In our issue on facades, we showcase extraordinary exterior cladding made of natural stone. Among them is the facade of the Congress Center in Heidelberg, which—despite its monolithic appearance—is characterized by its tactile quality and vibrancy. This, in turn, is due to the regional sandstone used: Neckartäler Hartsandstein. At Stachus in Munich, a new building with cubist offsets has recently been elegantly integrated into the historic surroundings. The travertine facade of the new Königshof is a real asset to this location. Even in faraway Helsinki, the city center has gained in elegance. The world-famous Finlandia Hall has been given a new facade made of Laas marble.
There are plenty of good reasons to use natural stone on facades: natural stone is durable, environmentally friendly, visually appealing, and pays for itself through low maintenance costs and a long service life. And yet, according to expert estimates, the market share of natural stone facades in new construction is still well below five percent. But once the decision is made, it’s worth taking a closer look. Starting on page 6, we’ll take you on an exclusive site visit to Heidelberg to see Neckartal hard sandstone.
Less than five percent
The facade of the new Könighof at Munich’s Stachus is also a spectacular sight. With its elegant travertine cladding, the luxury hotel enhances the city center, visible from afar. You can read more about this starting on page 12. Today, Helsinki offers a special gem crafted from white Laas marble: the Finlandia Hall on the shores of Töölö Bay. This world-famous architectural icon by star architect Alvar Aalto had to undergo renovation. Find out why South Tyrolean Lasa Bianco was used and what construction challenges it faced in our report starting on page 22.
From Munich to Helsinki
We’ve already reported on how artificial intelligence can be used in the stonemasonry trade in issue 3/25 of STEIN. Now we’re taking a look at new smart tools for the design and planning of natural stone objects. Everything for the Craft You’ll find essential information about the possibilities and limitations of AI image generators starting on page 40. From July 5 through August 30, the exhibition “Rock your focus” awaits you in Sindelsdorf, Upper Bavaria. Stonemason and sculptor Manfred Dangl is showcasing his artwork there alongside a photographer. Together, they present STEIN in a completely new and surprising context.
