State Parliament Düsseldorf

Next Project
Located along the banks of the Rhine, the existing parliament building boasts a commanding presence in the heart of Düsseldorf. Due to the increasing number of political parties that must be accommodated within the parliamentary compound, the original 1980s building required significant expansion.

The winning competition entry, developed in collaboration with architects Schulz and Schulz and Transsolar KlimaEngineering, thoughtfully reflects the morphology of the existing structure. The design features four new volumes, suspended in the air and connected by light, airy bridges. With a minimal footprint, these new buildings create generous public space at ground level, allowing pedestrians to move freely between the nearby park and the river promenade.

This open flow is made possible by an efficient structural system, which supports large cantilevers by harnessing ring forces within the circular forms. The underside of the floating cylinders serves as the building’s "fifth façade." Here, we developed an organically ribbed slab that responds directly to the internal structural stresses, minimizing material usage. This design not only optimizes efficiency but also creates a refined and striking underside, evoking the intricate forms seen in Gothic architecture.
