OMA Completes Faceted Palais de Justice in Lille

The new courthouse features a hexagonal design inspired by historic French military fortifications.

1Architectural Design Concept

The Palais de Justice de Lille, designed by OMA, features a distinct hexagonal form. This six-sided structure is finished with a faceted facade lined in coloured glass. The design intentionally mimics the geometry of the adjacent star-shaped fortification, which was originally constructed in 1667 by the military engineer Sébastien Le Prestre de Vauban.

2Spatial Organization Strategy

The building is organized into three distinct volumes to manage court functions. A base plinth houses the major courtrooms, while a triangular central tower contains the minor courtrooms. Above these, a faceted ring of offices surrounds the tower, serving the dual purpose of workspace and light distribution throughout the interior of the complex.

3Material and Spatial Clarity

OMA utilized specific material expressions for each volume to ensure spatial clarity and orientation for visitors. Despite these differences, the interior spaces are unified through consistent light finishes and furnishings. The design team aimed to create a welcoming atmosphere that feels free of the intimidation often associated with traditional judicial architecture and legal institutions.

4Integration of Public Spaces

The project incorporates several outdoor areas distributed across the three primary volumes. These include a public plaza located at the ground level and a roof garden that provides views over the city. These spaces are intended to improve the building's relationship with the surrounding landscape and provide accessible areas for the public.

5Project Timeline and Commission

The Ministry of Justice commissioned this project to host Lille's high and district courts. OMA won the design competition for the courthouse in 2018. Although the project was originally scheduled for completion in 2023, the firm finalized the construction of the facility in 2024, marking a significant addition to the city's infrastructure.

6Broader Architectural Context

OMA, founded in 1975 in Rotterdam, continues to expand its global portfolio with diverse projects. Recent works include an affordable housing development in San Francisco and a pyramidal building in Hangzhou. These projects demonstrate the studio's ongoing focus on complex geometric forms and functional urban design across various international building typologies.

7Comparative Judicial Architecture

The Lille courthouse joins a series of modern legal facilities currently being developed globally. Other notable examples include a 10-storey federal courthouse by SOM in Florida and a Toronto courthouse by Renzo Piano, which emphasizes the values of modern justice institutions. These projects reflect a shift toward more transparent and accessible public architecture.

8Impact on Urban Landscape

The completion of this courthouse signifies a major investment in Lille's civic infrastructure. By positioning the building next to a historic fortification, OMA has created a dialogue between 17th-century military engineering and contemporary design. This project highlights the evolving requirements for judicial buildings that prioritize public accessibility and light-filled, modern interior environments.
