1 parteizentraleThe new CDU party headquarters in Berlin is enveloped by a spacious winter garden
providing noise prevention and climate control.

In contrast  to the glass envelope which strictly follows the boundaries of the adjacent building , the dynamics of the wedge-shaped office complex can fully unfold inside.  This façade is rendered highly transparent by separation of the glass layer  from the main steel structure.

Space frame columns  and roof girders are made of welded steel sheet. The cross  members of the façade owe their filigree appearance to the fact that they are connected to the columns by tension rods fixed at their  centres. Generously dimensioned openings for air-supply and exhaust  create a comfortable climate inside.
