For over 100 years, the Viennese company Derenko has been creating special spatial experiences for the gastronomy, hotel and other business areas in the field of interior architecture. The team of the well-known company thinks passionately and visionarily. A fine example of this is the Kaktus Bar at Seitenstettengasse 5 in Vienna's Bermuda Triangle. Partygoers will find a unique ambience. Furniture, lighting, colours and shapes reveal taste and unconditional attention to detail. And recently, the bar at Vienna's premier address also has a link to Switzerland. The attractively perforated golden ceiling, which is backlit with changing LED lights and thus conveys very different atmospheric images, was laser-cut at Bruag.
