In STEIN 5/25, we showcase large areas subject to heavy use, such as the Quai Zurich Campus in Switzerland. Three courtyards and the facade were designed here using Bollinger sandstone—a tribute to natural stone, not only for its beauty and durability but also for its sustainability. A particular eye-catcher: a twelve-meter-long fountain. Natural stone was also used extensively in the renovation of the Diocesan Museum in Freising. Both historic and new Dietfurt limestone lend the building a special character and sense of quality, both on the facade and inside. For this, the museum was awarded the 2024 Natural Stone Prize. Near Berlin, we take a look at Altlandsberg, where the castle grounds are increasingly transforming into a sought-after cultural and event venue.
According to the German Natural Stone Association (DNV), natural stone in public spaces is currently trending. This sustainable building material is not only weather-resistant but also resistant to wear and tear in high-traffic areas. In addition, natural stone requires only minimal maintenance, making it a cost-effective option for the long-term design of public spaces and heavily used areas.
Low Maintenance
Another key factor in the renovation of the Quai Zurich Campus was that the use of natural stone contributes to reducing CO2 emissions and improving the ecological footprint. The Zurich Insurance Group headquarters is one of the most sustainable buildings in the world, combining historic 19th-century structures with modern architecture. Find out how Austrian architect Adolf Krischanitz approached the project starting on page 6.
Sustainable Project
Natural stone was also used in the renovation of the historic Diocesan Museum in Freising, which was transformed into a transparent, light-filled gathering place. A combination of historic and new Dietfurt limestone gives the building a distinctive character, both on the facade and inside. For this, the museum was awarded the 2024 Natural Stone Prize.

Award for a Special Aesthetic Impact
Large areas of natural stone in outdoor spaces are ideal for barrier-free urban planning. Historic paving, in particular, can be found in numerous market squares, pedestrian zones, and traffic-calmed streets. Find out on page 34 which machines stonemasonry companies use when the ravages of time turn natural stone into a tripping hazard, when there are slip hazards, or when barriers that are difficult to overcome have developed.
For Accessibility
And there’s another topic that’s currently a top priority for nearly a third of companies that we’d like to bring to your attention: succession planning. How do you even find potential successors, and what do you need to keep in mind? Read more about this starting on page 44.
