Currently Europe’s largest inner-city building site, Potsdamer Platz in Berlin is being redeveloped to make it, once again, a pulsating cosmopolitan center. A major part of this development is the Sony Center which covers an area of 86,614 sq. ft. and includes the company’s new European headquarters. With large areas of glazing and huge numbers of computer screens, control of the light through the windows into the offices was a vital consideration in the design of the headquarters building. The designer uses Levolux specialty venetian blinds.
