Post Tower

Perfect synthesis of transparency, functionality and component design

The headquarter of the Deutsche Post in Bonn/Germany is a central landmark along the river Rhine. The tower, which in plan view is approx. 85 metres long by 40 metres wide, consists of two segments of a circle offset against each other; with its 41 stories it reaches a height of 162 metres.

The tower is enveloped by means of a second-skin facade. This allows windows to be opened even on the upper levels and forms an integral part of the energy concept of the building which is based on minimal energy inputs.

In 2014, the Post Tower received the “10 Year Award” from the Council on Tall Buildings and Urban Habitat (CTBUH). The 10 Year Award recognizes proven value and performance in a tall building, across one or more of a wide range of criteria, 10 years after a building has been completed.
