Vertical access is the backbone of every building – and yet the competition between stairs, ramps and elevators is far too often dismissed as a banal compulsory exercise. Anyone who still believes that an escape route and a box in the shaft are enough has missed the signs of the times. The future of vertical access is smart, sustainable, integrative – and a damn hotbed of innovation, controversy and vision between architecture, technology and society.

The present of the vertical: Between duty and freestyle

Vertical development is as ubiquitous in architecture as it is underestimated. In many places in Germany, Austria and Switzerland, it symbolizes the dilemma between compliance with standards and creative ambition. Building regulations dictate the minimum, but the reality of planning is rarely minimalist. The classic flight of stairs, the technically correct inclined ramp and the obligatory elevator have long since ceased to be self-serving constructions. Instead, they are the stage for social negotiation processes, the setting for technical innovations and an indicator of a project’s approach to accessibility, sustainability and user experience.

In German-speaking countries in particular, there is a remarkable tension between tradition and progress. In Vienna, for example, the integration of ramps in listed ensembles is becoming a political issue, while in Zurich the elevator is being discussed as the energy Achilles heel of zero-energy buildings. In Berlin, on the other hand, disputes are raging about the design quality of emergency staircases – often at the expense of the overall architectural concept. The truth is that anyone planning vertical development today is not only deciding on accessibility, but also on the fundamental approach to building itself.

The pace of innovation is unmistakable. Modular staircase systems, adaptive ramp profiles and digitally networked elevators show that the days of static solutions are over. At the same time, regulatory pressure is growing: accessibility is no longer a bargaining chip, but a basic requirement. The new DIN 18040 standard in Germany, the SIA standards in Switzerland and the Austrian Federal Disability Equality Act set standards that demand more than just lip service. And while the authorities are following suit, innovative architectural firms and manufacturers have long since recognized the signs of the times.

But everyday life remains contradictory. While elevator manufacturers advertise AI-supported maintenance forecasts, the ramp in existing buildings is being forced into the stairwell with a crowbar. While the smart building platform in Zurich links elevator use with public transport, elsewhere there are still discussions about the minimum width of the emergency staircase. Vertical access is not just a side issue – it is a focal point for the innovative capacity of architecture and the construction industry.

The paradigm shift has long been underway. Anyone planning today must ask themselves the question: Is it enough to meet the standard – or is it about understanding accessibility as an integral part of a sustainable, digital and socially inclusive building? The answer separates mediocrity from excellence.

Technology, trends and digital revolutions

What happens in the stairwell is no longer just a question of statics and handrails. Digitalization has vertical development fully under control – and opens up a playing field that ranges from predictive maintenance to augmented reality. Artificial intelligence analyses usage profiles, optimizes cycle times and detects faults before they reach the user. Sensor technology monitors vibrations, air quality and frequencies, and smart elevators are now standard in high-rise buildings in particular. This has consequences for planning, operation and maintenance – and is fundamentally changing the role of architects and engineers.

The digital twin is not just a buzzword for urban planning, but is also finding its way into vertical development. Modern elevator systems are now being designed as part of the building data model, including lifecycle management and real-time monitoring. Stairwells are equipped with IoT components that dynamize lighting, ventilation and access control. Ramp profiles can be adapted to user flows and mobility requirements with simulation support. The elevator, once a symbol of convenience and technophobia, is suddenly becoming a data supplier in the smart building.

Despite all the technology, the focus is still on people. User comfort is no longer measured by the lowest common denominator, but by the ability to anticipate needs. Adaptive systems adjust to peak times, emergencies and individual requirements. Zurich is experimenting with elevators that can be called by app and save individual settings. In Vienna, ramps with weather-dependent heating are being tested and in Munich, smart emergency stairwells are being equipped with digital routing. This sounds like a dream of the future, but it is already a reality in many places.

The innovation spiral is turning faster than ever. New materials, modular construction systems and AI-supported planning processes are increasingly blurring the boundaries between stairs, ramps and elevators. Hybrid systems, such as the integration of platform lifts in ramp systems or the combination of stairs and escalators in public spaces, show that the classic tripartite division of vertical access is no longer up to date. Those who do not keep up to date here risk being overtaken by developments.

But as technology grows, so do the challenges. Data protection, technological dependencies and the danger of digital overkill are real risks. The debate about open interfaces, proprietary systems and the role of manufacturers has long since flared up. One thing is clear: the future of vertical access is digital, but it remains a field for critical debates about control, transparency and user autonomy.

Sustainability, inclusion and the new responsibility

Sustainability is the big buzzword – and vertical access can score points or fail here. The ecological footprint of an elevator is considerable, especially in existing buildings. Modern elevator systems therefore rely on energy-efficient drives, regenerative braking and the use of resource-saving materials. In Switzerland, the CO₂ footprint of elevator components is now part of environmental certification, with the first pilot projects following in Germany and Austria. But a green elevator alone does not make a sustainable development.

Stairs are making a comeback in this context. As an active access element, they promote movement and health, save energy and resources – and yet are often overshadowed by elevators. Innovative architectural firms are therefore focusing on staging: visible, inviting flights of stairs are becoming a design statement and social meeting point. Inclusion is not seen as an obligation, but as an opportunity to create spaces for everyone that meet the needs of children, senior citizens and people with limited mobility in equal measure.

The ramp, often ridiculed as the unloved stepchild of accessibility, plays a central role in the debate on participation. Its space requirements and design integration present planners with challenges that can only be solved with interdisciplinary expertise. However, adaptive ramp solutions, folding systems and innovative materials show that the time for excuses is over here too. In Vienna, a school building was recently awarded a prize for using a spiral ramp to create not only accessibility, but also quality of stay and play areas. Anyone who plans the ramp as a mere stopgap solution has not understood what it is all about.

Sustainability also means considering the life cycles of the systems. While stairs and ramps are considered low-maintenance endurance runners, the elevator is a complex structure with high maintenance requirements. Predictive maintenance, recycling concepts and modular replacement systems are therefore becoming the new standard. In Zurich, for example, there are elevators that consist of 90 percent reusable components. The future of development is recyclable – or it is not a future.

However, the biggest challenge remains the social dimension. Accessibility is not an add-on, but a basic right. Society expects buildings that are open to all – and the technology must deliver. The days when stairwells functioned as “social filters” are definitely a thing of the past. Anyone planning today is planning inclusively – or not at all.

Expert knowledge, debates and visions for practice

Vertical development is a field for specialists – and for generalists with technical depth. Today, architects and engineers need to know more than just gradients, platform widths and shaft dimensions. Fire protection, sound insulation, user behavior, energy efficiency, digital integration and life cycle costs are just some of the parameters that determine a modern access concept. Those who maintain an overview can control innovations with confidence – those who rely on standard solutions will quickly be left behind.

In practice, the debates are becoming more heated. The question of whether stairs, ramps or elevators take precedence is not a purely technical one, but a socio-political one. In Germany, the discussion is often sparked by the costs: who pays for accessibility and how can it be more than just a minimum standard? In Switzerland, the focus is increasingly on user comfort and quality of stay, while in Austria, integration into existing buildings is a hotly debated topic. The debate about “silent discrimination” due to missing or poorly planned development has long been mainstream.

The role of digitalization is ambivalent. On the one hand, it enables an unprecedented level of precision and efficiency. On the other hand, it threatens to exclude the user from the process. The best planning and maintenance algorithms are of little use if they ignore the needs of the user. Practice shows: Those who see digital tools as a supplement and not a replacement will win. People remain the benchmark – even in the age of artificial intelligence.

There are plenty of visionary ideas – such as self-learning elevator systems that adapt to individual mobility profiles, or stairwells as flexible meeting spaces that change depending on the time of day. But the reality is still characterized by compromises. Fire safety regulations, costs and technical feasibility set limits that can only be overcome with creativity and interdisciplinary cooperation. Vertical development is therefore less a product than a process: it requires constant reflection and further development.

These issues are being discussed intensively in the global discourse. Scandinavian countries are experimenting with multifunctional ramp landscapes, while elevator systems that are part of local public transport are being developed in Asia. The German-speaking countries are not pioneers here, but they are not laggards either. International networking, for example via BuildingSMART or European research projects, ensures that impulses are absorbed – and critically scrutinized. The future of vertical development is emerging in the area of tension between the local and the global, between technology and society.

Summary: More than just up and down

Vertical access is an underestimated but highly complex field that goes far beyond the question of stairs, ramps or elevators. In Germany, Austria and Switzerland, change is palpable: digitalization, sustainability and inclusion are driving innovation and debate. Anyone planning, building or operating today must combine technical excellence with social responsibility and visionary thinking. The future belongs to those who see development not as an obligation, but as an opportunity. Because in the end, it’s not the technology that counts, but the attitude with which we create spaces for everyone.

Pritzker Prize, this time again as a star award

Arata Isozaki, that is. This year. Born in 1931, the architect, urban planner and theorist was awarded the 2019 Pritzker Prize. And reactions are mixed.

Arata Isozaki, that is. This year. Born in 1931, the architect, urban planner and theorist has been awarded the Pritzker Prize 2019. And reactions are mixed. Once again. Some are surprised that the man, whose well-known buildings (such as the Museum of Contemporary Art in Los Angeles or the Olympic Stadium in Barcelona) have all been standing for a while, had not received the major prize long ago. Others find the choice sensible; but some also find it rather unnecessary – why honor someone whose work is nearing its end, why not rather choose someone for whose (or whose) work the award can be a driving force? My colleagues in the editorial team reacted rather bored.

I think the Pritzker jury needs to make up its mind when it comes to award policy. At the moment, too many different motives seem to exist in parallel. Is this an award for a significant life’s work? For interesting offices that may be the future? For relevant political approaches? Each direction on its own is possible. All together is probably not.

And incidentally, I stand by the opinion I expressed two years ago: the Pritzker Prize is awarded too often. Every three, or even better, every four years would be a more sensible frequency.

Nevertheless, this should not go under: Congratulations, Arata Isozaki.

Oberwart is getting a green promenade designed by 3:0 Landschaftsarchitektur. The Vienna-based firm won the architectural competition for the redesign of Oberwart’s town center.

More greenery for Oberwart town center

The redesign of Oberwart town center began back in summer 2021. At that time, the city launched a citizen participation project. The aim was to find out the needs of the population. The guiding principle behind the project was the intention to transform Oberwart into a more liveable place. In addition, the city was to become more forward-looking and climate-friendly. The participation process in March 2022 was therefore followed by an open architectural competition. Eight projects were submitted in the process. The winning office has now been chosen. 3:0 Landscape Architecture from Vienna won over the nine-member jury. Their vision for the new Oberwart town center meets the wishes of the citizens. For example, they had called for more greenery and less traffic in the town center. They also wanted cozy squares with more places to spend time. In addition to the feedback from the participation process, there were also other aspects to consider.

Challenges of the planning task

For example, the design quality of the landscape architecture was a key aspect. However, the designs also had to respond to the traffic conditions. The primary aim was to reduce traffic in the city center. At the same time, the needs of the local businesses had to be taken into account. 3:0 Landscape Architecture succeeded in taking all these aspects into account in their planning – by developing the Oberwart city promenade. This extends as a green ribbon for everyone from Rathausplatz to the Südtiroler Siedlung. The planting of new trees, water elements and plenty of seating provide an ecological and aesthetic upgrade. Furthermore, different spatial characters are created.

One ribbon – three characters

A front garden promenade is being created in front of the South Tyrolean settlement. It will serve as a haven of peace in the development. In addition to play and sports equipment that appeals to young and old alike, magnificent shrub beds and flowering meadows are also being created here. The so-called “twin gardens” are planted with fruit trees and create impressive flowering aspects throughout the year thanks to their biodiversity. Opposite the entrance to the town in front of the South Tyrolean settlement is the town hall square. Here, a more representative character is created, which pays tribute to the buildings of the town hall and district court. The spacious center of the square is designed to be flexible. It offers space for small and large events. The space is structured by two stringent tree grids. In addition to the shade cast by the trees, the new fog fountain also helps to cool the urban space. It also serves as a design accent that invites people to play in the swathes. The market promenade stretches between the two squares. In future, residents will be able to take a relaxed stroll under the planned avenue of trees. Seating areas invite people to linger.

Oberwart becomes climate-ready

Mayor Georg Rosner is highly satisfied with the jury’s decision. He is also certain that this will initiate a forward-looking process: With the plans presented today, we are taking an important step towards redesigning the town center. In 3:0 Landscape Architecture, the city has found an experienced partner in the climate-sensitive transformation of squares and cities. In Oberwart, for example, 3:0 Landscape Architecture is now planning to plant 200 trees according to the sponge city principle. The aim is to ensure that the city center is also prepared for prolonged periods of heat. Furthermore, surfaces open to evaporation will be laid in light shades of color. These are used for rainwater management. They also counteract heat storage. The climate-friendly promenade will thus become a green backbone for Oberwart, which will have a lasting positive impact on the city.

Steps towards realization

Until the project can be realized in 2024, the negotiation process is still pending. Among other things, it will be important to determine which preparatory and accompanying measures are necessary. By communicating with all parties involved in advance, the construction work should not interfere with business activities. Once all agreements have been made, the municipal council will decide to commission the work. And thus the green light for the realization of the new Oberwart city promenade.

The cooling of the square is directly considered by 3:0 Landscape Architecture. A retrofit that was necessary for Turbinenplatz in Zurich. A fog cloud is currently installed there as an immediate measure to cool the square in the medium term. Read here how this pilot project works: Alto Zürrus
