1 amt_berlinThe new German Foreign Office, located in the centre of Berlin, consists of an old building and a new extension which is adapted to the proportions of the historical structure. This ensemble fuses the past and the future to create a grand visual impact and is deemed to be one of the most interesting office buildings in town.

The office complex surrounds a rectangular atrium on three sides, while the fourth side is closed off with a glazed facade rising to the full height of the building.
The glazed roof rests on a grid of six main girders running parallel to the facade. This grid supports a secondary structure, a grid of rectangles forming individual cable braced barrel vaults, on which the panels of laminated safety glass are installed.

The glazed facade has an almost invisible supporting framework of pre-stressed steel cables, some of them additionally braced by steel rods.
