Bundestag Office Building Unter den Linden 50
The former GDR Ministry of Foreign Trade building was converted by architect Alexander Kolbe into an office block for members of the Bundestag, the Lower House of the German Parliament.
The building, which measures 100 by 100 metres, includes 450 offices, 19 board rooms and four shops, and takes up an entire block.
Its external appearance has changed radically in recent years. The front of the building has been faced with Roman travertine, whose yellowish-brown hue harmonises with the tone of the Embassy of the Russian Federation across the street.
The interior courtyard designed by Klaus Rinke contains a birch tree grove and the vast "Sunbeam" sculpture that marginally exceeds the height of the building itself.
