Industry Report – STEIN, June 2024

Building design

In STEIN 6/24, we showcase the new spa area of a luxury hotel in Austria, which star architect Hadi Hadi Teherani has artfully integrated into the landscape—and, of course, it features plenty of Rauris marble. We also attended a parliamentary evening event on the construction transition featuring natural stone and provide a detailed overview of the happenings at the Stone+tec 2024 trade show.

Stone+tec is just around the corner and already has some good news to share. According to the trade show organizer Afag, it will be significantly larger than it was two years ago. With the addition of Til+tec, the entire tile sector is now included as well. To find out what awaits you, dear readers, at the trade show in Nuremberg from June 19 to 22, turn to page 38. Our machinery expert Michael Spohr has been talking to industry insiders and presents the most important innovations on the exhibition grounds.

In an interview with Stone+tec project manager Michael Löffler (starting on page 48), you’ll also learn what to expect during the three-day conference. Here’s a sneak peek: The range of topics is broad, spanning from “The Future of the Cemetery” to “Massive Building Structures Made of Natural Stone.”

Building with natural stone is naturally very close to the hearts of the leaders at the DNV. That’s why they recently hosted a parliamentary evening in Berlin to draw politicians’ attention to natural stone—an often-overlooked but truly sustainable building material. STEIN was there for you. Read our detailed report on this starting on page 18.

Starting on page 6, you can see and read about how world-renowned architects incorporate this material into their designs. Rauriser marble adds its own distinctive touch to the new spa at the luxury Krallerhof Hotel in Leogang. Star architect Hadi Teherani has realized a project here that shines far beyond Austria’s borders, proving once again that architecture and nature can indeed coexist in harmony.

Entirely different boundaries are being crossed today in the skilled trades as robots come into play. Find out what is now “state of the art” alongside the already familiar drone in our article starting on page 26.

Light and shadow in Cologne

Building design

L.-Fritz-Gruber-Platz is only about 400 meters away from Cologne Cathedral as the crow flies. For its design, the Düsseldorf-based firm scape Landschaftsarchitekten took up the theme of photography. The result is a play of light and shadow.

L. Fritz Gruber Square is located just 400 meters from Cologne Cathedral as the crow flies, right next to the Kolumba Art Museum of the Archdiocese of Cologne, which was built in 2007 according to plans by Peter Zumthor. The square is named after the photographic historian and journalist Leo Fritz Gruber. From 1945, he worked as a photographer for the British Army of the Rhine. This passion never left him. The Düsseldorf-based firm scape Landschaftsarchitekten therefore took up the theme of photography for the design of the square. A play of light and shadow creates a two-dimensional image of the large maple trees on the square. The square is bordered by listed facades from the 1920s and 1960s. Typical local basalt cobblestones surround a rectangular area of light-colored concrete slabs with an aspect ratio of 6:9 (small picture format), which is framed by three white cuboid benches.

Shadow plays are created on this projection surface, which is illuminated at night by a luminaire hanging above the square in the shape of a hollow sphere. Objects that cross its beam of light create sharply defined shadows on the paving. The functional principle is similar to that of a projector: a hollow body with a matt black inner surface and a point-shaped light source, the opening of which is dimensioned at the bottom so that the focal point beams precisely trace the surface of the square.

A stroke of art-historical luck

Building design

The Gothic sacristies of the parish church of St. Quirinus in Tegernsee are to be restored. Many eras have left their mark on St. Quirinus, which was the monastery church of the most important Benedictine abbey in Upper Bavaria until 1803.

The Gothic sacristies of the parish church of St. Quirinus in Tegernsee are to be restored. Many eras have left their mark on St. Quirinus, which was the monastery church of the most important Benedictine abbey in Upper Bavaria until 1803.

The sacristy used today dates from the Baroque period, but the two Gothic sacristies with their vaults and rare gray-on-gray painting are a stroke of art-historical luck. These are now used as storerooms, albeit for valuable items from the monastery or handicraft objects such as candlesticks or figurines.

The approval of the preliminary investigation for the restoration means that the sacristies will now be cleared out so that they can be made accessible to the public at some point in the future. Church historian Roland Götz has taken a closer look at the sacristies and knows that their preservation is a stroke of luck. However, fire protection still needs to be clarified, as there are no escape routes. As the church is under the same roof as the Bräustüberl, the castle distillery, the grammar school and the brewery, all those responsible and the owners must first come to an agreement. How much all the measures would cost is now to be found out in advance.
