Sonnenstein Castle | Pirna

Renovations while observing regulations on the protection of historical buildings and monuments

An architectural monument is revitalized as a modern district administrator’s office

Sonnenstein Castle is perched on a hill approximately 70 m above the Elbe Valley. It provides a sweeping view of the historic town center of Pirna. As part of a PPP project, parts of the complex, which is listed as an historical building and archaeological landmark, underwent major renovations. Meanwhile, the district administrative headquarters of the Saxon Switzerland Eastern Ore Mountains were renovated and expanded. The project was concluded at the end of 2011. The upgraded, highly functional administrative building now provides 500 workstations and meets strict energy standards.

Our solutions: Optimum acoustics and a pleasant indoor climate
Our high-performance acoustic ceilings with integrated cooling system facilitate effective cooling and ensure optimum architectural acoustics. The ceiling elements consist of standard plasterboard panels with milled grooves in which tried-and-tested RAUTHERM S pipes are integrated.

  • Optimum indoor climate with no drafts or operating noise
  • Available in four different sizes, the active surfaces can be adapted to dimensions of the room.
