The Königstein im Taunus Kurbad has been a listed building since 2013. The spa bath was planned by the architects Geier + Geier (today Völlger Architekten) in collaboration with the Stuttgart artist Otto Herbert Hajek. Now 4a Architekten have been selected to renovate the striking structure from the 1970s. "With the contract for the renovation of the spa, an exciting challenge is waiting for us in the new year. After numerous renovation projects, we will now expand our know-how in the field of monument protection with the Kurbad, " says Martin Reimer, managing partner of 4a Architekten.
