“Interior” – sounds like sofa cushions and curtain advice? Far from it. Anyone who still believes that interior design is the icing on the cake of architecture has missed the big picture. In fact, “interiors” have long since shaped the DNA of our building culture – and are becoming a game changer thanks to digitalization, sustainability pressure and new usage concepts. High time to sharpen our focus: How is the interior revolutionizing design? Who is ahead of the game? And why is real interior design the hardest currency in the architecture business?
- Interior design is no longer decoration, but the defining force of architecture.
- Germany, Austria and Switzerland are facing a paradigm shift – interiors are becoming a driver of innovation.
- Digitalization and AI are radically changing material selection, planning processes and user participation.
- Sustainability demands circular and adaptive interior solutions instead of disposable designs.
- Professional skills are shifting: data sovereignty, BIMBIM steht für Building Information Modeling und bezieht sich auf die Erstellung und Verwaltung von dreidimensionalen Computermodellen, die ein Gebäude oder eine Anlage darstellen.

- Interiors have become the arena for social debates – from New Work to inclusion.
- Global trends such as adaptive reuse, cradle-to-cradle and smart interiors show: The interior dominates the future.
- The boundaries between architecture, interiors and cities are blurring – and challenging old role models.
The interior as an architectural machine: status quo in DACH
Anyone talking about interior design today needs to dress warmly. Because the term has become a battleground: A new self-confidence has long prevailed between architects, interior specialists, clients and users. The interior is no longer a stage for a few pieces of furniture, but shapes the behavior, identity and even the performance of a building. This rethink is noticeable in Germany, Austria and Switzerland – albeit with regional nuances. While in Vienna the classic coffee house interior is defended as a cultural asset, offices in Zurich are experimenting with flexible, sensor-equipped working landscapes. In Berlin, historical buildings are being radically reprogrammed: From old apartments to hybrid living spaces, from workshops to collaborative co-working spaces. Interiors are being rethought, recoded – and reassessed. The once neglected discipline is becoming an innovation platform, an architectural machine that is turning entire building concepts upside down. But despite all the euphoria, implementation is lagging behind across the board. The investor perspective, which sees the interior as a cost factor, still dominates. The interior is still too often sacrificed to quick taste. But the exceptions are growing – and with them the awareness that spaces must be developed from the inside out. The DACH region is at a crossroads: those who recognize the potential will be playing in the Champions League of building culture tomorrow.
Digitalization is both a driver and a brake. While BIMBIM steht für Building Information Modeling und bezieht sich auf die Erstellung und Verwaltung von dreidimensionalen Computermodellen, die ein Gebäude oder eine Anlage darstellen. BIM wird in der Architekturbranche verwendet, um Planung, Entwurf und Konstruktion von Gebäuden zu verbessern, indem es den Architekten und Ingenieuren ermöglicht, detaillierte und integrierte Modelle... integration of interiors is almost standard in Zurich, German planners are struggling with incompatible software solutions and a lack of interfaces. Austria is focusing on pilot projects in which digital twins no longer stop at the façade, but record the user flow, indoor climate and furnishings. Switzerland is a pioneer in sensor-based room concepts that react to user behavior in real time. But the road ahead is rocky: standardization, data protection, technical interoperability – all of these are slowing down the big breakthrough. But: the direction is right. Anyone who still believes today that interior design is only about changing the wallpaper will be overrun tomorrow by AI-generated, parametrically optimized room concepts.
The interior has also become an arena for debates on sustainability. Whereas just a few years ago the fast furniture collection was considered a status symbol, the focus is now shifting to the circular economy. In DACH, more and more offices are focusing on reusable materials, modular systems and adaptive usage concepts. The interior is becoming a test track for new lifestyles: Sharing, upcyclingUpcycling - Der Prozess, bei dem Abfallprodukte oder Materialien in Produkte von höherem Wert umgewandelt werden., minimal footprint. But here, too, legislation is lagging behind, building regulations are silent on interior design – and the market is sluggish. Nevertheless, the pressure is growing because users demand more than just beautiful surfaces. They want healthy, flexible and sustainable spaces. Anyone who doesn’t deliver here is out.
And finally: the profession itself is changing. In the past, interiors were the domain of specialists; today, generalists with digital, technical and design expertise are needed. Training is lagging behind and professional associations are discussing new certifications. Anyone who wants to survive in the interior field must be able to program, model and moderate. This is the only way to solve the complex requirements between technology, sustainability and user experience. The days of pure aesthetics are over – interior design has matured into a highly complex discipline that is redefining the foundations of architecture.
Conclusion: The DACH region is at the beginning of a revolution. The interior is no longer treated as a sideshow, but is moving to the center of the architectural debate. Those who do not follow suit now will be overtaken by the next generation of smart, sustainable and digital spatial concepts. Inside is the new outside – and those who understand this are building the future.
Digital spaces: how AI, BIM and user tracking are rewriting the interior
Digitalization has arrived in the interior – and with full force. While some architects are still working on the façade, AI, BIMBIM steht für Building Information Modeling und bezieht sich auf die Erstellung und Verwaltung von dreidimensionalen Computermodellen, die ein Gebäude oder eine Anlage darstellen. BIM wird in der Architekturbranche verwendet, um Planung, Entwurf und Konstruktion von Gebäuden zu verbessern, indem es den Architekten und Ingenieuren ermöglicht, detaillierte und integrierte Modelle... and smart homeSmart Home: Ein Smart Home bezeichnet ein intelligentes, vernetztes Zuhause, in dem Haushaltsgeräte und -systeme über eine App oder Sprachsteuerung gesteuert werden können.

What does this mean in concrete terms? FirstFirst - Der höchste Punkt des Dachs, an dem sich die beiden Giebel treffen. of all, the traditional design process is a thing of the past. Today, rooms are optimized parametrically, user behaviour is tracked, light, acoustics and climate are simulated in real time. The boundaries between architecture, interiors and technology are becoming blurred. Planners who are not at least BIM-savvy will fall by the wayside. In practice, this means that even in the early design phase, material databases are tapped into, usage profiles are created and variants are run through – all based on real data, all networked, all scalable.
What is particularly exciting is that AI-based tools not only generate attractive renderings, but also optimize spaces according to criteria such as quality of stay, energy efficiency and accessibility. The planner becomes a curator who distils the optimal room concept from a flood of data, scenarios and user feedback. In Switzerland, such processes are already part of everyday life: sensors measure CO₂ pollution, AI suggests changes of use and the system learns from the residents. In Germany and Austria, such approaches are still exotic, but the pressure is growing. After all, anyone who sleeps through digitalization will end up in a museum – and this applies not only to technology, but also to attitudes.
But digitization is not an end in itself. It is a tool for creating real added value: Healthier spaces, lower resource consumption, better user experiences. This requires technical expertise – and this goes far beyond traditional architectural studies. Anyone planning interiors today has to juggle databases, read program code and design interfaces. The days when a mood board was enough are definitely over. Anyone who is not prepared to plunge into the digital depths will be left behind.
At the same time, new areas of conflict are emerging: Who owns the data? Who decides what counts as an “optimized interior”? And how do we prevent algorithmic distortions from creating new forms of discrimination? The discussions are heated – and they will become even more so. One thing is clear: transparency, interoperability and user participation are the new key currencies. Those who slip up here will lose the trust of users – and thus their market success.
From an international perspective, German-speaking countries are both laggards and pioneers. While Asian cities are experimenting with fully networked smart interiors, DACH planners are focusing on quality, sustainability and data protection. This is not a disadvantage – on the contrary. Those who combine the best of both worlds will become role models. The future of interiors is digital, participative and sustainable. Everything else is folklore.
Sustainability and the new interior: Between greenwashing and genuine transformation
Sustainability in interiors – sounds like an eco-cliché? Not any more. Anyone planning seriously today cannot ignore the circular economy, resource conservation and adaptability. The interior has become the key zoneIn der Architektur und Gebäudetechnik bezeichnet eine Zone einen Bereich innerhalb eines Gebäudes, der in Bezug auf Heizung, Klimatisierung oder Belüftung eine eigene Regelung benötigt. Zonen werden oft nach ihrer Nutzung, Größe oder Lage definiert, um eine maßgeschneiderte Versorgung mit Energie und Luft zu gewährleisten.... for sustainable innovations. While the PV system still shines on the roof, the interior determines how long a building will really last. This is where ventilation takes place, where heating takes place, where materials are worn out or recycled. In the DACH region, the approaches are diverse: the spectrum ranges from modular partition walls in Viennese office buildings to recycled acoustic panels in Swiss schools. But they all have one thing in common: the aim of no longer seeing interiors as “consumables”, but as a resource in the building cycle.
The biggest challenges are obvious. Firstly, the consumption of materials is enormous. Tons of carpet, plasterboard and furniture still end up in landfill as soon as there is a change of user. Secondly, the lifespan of interiors is often disappointingly short. Quick in, quick out – that’s ecological madness. Thirdly, technical complexity is increasing. Circular systems, smart ventilation, adaptive lighting – it all needs to be planned, controlled and maintained. If you don’t pay attention here, you will produce chic but highly problematic high-tech tombs.
But there are solutions. Circular design principles such as cradle-to-cradle, modular construction kits and flexible furnishing concepts make a real transformation possible. In Switzerland, interiors are conceived as reversible systems: everything can be dismantled, everything is recyclable. In Germany, the firstFirst - Der höchste Punkt des Dachs, an dem sich die beiden Giebel treffen. large-scale projects are experimenting with digital material passports that document the life cycle of each component. Austria is focusing on regional supply chains and local craftsmanship – not out of nostalgia, but as a response to global supply bottlenecks and climate pressure. The future of sustainable interiors lies in an intelligent mix of high-tech and low-tech, digital control and quality craftsmanship.
Professional planners must adapt to new rules of the game. It is no longer enough to stroke material samples and collect eco-labels. Knowledge of life cycle assessment, materials research and building technology is required. If you want to build sustainable interiors, you need a toolbox that ranges from material flow analysis to AI-supported operation. The good news is that those who invest here can not only remain competitive, but also create real added value – economically, ecologically and socially.
Of course, there is also criticism. Greenwashing lurks around every corner, marketing promises overtake reality. But the pressure is growing. Users, investors and legislators are demanding evidence, data and transparency. Those who deliver here set standards. Those who continue to rely on facade cosmetics will be left out. The interior has become the touchstone of true sustainability – and only those who act honestly here will survive.
Global perspectives, local answers: Interiors as the laboratory of the future
The interior has long been a global field of experimentation. While tiny micro-apartments in Tokyo make the most of every cubic meter, adaptive loft concepts are being created in New York that merge work, leisure and living. Scandinavian countries are focusing on radical flexibility – rooms are converted to suit the daily rhythm, furniture moves out of the wall and technology disappears out of sight. The international discourse is fast-paced: adaptive reuse, smart materials, sensor technology and AI-controlled control systems are shaping the agenda. What does this mean for the DACH region? On the one hand: inspiration and benchmarks. On the other hand: local building culture, high standards of data protection and a desire for consistency are not weaknesses, but assets. Those who cleverly adapt global trends instead of blindly copying them will become pioneers.
The great visions are currently coming from two directions. Firstly, the merging of inside and outside. Boundaries are blurring, loggias are becoming living spaces, offices are becoming neighborhoods, facades are becoming active interfaces. Secondly, the democratization of the design process. Users are no longer just consumers, but co-creators. Digital tools, open source platforms and participatory planning processes are turning the interior into a collective project. In Switzerland, participatory housing models have long been part of everyday life, and German cooperatives are following suit. Architecture is becoming a social laboratory, the interior a playing field for new ways of living and working.
But with this opening up comes new risks. Commercialization, data exploitation, technocratic bias – all this threatens if digital control takes place without social control. The debates about smart homes, surveillance and algorithmic discrimination are just the beginning. Those who fail to take countermeasures here risk turning the interior into a surveillance zoneIn der Architektur und Gebäudetechnik bezeichnet eine Zone einen Bereich innerhalb eines Gebäudes, der in Bezug auf Heizung, Klimatisierung oder Belüftung eine eigene Regelung benötigt. Zonen werden oft nach ihrer Nutzung, Größe oder Lage definiert, um eine maßgeschneiderte Versorgung mit Energie und Luft zu gewährleisten..... Transparency, ethical guidelines and open standards are therefore not a luxury, but a necessity for survival.
At the same time, the global discourse offers enormous opportunities. Interdisciplinary teams, international partnerships and the exchange of best practices accelerate innovation. Anyone who ventures onto the global stage as a planner, developer or investor benefits from knowledge, networks and new markets. The interior has become an export product – made in DACH, scaled for the world.
The future of interiors is hybrid, digital and sustainable. Anyone looking to catch up now must be prepared to cut off old habits – and leave their comfort zoneIn der Architektur und Gebäudetechnik bezeichnet eine Zone einen Bereich innerhalb eines Gebäudes, der in Bezug auf Heizung, Klimatisierung oder Belüftung eine eigene Regelung benötigt. Zonen werden oft nach ihrer Nutzung, Größe oder Lage definiert, um eine maßgeschneiderte Versorgung mit Energie und Luft zu gewährleisten..... The interior is no longer a playground, but the laboratory of tomorrow’s architecture. Those who understand this will set impulses – locally and globally.
Conclusion: Interior is the new foundation – and the toughest touchstone of architecture
The days when “interior” was dismissed as a decorative add-on are finally over. Interiors have become a matrix in which sustainability, digitalization and social change are condensed. This is a double challenge for professionals in architecture, planning and the real estate industry: those who do not see the interior as a strategic field will lose out. But those who boldly break new ground – digitally, circularly, participatively – can actively shape building culture. The interior is the new exterior, the laboratory, the foundation and the touchstone at the same time. The future of architecture will be decided in the interior. Those who oversleep this will wake up in the museum.
