Commissioned by the Ministry of Justice, the structure serves both high and district court functions. The project replaces older facilities, aiming to modernize the city's judicial infrastructure through a distinct, contemporary architectural expression. ## Historical Context and Site The courthouse occupies a verdant site directly adjacent to a star-shaped fortification originally built in 1667 by Sébastien Le Prestre de Vauban. OMA designed the building's pointy, hexagonal form specifically to mimic the geometry of this historic military structure, creating a dialogue between modern judicial architecture and traditional French defensive heritage. ## Structural Volume Distribution The building is organized into three distinct volumes, all accessible via a shared public base. The first volume serves as a plinth housing major courtrooms, while a central triangular tower contains minor courtrooms. A faceted ring of offices sits above, designed to maximize natural light penetration throughout the entire complex interior. ## Materiality and Spatial Clarity Each of the three volumes features a unique material expression and spatial character, intended to provide clarity and orientation for visitors. Despite these differences, the interior spaces are unified by light finishes and furnishings. OMA aimed to create an environment that feels welcoming and intentionally free of traditional judicial intimidation. ## Integration of Outdoor Spaces The project incorporates several outdoor areas distributed across its three main volumes to enhance user experience. These include a public plaza located at the ground level and a roof garden that provides views over the city of Lille. These spaces serve to soften the building's presence within the surrounding landscape. ## Timeline and Development History OMA, founded in 1975 in Rotterdam, secured the commission after winning a design competition in 2018. Although the project was originally scheduled for completion in 2023, the final delivery occurred in 2024. This timeline reflects the complexities inherent in constructing large-scale public infrastructure projects within sensitive historic urban environments. ## Broader Architectural Portfolio This courthouse follows other recent OMA projects, including an affordable housing development in San Francisco and a pyramidal building in Hangzhou. The studio continues to explore complex geometries across diverse sectors. Their work often emphasizes functional clarity, as seen in the deliberate separation of courtroom volumes within this specific French judicial project. ## Industry Trends in Courthouses Modern judicial architecture is increasingly shifting toward transparency and accessibility, moving away from imposing, fortress-like designs. Similar to Renzo Piano’s Toronto courthouse project, the Lille facility prioritizes light and public engagement. These designs reflect a global trend where institutional buildings aim to represent modern values through open, light-filled, and welcoming spatial configurations. ## Sources covering this story - https://www.dezeen.com/2026/10/19/oma-palais-de-justice-de-lille/ — --- _Summary written by Brifing from the original reporting.
