Andreas Rosenkranz, a master stonemason and stone sculptor from Cologne, has developed Germany's first QR code gravestones.

Andreas Rosenkranz, a master stonemason and stone sculptor from Cologne, has developed Germany’s first QR-code gravestones and believes that anyone who denies the digital mourning aspect of today’s cemeteries has failed to recognize the changes in society.

How much change do German cemeteries need, and how much courage and willingness to change should cemetery administrations demonstrate? Finding comprehensive answers to these questions seems difficult. But one thing is clear: the industry has been grappling with them for over a decade now. In other countries, even longer: “In Sweden, as early as 1999, a deceased person received a headstone with a URL engraved on it that led to a memorial website. And since 2008, QR codes have been placed on gravestones in Japan,” says Andreas Rosenkranz. In Germany, however, widespread mobile internet access is still largely uncharted territory. To the master stonemason, the news from Japan therefore seems rather bizarre.

Just three years later, his son asks for an iPod instead of a Nintendo. Rosenkranz inspects it and finds among the pre-installed apps: a QR reader. The news from Japan comes back to his mind, and he’s certain that very soon, a great many Germans will be carrying a mobile device in their pockets. So he heads to his workshop, begins sketching, and develops a sandblasting technique to engrave QR codes deep into the natural stone. The result: the prototype of Germany’s first QR gravestone, which allows visitors to access more information about the deceased directly at the cemetery via their smartphones.

However, it’s more visually appealing than its Japanese counterparts. Rosenkranz believes the idea urgently needed an aesthetic overhaul: “Those plaques in Japan struck me as odd—they had a sort of price-tag look to them. Added to that are the German cemetery regulations, with their numerous restrictions, which the QR gravestones had to comply with.” The roughly 100 gravestones that Rosenkranz has since erected across Germany are therefore different: The QR code is handcrafted and carved in relief directly into the STEIN, integrated into the overall design of the gravestone. It’s far more beautiful than any sticker. In essence: a counterpart to the traditional gravestone inscription. “It was precisely in this capacity that the QR code was classified a year later by the German Association of Cities in a recommendation for action. They unexpectedly passed me on the right without signaling by equating the QR code with a gravestone inscription,” says Rosenkranz. As, to quote from the recommendation, “an independent or unifying design element that cemetery administrations cannot prohibit.”

Since 2011, the master stonemason has been generating QR codes from a triple-domain that redirect to the respective pages set up by family members. “This gives us a short, concise code that, for example, can be partially covered—say, by a quarter—if it looks better design-wise, or remain readable even when weathered.”

The first gravestone that Rosenkranz erected in 2012, featuring a cross-shaped QR code, was followed by other ideas such as the QR stele, the QR base stone, and QR code inlays. These can be incorporated into existing gravestones. This is because Rosenkranz not only wants to combine modern technology with memorial design, but—like many of his colleagues in the past—often faces a space constraint: “Anyone standing in front of one of those small urn graves can understand this: Where exactly is there supposed to be room for a STEIN that provides personalized information about the deceased?”

Rosenkranz is tired of the limited “business card” approach, especially in an age when there is an infinite amount of space available in the virtual realm. For relatives, the QR code also sometimes takes the pressure off of having to know exactly, shortly after a death, what the headstone should look like and what it should say about the deceased. “For example, some initially link to the obituary online, which most newspapers now offer as part of a package with traditional obituaries. After a year, they might then redirect to a custom-designed memorial page or the deceased’s Facebook profile.”

Digital mourning has become established, and Rosenkranz combines it with remembrance at the cemetery. This gives family members the opportunity to play a greater role in shaping their grief—and to express how their grief changes over time. Rosenkranz does not believe that the internet is taking over the grieving process. In fact, it’s not as if this Rhinelander—with his friendly dialect and full beard—has anything against traditions as such. He generally considers the requirement to hold a cemetery service, for example, to be a good approach, because: “No one is just a private individual; everyone is also part of society. In the past, everyone was at the cemetery, and there they were all the same—namely, dead. With privatized funerals, that is lost; a kind of anonymization of society sets in, because many people disappear from public memory along with their death.”

And Rosenkranz himself? He doesn’t think too much about his own death. But since it takes nine months to come into the world, a burial seems like a good choice to him. But: “Ultimately, that’s up to my loved ones, because planning a funeral is a very healing process of mourning.”

About the person:Andreas Rosenkranz, 55, completed his stonemasonry apprenticeship in the 1980s, specializing in restoration. With a scholarship from the European Community, he later went to England and worked, among other places, at Westminster Abbey. In 1990, he earned his master craftsman’s certificate in Düsseldorf. His masterpiece is a Japanese-style stele made of basalt lava. Afterward, he worked as a freelance sculptor, creating figures for Cologne’s Ratsturm. In 1993, Rosenkranz founded his own business. At first, he mainly produced kitchen countertops; later, he took on restoration projects as well. Today, he employs one full-time staff member and brings in freelancers as needed. He works in the fields of historic preservation, interior design, memorial design, and sculpture. Then as now, for him, the appeal of the craft lies in the creative process—and in “losing oneself contemplatively in the work.”

Holography as a design medium – the end of the screen? Anyone who still believes that the future of architecture will be played out in 2D on monitors and tablets has either read too little science fiction or simply missed out on the innovation spurts of recent years. Holography is preparing to dethrone the screen as the central design tool. Why this is more than just a technical gimmick and what revolution is actually rolling towards us – we explain here with a sharp pen, a cool head and plenty of insider knowledge.

  • Holography offers a radical new dimension to the architectural design process – beyond the mouse and display.
  • Germany, Austria and Switzerland are at the forefront of technology, but are hesitant to use it across the board.
  • Digital planning, AI and holography are increasingly merging to create new working methods.
  • Sustainability benefits from more immersive, less error-prone design processes – at least in theory.
  • Technical expertise is changing rapidly – from CAD operator to spatial designer.
  • The architectural profession is facing fundamental changes in training and practice.
  • Debates about costs, accessibility, data security and the sense or nonsense of holography are dividing the industry.
  • Global trends are putting pressure on the DACH region – Asia, North America and parts of Scandinavia are setting the pace.

Holography: from trade fair toy to design medium with explosive power

Holography has had an amazing career in architecture – from a dusty gimmick at technology trade fairs to a serious design medium. The screen, for decades the gateway to the digital world, is now facing stiff competition. Where renderings and 3D models used to be presented in flat format, today the building floats in the middle of the room as a holographic image. What sounds like a marketing gimmick has established itself as a real tool in research institutes, large planning offices and increasingly also in local authority building departments. The advantages are obvious: immersion, spatial perception and interactivity achieve a quality that a monitor simply cannot offer. Suddenly the design becomes accessible, construction errors can literally be walked around, and even laypeople can intuitively grasp complex relationships. It is no longer a secret that holography has disruptive potential in this area. But the industry is skeptical. The investment costs are high, the training requirements should not be underestimated and many companies lack the necessary infrastructure. However, the first to take the plunge are reporting considerable efficiency gains – not to mention the wow effect for customers. Those still clinging to the screen today may be museum-ready tomorrow.

In Germany, Austria and Switzerland in particular, technology is viewed with typical Central European reserve. The innovative spirit of tech start-ups meets the reservations of the planning bureaucracy. While entire districts have long been developed holographically in Singapore, here in Germany it is usually only enough for pilot projects and innovation labs. But the pressure is growing. The requirements for flexibility, precision and comprehensibility of designs are increasing rapidly – not least because developers and investors have long been accustomed to different standards internationally. If you don’t keep up, you lose.

The technology itself is also no longer what it was five years ago. Advances in projection, tracking and cloud-based data processing make holography suitable for everyday use. Integration with BIM and GIS systems is within reach, and AI-supported algorithms are helping to generate meaningful, visualizable models from mountains of data. What remains is the question of mindset: are architects and engineers ready to rethink their craft? The screen has long been the lowest common denominator – holography calls for more courage, more openness and, yes, more experimentation.

The vision: collaborative design processes in which teams in different cities, even on different continents, work on the same hologram. Misunderstandings and communication breakdowns, which are unavoidable in traditional meetings, could be a thing of the past. Holography sets new standards for participation, transparency and efficiency. However, as is so often the case in the construction industry, there is an ocean of regulations, fear of losing control and quite banal budget constraints between vision and everyday life.

Anyone wondering why the breakthrough is just around the corner will find the answer in the technological leaps of recent years. Hardware is cheaper, software is more powerful and user skepticism is fading – at least slowly. The screen has had its day, say some. The screen is here to stay, counter the others. As is so often the case, the truth lies somewhere in between. One thing is certain: Those who don’t move will be overrun by the hologram wave.

Digitalization, AI and holography – the new triumvirate of design planning

If digitalization and artificial intelligence have already shaken up architecture, then holography is the next logical step. It is not an isolated gadget, but the link between data and perception. Its great strength lies in the fusion of digital precision and spatial experience. While classic visualizations still end at the edge of the screen, the hologram opens up a new space for ideas and decisions. AI ensures that relevant, comprehensible models are created from billions of data records, while holography makes these models tangible for everyone involved. This not only changes the workflow, but also the roles in the design process. The planner becomes a curator who no longer just designs, but orchestrates – between algorithms, material reality and human intuition.

In practice, it looks like this: A BIM model is evaluated by AI, errors and optimization potential are automatically marked, and the result appears as a holographic image in the meeting room. Changes can be made in real time and immediately checked spatially. This not only saves time and money, but also minimizes the risk of planning errors, which traditionally only become apparent on the construction site – with all the familiar consequences. Holography is not an end in itself, but a response to the increasing complexity of construction tasks. It makes the invisible visible and the complex understandable.

Collaboration also benefits enormously. Multidisciplinary teams, which previously often planned at cross purposes, find a common denominator in the hologram. The model becomes a communication platform – intuitive, interactive and unambiguous. The digital transformation of the construction industry is thus reaching a new level. It is forcing everyone involved to leave their comfort zones and embrace new processes. Those who fail to do so will soon only be working for the rearguard of the industry – the future will be elsewhere.

However, as always, so much euphoria should be treated with caution. The flip side of the coin: if you lose control of the data, you also lose control of the design. Dependence on software providers, cloud services and proprietary formats is growing. Data protection, data sovereignty and cybersecurity are becoming key challenges. Open, collaborative planning in the hologram is not a sure-fire success – it must be actively designed and protected. Otherwise, the beautiful appearance could quickly become a trap.

The debate about the sense and nonsense of holography divides the industry. Some see it as a tool for vanity and showmanship, while others see it as the key to urgently needed modernization. Both sides are right – at least a little. The decisive factor is how the technology is used: as a show effect for render porn or as a serious working tool. The answer lies in practice. Those who create real added value will prevail. Those who merely dazzle will fall by the wayside.

Sustainability and holography – hope or hot air?

A popular myth: holography makes planning more sustainable because errors are detected earlier and resources are used more efficiently. Sounds convincing, but is only half the truth. Yes, immersive access to designs helps to uncover planning weaknesses before they mutate into expensive building damage. Simulations of daylight, energy flows or material cycles can be presented clearly and comprehensibly in the hologram. This leads to better decisions and ideally reduces the ecological footprint of a project. But the reality is more complex. The technology itself is resource-intensive – from hardware production to the power consumption of the server farms that calculate the data for the holograms.

In Germany, Austria and Switzerland, the issue of sustainability is viewed particularly critically. Subsidies are only granted if the ecological added value can be proven. This forces providers and users to take a closer look: How much energy does a hologram consume compared to a classic monitor? How can holography systems be integrated into sustainable planning processes? Anyone who cannot answer these questions will have a difficult time in German-speaking countries. At the same time, however, new opportunities are opening up: Participatory planning, transparent decision-making processes and the early involvement of stakeholders can help to find more sustainable solutions – provided that holography is used wisely.

So the big sustainability question remains: how can we manage the balancing act between technological progress and environmental compatibility? The answer is anything but trivial. New standards, clear guidelines and, above all, an awareness of the side effects of digitalization are needed. The industry must learn to think not only in terms of effects, but also in terms of life cycles. Holography is not a panacea, but it can become a building block for more sustainable planning – if it is part of a holistic concept.

Another aspect is that the democratization of planning through holography could lead to greater acceptance of sustainable projects. Those who understand what is being built and why are more willing to make compromises. Holography makes complex relationships visible and understandable – an opportunity that traditional presentations rarely offer. But here too, without transparency and open communication, the technology remains a toy for experts.

Ultimately, practice is the deciding factor. Anyone using holography to plan more sustainably must be prepared to question old ways of thinking and break new ground. This is uncomfortable, but necessary. The future of sustainable architecture will not be decided on the screen – but in the hologram, which asks more questions than it answers. Those who rise to this challenge can win. Those who focus on the quick effect will quickly end up on the digital sidelines again.

Technical know-how and new professions: Who understands the hologram?

Holography not only turns technology and processes on their head, but also the demands placed on professionals. The classic CAD draughtsman has had its day. What is needed today are specialists who can think and work in three-dimensional, dynamic environments. Spatial designers, data engineers and VR architects are no longer exotic, but key players in the design process. However, training is lagging behind. Universities and universities of applied sciences are experimenting with holographic laboratories, but integration into regular operations remains slow. Most architects and engineers are still learning for the screen, not for the hologram.

Technical know-how is shifting rapidly. Anyone who wants to design successfully today needs knowledge of data management, interface programming and interactive visualization. The ability not only to create BIM models but also to optimize them for holographic presentations is becoming a competitive advantage. At the same time, the importance of soft skills is growing: communication, the ability to work in a team and the willingness to constantly learn new things are more in demand than ever. Holography is not a sure-fire success – it requires a new mindset and a willingness to throw old routines overboard.

The question of accessibility remains central. Not everyone can afford a high-end holography system, and not every office has the human resources to keep up with the technology. The risk of a digital divide is growing. Those who are at the forefront set the standards – those who lag behind become service providers for the big players. This is neither new nor surprising, but it is particularly explosive in times of skills shortages. The industry is faced with a choice: continue to muddle along as before – or invest in training, infrastructure and innovation.

The interfaces with other disciplines are also changing. Urban planners, building physicists and landscape architects must learn to deal with holographic models. The traditional distribution of roles is becoming blurred. Anyone who still believes they can get by as a generalist today will quickly become an extra in the hologram. The future belongs to those who specialize – and at the same time remain open to interdisciplinary collaboration.

The big challenge: how can knowledge be transferred across the board? There are enough pilot projects and lighthouse buildings. What is missing is the nationwide anchoring of holography in training and everyday working life. This is where politics, chambers and associations are needed – and of course the companies themselves. Anyone who remains fixated on the screen will miss out on the next stage of evolution. Those who understand the hologram are shaping the future of architecture.

Global trends, regional realities and the future of design

A look beyond the horizon shows: Holography has long been part of the global architectural discourse. In Asia and North America, immersive design processes are standard in many major projects. Scandinavian countries are investing specifically in research and training in order not to lose touch. Germany, Austria and Switzerland, on the other hand, are still hesitant – the fear of bad investments is too great and the legal framework too unclear. But international competition never sleeps. If you don’t invest today, you will lose out tomorrow – and with it orders, talent and innovative strength.

The debates in the industry are diverse. Some warn against the commercialization of design processes, which loses sight of the added value for users. Others see the danger of algorithms and holograms restricting the creativity of architects. Still others fear a loss of control over data and processes. But the truth is: holography is here to stay. It will not replace the design process, but it will fundamentally change it. Those who ignore this will soon be playing second fiddle.

The role of AI and digitalization should not be underestimated. They are the prerequisite for holography to be used sensibly at all. Only those who structure data properly, link models intelligently and design processes flexibly will be able to exploit the technology’s full potential. The challenges are enormous: interoperability, data security and standardization are unresolved issues. But the pressure is increasing – from clients, investors and not least from the users themselves.

The impact on the architectural profession is massive. Traditional skills are no longer enough. If you want to work seriously with holography, you have to keep learning, master new tools and be prepared to take responsibility for complex, networked processes. This is uncomfortable, but unavoidable. The architecture of the future is digital, collaborative and immersive – and the hologram is becoming the new gold standard.

The question of the sense and nonsense of holography will occupy the industry for a long time to come. But one thing is clear: the freedom to ignore the new technology will soon no longer exist. Those who experiment, learn and invest now have the chance to set the standards of tomorrow. Those who wait will be overrun by the next wave of innovation. Welcome to the world after the screen.

Conclusion: the hologram is coming – and the screen is going

Holography is more than just a fancy gimmick. It is the design medium of the future – and it poses huge challenges for the industry. Those who continue to stare at the screen are missing the opportunity to revolutionize the design process. The technology is there, practice is slowly catching up. What is needed now is courage, openness and the willingness to cut off old habits. The screen was yesterday. The hologram is the new reality of design. Anyone who misses out on this will soon be nostalgic for the days when renderings were the measure of all things. The future is spatial, immersive and – finally – tangible.

Positive insights from the coronavirus crisis – home office cultural tip

Positive insights from the corona crisis – This is the title of the interview between Gabi Wuttke and Matthias Sauerbruch from Sauerbruch Hutton Architekten for Deutschlandfunk Kultur.

What does the shutdown mean for architects? This question was the focus of the conversation entitled “Positive insights from the coronavirus crisis” between Gabi Wuttke and Matthias Sauerbruch from Sauerbruch Hutton Architekten on April 5. Deutschlandfunk Kultur recorded the interview. You can read about the topics they discussed here.

What impact is Covid-19 having on the construction industry? Serious ones, if a survey is to be believed. According to the survey, architectural firms in Germany are seeing a 45 percent drop in orders. “The situation varies from office to office. Personally, I have noticed a slowdown so far, but not a standstill,” says Sauerbruch.

Work is still continuing on construction sites in Germany. But tradespeople from abroad are missing, as they can no longer enter the country due to the shutdown. “The teams are severely decimated, so everything is slowing down. In addition, supplies are not coming in and certain building materials from abroad, such as equipment from Italy, are no longer available,” reports Sauerbruch.

“The new communication channels are working so far, but they are more complicated, so everything is slowing down.” 90 percent of Sauerbruch’s employees work from home. They communicate via email, telephone and video. If they continued to communicate digitally to this extent after the shutdown, they would no longer have to travel as much. A positive learning effect, according to Sauerbruch.

Changing competitive landscape

“How do you see the future of new construction projects, tenders and competitions?” was another question posed by the moderator to the architect and Head of the Architecture Section of the Berlin Academy of Arts. The architectural competitions that had been planned long in advance would continue and be brought to a conclusion. “The submission deadlines were postponed almost without exception in order to meet the circumstances.”

A new starting position also requires new solutions: Sauerbruch, for example, held its first online jury at the end of March. Two thirds of the judges were connected via video conference. “Everything is possible, it just takes some getting used to. We have to adopt new techniques.” However, Sauerbruch does not know what the situation is regarding completely new procedures and future competitions. “Everyone is waiting and seeing what comes next.”
