The Draenert furniture manufactory has been producing exclusive designer furniture for over 55 years. In Immenstaad on Lake Constance, dining and coffee tables as well as chairs are created using traditional craftsmanship, with many table tops made of natural stone. Dr. Patric Draenert, who holds a doctorate in business administration, has been running the family business for more than 25 years. Draenert specializes in individual, high-quality products for the private and contract sectors. The collections include dining and coffee tables, chairs and individual pieces of furniture. Draenert produces around 1,200 stone tables per year. Each one is processed, milled and brushed by hand. "Natural stone offers countless possibilities thanks to its variety of colors," enthuses the company boss. "There are always new, sensational varieties." New stones are also constantly being discovered - for example from quarries in Brazil, Turkey, Saudi Arabia, Dubai and Oman. "The stone deposits are inexhaustible." Cover picture: Draenert

STEIN 10/25 presents outstanding examples of successful interior design with natural stone. For example, we show a villa in Portugal in which stone from all over the world has been used in a wide variety of places. Furniture made of stone naturally plays a prominent role. Our latest issue also features new tables from the Immenstaad-based manufacturer Draenert and extraordinary furniture made of natural stone from the Italian luxury label Neutra. The latter skillfully staged in the Palazzo Visconti in Milan.

Natural stone from all over the world is used to create extraordinary living environments. This is not only functional, but also expresses a sense of life and style dedicated to luxury. This was once again impressively demonstrated at this year’s furniture fair in Milan. The new tables from Immenstaad-based furniture manufacturer Draenert and the new collection from Italian luxury label Neutra are a fine example of this in the truest sense of the word.

From page 6, our author Dr. Alexandra Nyseth takes you to Portugal. There, under the aegis of the Stuttgart-based architects Ippolito Fleitz Group, an extraordinary residential building has been created. One of the central design elements used by the planners was natural stone. KMD Natursteine GmbH from Gotha was responsible for the planning, production and installation of all the natural stone work in close cooperation with the architects. The large dining table on the first floor is a particular highlight. Made from the strikingly veined quartzite “Patagonia” from Brazil, the polished top measures an impressive 320 × 130 centimetres. A real eye-catcher.

From page 14, we continue with a look at the fine tables that the Immenstaad-based company Draenert has produced over the last 50 years. The son of the company founder, Patric Draenert, talks to the editors from page 14 about his passion for natural stone. However, this is not the only success factor of the family business.
And what does the newly designed furniture from Neutra mentioned at the beginning look like in detail? Great! Especially when they are so skillfully staged in the Palazzo Visconti in Milan. Read the full story from page 28.

It almost goes without saying that you also need the right machinery for precisely executed natural stone work, as in these examples. Our author Michael Spohr shows you the latest water jet machines, which can cut with an accuracy of up to 0.1 millimetres.

Glasgow Rangers and the art of stadium construction: anyone who believes that stadium architecture is just a question of rows of seats and sausage stands has been asleep for the last two decades. While German planners are still optimizing multifunctional arenas and stacking up sustainability certificates, Rangers and their Ibrox Stadium are setting standards – historically, technically and culturally. Time to take a look at the Scottish stadium landscape and ask: What can DACH planners learn from Glasgow? And why are British stadiums so much more than just concrete and stands?

Ibrox Stadium: between brick romance and high-tech

The Ibrox legend does not begin with the LED strip, but with the façade. While German stadium projects of recent years often land on the periphery like soulless UFOs, Glasgow Rangers’ stadium stands in the middle of the urban fabric – and is itself an urban landmark. The listed brick façade designed by architect Archibald Leitch in 1928 is not just a visual statement, but a clear sign of the stadium’s roots in the neighborhood. It is not being built here for changing event formats, but for eternity – at least in terms of urban planning. In Germany, Austria and Switzerland, on the other hand, pragmatism dominates: multifunctional arenas, whose aesthetics are lost somewhere between an airport and a shopping mall, dominate the scene. But the calculation rarely works out, because identity cannot be milled out of aluminum profiles.

Technically, the Ibrox Stadium has long since followed suit. Modern grandstand structures, optimized escape routes, digitally controlled access systems and a sophisticated lighting concept turn the historic building into a hybrid of tradition and innovation. While elsewhere people are still arguing about whether heritage protection and comfort go together, Glasgow shows how both can be combined with sensitivity and planning expertise. The renovation of the 1990s is still regarded today as a lesson in the respectful treatment of existing buildings and the retrofitting of the latest safety technologies. German, Austrian and Swiss stadiums can only dream of this, as regulations and fear of damaging their image often block bold solutions.

Another unique selling point of Ibrox is the integration of digital tools to control infrastructure, security and the fan experience. Sensor-based access control, dynamic seat allocation and real-time data for the security service have long been standard. While Wi-Fi coverage and app tickets are still being considered in Munich and Vienna, the next steps are already being planned in Glasgow. AI-based visitor flows, personalized offers and a “digital stadium twin” are no longer science fiction, but are being piloted. Here, architecture follows technology and not the other way around – a paradigm shift that is still unfamiliar to many planning offices in the DACH region.

But technology alone does not make a stadium. The atmosphere at Ibrox is fed by more than sound meters and fire dampers. The narrow stands, the steep tiers and the close proximity to the pitch create a “Britishness” that planners on the continent can only dream of. Here, the space is not understood as a neutral vessel, but as an emotional force field. This is no coincidence, but the result of precise architectural decisions – and a building culture that understands the stadium as a social place, not as infrastructure for sponsored events.

The urban integration is also interesting. Whereas in our country, sites are systematically planted from the city center to the highway, Ibrox remains within the fabric of the neighborhood. This creates identification, but also challenges: Traffic routing, noise protection, social conflicts. But instead of ducking away, Glasgow is taking an active approach – using digital city models, but also through traditional participation. A model that has so far been seen more as a risk than an opportunity in the DACH region.

Digitalization and AI: the new planning reality in stadium construction

Anyone who still believes that stadium planning is an analog business should take a look at current developments. Digital twins have also arrived in stadium construction – not as a gimmick, but as a central control instrument. Glasgow Rangers already rely on extensive BIM models that not only digitally record the existing structure, but also simulate variants for conversion, expansion and event management. In Germany, Austria and Switzerland, the introduction of BIM in the stadium sector is still slow. Although there are pilot projects, the integration of architecture, operation and digital simulation often remains piecemeal. This has consequences: While Glasgow evaluates maintenance, energy flows and usage dynamics in real time, people in this country are still working with Excel spreadsheets and gut instinct.

Artificial intelligence is also making inroads. It analyses spectator movement patterns, predicts security risks and optimizes the utilization of infrastructure. For major events, the digital twin can simulate emergency and evacuation measures based on AI scenarios – a level of resilience that has rarely been achieved in German-speaking countries to date. The reasons are well known: Data protection, liability issues and a lack of interfaces are holding back progress. Meanwhile, the Rangers have long been experimenting with predictive maintenance, i.e. the predictive maintenance of technical systems based on sensor data and AI evaluation. This saves costs and increases operational reliability – an argument that should actually convince even skeptics.

However, digitalization is not only changing operations, but also design. Architects now have to think in scenarios, design in data models and react in real time. The job description is shifting: from classic designer to process manager, who must not only focus on form, but also on operation, interaction and sustainability. If you want to keep up with British developments in Germany, Austria or Switzerland, you need digital expertise and an understanding of the logic of the platform economy. After all, stadium construction is no longer a singular construction project, but part of a networked urban system.

The role of open data and participation is particularly interesting. In Glasgow, planning is not just for fans, but with fans. Digital tools make it possible to incorporate user feedback, simulate acoustics and sightlines and adapt hospitality areas. In the DACH region, on the other hand, the expert culture still dominates. Participation takes place, if at all, at the end of the planning process – usually as a fig leaf. The result is stadiums that are technically impressive but remain emotionally cold. Glasgow shows that things can be done differently: involving users at an early stage creates acceptance and identification – and reduces the need for changes later on.

Of course, there are also downsides. Digitalization harbours risks: Algorithmic distortions, surveillance, commercialization of fan data. In Glasgow, this is openly debated, while in German-speaking countries people prefer to remain silent. The future of stadium construction therefore lies not only in new tools, but also in new ethics: transparency, control and democratic governance are required. Those who ignore this risk not only losing the trust of users, but also their own relevance as planners.

Sustainability: between aspiration and reality

Stadium construction and sustainability – an explosive topic. While CO₂ balances and circular materials have long been discussed in Glasgow, the debate in Germany, Austria and Switzerland often remains stuck at certificate level. People are busy waving DGNB logos and energy certificates, but the reality is sobering: stadiums are energy-intensive, take up a lot of space and are generally monofunctional. Glasgow Rangers has opted for a different strategy: preserving existing buildings, intelligent densification, integration of renewable energies and flexible usage concepts. The Ibrox remains a soccer temple, but is increasingly opening up for other events – without losing its character. In the DACH region, on the other hand, the multifunctional concept often threatens to become arbitrary: Hardly any stadiums are really used efficiently all year round, and the vacancy periods are enormous.

From a technical perspective, the challenges are enormous. CO₂-neutral components, efficient heating and cooling systems, sustainable mobility concepts and rainwater management are mandatory – not optional. The Rangers invest in photovoltaics, intelligent lighting and modern insulation without disfiguring the fabric. This succeeds because planning and operation are understood as a unit. In Germany, Austria and Switzerland, separate responsibilities and short-term investment logic often prevent the big picture. Instead of thinking in terms of life cycles, the focus is on rapid amortization – a mistake that pays off.

The pressure is growing. Climate change, scarcity of resources and political requirements demand radical solutions. Glasgow is therefore experimenting with urban smart grids, sharing concepts and sustainable mobility connections. Fans should not only travel emission-free, but also strengthen the local economy. In the DACH region, integration into the urban context often remains piecemeal. Traffic, security, environment – everyone plans for themselves, no one for the whole. The result: stadiums as foreign bodies, not as part of urban life.

There are also differences when it comes to materials. Glasgow relies on durable, low-maintenance building materials and a clear architectural language. In Germany, Austria and Switzerland, lightweight construction and short-term trends dominate. The result is architecture that ages quickly and hardly takes on any patina. If you want to build sustainably, you have to focus on durability, reparability and adaptability. Ibrox is proof that a well-maintained stadium can last for generations – with fewer emissions than any new building.

The bottom line is that sustainability is not an add-on, but must be an integral part of planning. This requires technical expertise, political support and, above all, the courage to take a risk. Those who always play it safe will end up being overtaken by the pioneers. In Glasgow, the change has long since been heralded – in the DACH region, discussions are still ongoing.

Culture, commerce and identity: the stadium as an urban laboratory

No stadium without fans – and no architecture without context. The Ibrox Stadium is much more than a sports venue: it is an anchor of identity, an integration machine and a symbol for the city of Glasgow. The architecture translates this role into built form – with references to history, neighborhood and club tradition. In the DACH region, on the other hand, stadiums are often treated purely as infrastructure. The result: interchangeable buildings that show neither heart nor attitude. Glasgow Rangers do things differently. Here, stadium architecture is seen as a cultural task – and you can see that in every brick.

But the days of pure soccer romance are over. Commercialization, hospitality areas, VIP boxes and naming rights challenge the architecture. In Glasgow, the balancing act is successful: commercial offers are integrated without degrading the stadium to a shopping mall. The balance between tradition and innovation is maintained – a balancing act that is rarely achieved in Germany, Austria and Switzerland. Here, either-or dominates: either cold event architecture or glorified nostalgia. Both lead to a dead end.

Social debates are also reflected in stadium construction. Issues such as inclusion, accessibility and social participation are being tackled head-on in Glasgow. The stadium renovations of recent years have not only improved comfort, but also accessibility. In Germany, Austria and Switzerland, the issue is usually dealt with in a bureaucratic manner. The result: stadiums that comply with standards but are not truly inclusive. Glasgow shows that architecture can take on social responsibility – if the will is there.

Another field is the digitalization of the fan experience. In Glasgow, apps, digital services and personalized offers are used to strengthen the bond with the club. In the DACH region, on the other hand, there is often a fear of alienation: Too much technology, too little emotion – that’s the preconception. But the opposite is true. Those who communicate digitally can create closeness – and diversify the fan base. However, this requires an architecture that enables openness and does not seal things off.

In the end, the question remains: what can German-speaking stadium architecture learn from Glasgow? The answer is uncomfortable. More courage for identity, more integration of technology and tradition, more openness for social debates. The stadium of the future is not a neutral space – it is an urban laboratory in which urban development, culture and innovation are negotiated in a confined space. Glasgow has understood this – now it is up to us to follow suit.

Conclusion: stadium construction is at a turning point – and Glasgow is showing how it’s done

Stadium architecture is not just a question of cubature and comfort. It is a reflection of social values, a testing ground for new technologies and a stage for urban identity. Glasgow Rangers’ Ibrox Stadium exemplifies an approach that combines the past and the future – technically, culturally and socially. While Germany, Austria and Switzerland are still discussing certificates and multifunctionality, Glasgow is already building what others hardly dare to think about. The integration of digitalization, sustainability and fan experience is not a luxury, but a necessity. Anyone who wants to learn from this as a planner, engineer or operator must have the courage to question their own routines and break new ground. After all, the future of stadium construction is not decided in the specifications, but in everyday urban life and in dialog with the people for whom the stadium is being built. Time for an update – not only in Glasgow, but also here in Germany.
