VoltAir is a pulsating urban building block for new office spaces at Alexanderplatz in the heart of Berlin. The appearance of the building is defined by stacked, two-story glass cubes. A horizontal setback between the facade boxes at the level of the adjacent S-Bahn viaduct, connects the building with the cityscape. Thanks to its holistic design and visibility in the urban space at one of Berlin's most bustling locations, VoltAir has become the new home for innovative companies.
