The new “Hochhaus Heuwaage” – an enhancement of the urban planning situation

A competition was held in 2017 to design the new building, which was won by Basel-based architects Miller & Maranta. The new free standing high-rise building will enhance the urban planning situation at Heuwaage and add value to the entire Steinenvorstadt district and the people of Basel. The ground floor, which is accessible from all sides and features a square area facing Steinenvorstadt, marks the start of the urban development of the Heuwaage area and the entire Birsig-Bogen. A square is being created on Steinenvorstadt that will encourage people to stop and enjoy the area.

Thanks to its distinctive design, the new pentagonal building blends into the city skyline, acting as a tall structure between the city centre and the surrounding neighbourhoods. The building's lattice-like structure allows for a certain degree of permeability, establishing a connection to the historic high points of the old town.

The master plan was approved by the cantonal government in 2020 and by the cantonal parliament in 2021. A building application for the replacement building was submitted in December 2022. Planning permission for the project was granted in March 2025. Preparations for construction then began.
