Private brewery Ketterer Pforzheim
The flagship of the small Braumanufaktur Ketterer in Pforzheim, the historic castle cellar, is the center of quality economic culture in the city. In 2015 was scheduled the refurbishment of the guest rooms with a barrel vault. An uncommon task for architects, which, in addition to the design considerations, also poses a challenge to room acoustics. The digitally printed and specifically positioned wall absorbers improve the acoustic conditions without denying the character of a vault.
