Striking residential building Rennwegdreieck, Freiburg
Project information
Between May and November 2022, we carried out a comprehensive renovation of a circular water chamber with a capacity of 1,500 m³ for Stadtwerke Bad Nauheim GmbH.

This was followed by the application of a new cement-bound coating to the interior surfaces, with 345 m² of ceiling space finished in white, 440 m² of wall and column surfaces in blue, and 345 m² of floor space in gray, all professionally executed.
