The Vattenfall building, formerly the HEW building, is a building complex completed in 1969 in Hamburg, Germany. The 153 m long and 44 m high building is constructed on a reinforced concrete skeleton and consistently positioned with its longitudinal axis in a north-south direction. The four buildings, which are slightly offset from one another, have different lengths but are all 12 stories high. The façade shows a light-dark contrast between the bronzed glass, which absorbs almost 70% of the sunlight, and the stone clad side walls. These side walls were originally clad with Norwegian limestone which, however, weathered heavily over time and was replaced by light-colored Indian gneiss.
Arne Jacobsen tried to give the building, which was greatly reduced in form to pure function, a harmonious look. In order to achieve this, he took care of the drafts of many details so that he could create a well-proportioned total work of art.
