SIGNA is building STREAM, a modern office building with a height of around 90 metres and a gross floor area of around 50,000 square metres, directly next to the Mercedes-Benz Arena. In 2017, SIGNA acquired one of the last remaining undeveloped sites in the Mediaspree area in Berlin-Friedrichshain. The seller was the Anschutz Entertainment Group (AEG), which has taken the lead in developing this new urban district along the East Side Gallery. The STREAM will be built on the site at the corner of Tamara-Danz-Straße and Wanda-Kallenbach-Straße, based on designs by the GEWERS PUDEWILL architectural firm. The office building will accommodate a workforce of roughly 2,500. The main tenant will be the online fashion retailer Zalando. The construction work started at the beginning of 2019 and is projected to be completed by the end of 2021.
