Stiftung Preußischer Kulturbesitz
The extension to the Berliner Philharmonie around the Kammermusiksaal and the "Staatliche Institut für Musikforschung Preußischer Kulturbesitz mit Musikinstrumentemuseum" (Institute for Music Research and Musical Instrument Museum, Prussian Cultural Heritage Foundation) developed under the supervision of his office partner Edgar Wisniewski, who took over the office after Scharoun's death. During the 1980s, the facade of the Philharmonic Concert Halls was provided with a cladding of gold-anodized aluminum plates; originally it was a white and ocher painted concrete facade.
