Renovation work on Building C5 2 nearing completion

During a guided tour on Friday, 10 April 2026, Torsten Lang, the responsible State Secretary at the Ministry of Construction, provided an insight into the extensively renovated building. Flexible and versatile office units have been created based on the structuralist architectural style of the 1960s. At the same time, the building’s optimised façade, its balanced proportion of glazing, modern technical equipment and a photovoltaic system ensure a significant reduction in energy consumption.

By retaining the existing concrete structure, existing resources could be reused, thereby greatly reducing CO₂ emissions. The building’s architectural identity has also been preserved: The distinctive exterior appearance has been retained, as have characteristic elements in the interior, such as in the foyer and stairwells.

The state has invested around 30.4 million euros in the modernization of the existing building. In the future, it will be used as a dedicated office building for the Faculty of Humanities; comprising 6,900 m² of modern office space.
