With the R4 building in the second row behind the Z building on the Konsequenz, Bielefeld University is creating future office space for the Medical School OWL. A special feature of the building is the highest energy standard of the university's new buildings to date: the R4 building will meet the passive house standard.
The R4 building has a total area of 3732 square metres (usable area 1-6) and will be equipped, among other things, with a green roof and a photovoltaic system. The general contractor commissioned is the construction company Kleusberg, which has already constructed Building Z in 2018 and the extension Z2 for Bielefeld University in 2020.
Construction started in the thrid quarter of 2023, the building was completed in May 2025.
