.

In Germany, the focus is on looking back: on tried and tested processes, historical cityscapes and a planning culture that sees change as a risk rather than an opportunity. As a result, many good ideas fizzle out in pilot projects that never make the leap into the mainstream. The fear of loss of control, mistakes and public criticism paralyzes the courage to change. Yet now would be the right time to question our own path dependencies and break new ground.

The international architecture and urbanism scene has long been discussing the future of modular cities, open data platforms and AI-controlled planning. Competitions, research projects and start-up initiatives are constantly providing new impetus – whether parametric neighborhood development, circular material flows or participatory governance models. If you want to have a say here, you have to be prepared to take Lego logic seriously and dare to experiment.

This requires more than just technical expertise. It requires a new attitude: openness to mistakes, a desire to collaborate and the courage to constantly question your own expertise. The next generation of architects, planners and designers will no longer work on the drawing board, but on the digital construction kit – networked, agile and eager to experiment. Those who ignore this will remain spectators in a game whose rules have long since been rewritten.

So the question is not whether the Lego city is possible – but who dares to build it. The time for excuses is over. Anyone who doesn’t take the plunge into the unknown now will be overrun by the future. The building blocks are ready – it’s time to put them together.

Conclusion: Lego City is more than just a game – it is the laboratory of the future

Lego City stands for a new urbanism that focuses on creativity, flexibility and participation. Between digital simulation, sustainable modular construction and radical openness, a new understanding of the city is emerging – as an open system that is constantly changing. Germany, Austria and Switzerland are on the way, but are often too cautious, too bureaucratic and too reluctant to experiment. Anyone who takes Lego logic seriously must be prepared to question old habits, develop technical expertise and think radically about participation. The future of the city lies in the construction kit – and those who don’t build now will remain spectators. The revolution has long since begun. Welcome to the laboratory of the urban future.

Architecture Biennale 2021: In the Austrian Pavilion

Building design

Editor-in-chief Fabian Peters takes you to the 2021 Architecture Biennale in Venice.

Editor-in-chief Fabian Peters is currently in Venice. He is taking you on a tour of the pavilions, like here in the Austrian Pavilion.

In their project, the two curators of the Austrian pavilion, Peter Mörtenböck and Helge Mooshammer, examine the manifestations and effects of platform urbanism. As part of their research, they have ultimately identified and categorized the physical manifestations of the digital and platform industry that are typical of the times with great precision. To present their findings, Mörtenböck and Mooshammer chose different forms of presentation – both artistic and more documentary. The artistic approaches to the topic include the two slogans that greet visitors at the entrance to the two wings of the pavilion: “Access is the new capital” and “The platform is my boyfriend“.

An installation of stools has already been set up in front of the pavilion, allowing the words “we like” to be read from a distance and in an extremely “instagrammable” way. The stools are the kind of DIY furniture that can be found in countless internet companies today – especially those that have long since outgrown start-up status. Dozens of examples of such contemporary phenomena are depicted on two walls of the pavilion in the form of patent drawings – from the Corporate Campus and the Co-Working Headphones to the Food Truck and the Vertical Forest to the Corporate Bus and the Pop-up Container Market. They leave the interpretation of their findings to the visitors, who can stretch out on the pavilion terrace on the currently ubiquitous outdoor lounge furniture.

A major Dix exhibition is currently running in Colmar. It focuses on the reception of the Isenheim Age by the German artist. A highlight of the show has been restored for the occasion. An insight.

The Unterlinden Museum in Colmar, Alsace, has been showing the major special exhibition “Otto Dix – Isenheim Altarpiece” since the beginning of October and explores the extent to which Otto Dix’s work was influenced by Matthias Grünewald’s Isenheim Altarpiece. At the same time, the museum is also honoring the 125th anniversary of the artist’s birth and the 500th anniversary of the mural altar, the museum’s main attraction, which is on permanent display there.

“I saw the Isenheim Altarpiece twice, an enormous work of unheard-of boldness and freedom beyond all composition or construction and inexplicably mysterious in its contexts,” wrote Otto Dix to his wife Martha on September 9, 1945. This letter can be seen with more than 100 works by the painter at the Museum Unterlinden. Paintings, drawings, prints and archive material from all over the world, including loans from major public collections such as the Musée national d’art moderne in Paris, the MoMA in New York and the Vatican Museums.

The Isenheim Altarpiece, created by Matthias Grünewald in the 16th century, has inspired many artists such as Böcklin, Klee, Baselitz and Picasso since its rediscovery in the late 19th century. However, Dix referred to the Isenheim Altarpiece throughout his work, emphasizes curator Frédérique Goerig-Hergott.

Restored highlight

One of the highlights of the exhibition is the triptych “Madonna in front of barbed wire” from the Maria Frieden church in Berlin-Mariendorf, which is rarely lent out and has been restored by the museum’s conservators. It is the last triptych painted by Dix in 1945 and was intended for the Catholic chapel of the prison camp where Dix was sent shortly before the end of the Second World War. It shows the Virgin and Child as well as St. Paul and St. Peter in front of a crowd of prisoners of war and a landscape of houses destroyed by the war. “The most important part of the restoration was to check the adhesion of the paint layer and to locate any areas at risk of flaking. We also carried out a light cleaning of the paint layer, which meant minimal intervention in the paint substance,” explains restorer Carole Juillet. The wooden panels are in excellent condition and have been primed with gesso to prevent the wood from warping.

Examination of the painting revealed three different overpaintings. The oldest overpainting can be found in the area of the sky and the clouds in the middle panel. The overpaintings on the panel with St. Peter in the area of his cloak and in the area of Mary’s dress could be by Dix himself. The technique in oil/tempera is similar to that of the entire triptych. Juillet continues: “We have benefited greatly from this loan, as it is always interesting to be able to study an artist’s painting technique at close quarters and thus contribute a piece of the mosaic to Otto Dix research.”

Interested parties can view the restored painting with its overpaintings and its reference to Grünewald in the exhibition “Otto Dix – Isenheim Altarpiece” until January 30, 2017.
