Mundsburg Office Tower

Hamburger Straße 1-15 in Hamburg


The Mundsburg in Hamburg-Uhlenhorst was built between 1969-1973. Since then, the lively building complex is marked by an attractive mix of offices, apartments and a shopping and entertainment center. The highly visible towers of Mundsburg are an integral part of Hamburg’s skyline.

In 2011/2012 alstria initiated a heavy-duty refurbishment of the 9,300 sqm Mundsburg Office  Tower, creating modern office space with contemporary furnishings and sustainable standards. After the renovation and modernisation the building offers more than just a productive and relaxed working atmosphere. It is also economically efficient and environmentally sustainable. Even before the start of the modernisation measures the global IT Company Atos Information Technology GmbH as the main tenant signed a long-term leasing contract for the building.

This refurbishment project is also part of alstria’s sustainability measures and has received a Silver pre-certificate award from the DGNB (German Sustainable Building Council or Deutsche Gesellschaft für nachhaltiges Bauen e.V.). The DGNB Silver pre-certificate demonstrates the project’s sustainability particularly with regard to space and energy efficiency as well as tenant comfort. As part of the modernisation the primary energy consumption of the building was reduced by about 80% leading to 875 tonnes less CO2 emissions per annum.
