The new Justizzentrum Köln is conceived as an open and civic campus, carefully embedded between the urban fabric of Cologne and the adjacent green belt. Rather than a monolithic judicial complex, the project is articulated as an ensemble of distinct yet related buildings set within a park-like landscape. This strategy reduces the perceived scale of the program and invites public approach from all sides, lowering institutional thresholds and strengthening the relationship with the surrounding city.

Urban continuity is reinforced through the extension of the green belt’s pedestrian network into the site, weaving between the buildings and connecting existing structures to the landscape. A clear spatial hierarchy is established along the Boulevard of Justice, where generous, transparent foyers open directly onto public space, ensuring legibility, orientation, and accessibility.

Architecturally, the buildings share a common structural and material language while expressing their individual functions through subtle façade variations. The façades are composed of two-storey modules combining a robust outer layer—made of recycled concrete or natural stone—with a warm inner core of timber. This dialogue between solidity and warmth reflects both the institutional role and the civic ambition of the project.

Sustainability is embedded in the architecture through flexible structural grids, low-tech environmental strategies, shaded façades, green roofs, and the integration of renewable materials, ensuring long-term adaptability and durability.
