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.

To mark the 50th anniversary of the death of Alberto Giacometti (1901 – 1966), works by the world-famous artist will be exhibited at the Kunsthaus Zürich from October 28 to January 15, 2017. In the exhibition “Alberto Giacometti. Material and Vision – Masterpieces in Plaster, Stone, Clay and Bronze”, his sculptural works will be on display in particular. Like our sculpture of the month for November, “Homme”.

The exhibition presents a total of 150 works on over 1,000 square meters. The focus is on 75 original plaster casts that Giacometti created in his studio and which have rarely been shown to the public. In 2006, the works were donated by his brother Bruno and his wife Odette Giacometti to the Alberto Giacometti Foundation, which is housed in the Kunsthaus Zürich. The Kunsthaus Zürich restored the works, some of which were damaged, for the exclusive exhibition.

In addition to the many plaster works, the exhibition also includes numerous works made of other materials, such as clay or marble, as well as bronze casts. The 46.5 x 32 x 12 centimeter work “Homme” by Giacometti dates from 1927 – a period of his first avant-garde years from 1925 to 1929. The sculpture was made from white marble in his Paris studio. There, the famous Swiss sculptor also created many other heads and figures from clay, plaster or marble.

The painter and sculptor often used plaster for his works. The material allowed him to work on and paint his objects even after they were finished. The exhibition provides a new insight into his creative process – from the early works to the most important works of the late period.
