Hager Group is a globally active manufacturer of electrical installations. The German-French family business, with headquarters in Alsace and Saarland, has been producing and researching across country borders since the 1950s. Today, the company operates in a global market with over 11,000 employees at 23 international locations, while at the same time staying true to its roots.

The corporate campus in Obernai, Alsace, is the company's largest production site and flagship. As it adapts to changing production and working conditions, it is in a constant state of transformation. Sauerbruch Hutton has been shaping this evolution since its winning competition entry for the Hager Forum in 2012 and has continued contributing to the expansion and reorganisation of the campus with a total of four projects.

The Hager Forum was created as a spatial and conceptual centre on the campus, a communicative place where ideas, information and talents come together. Since 2015 the campus has hosted symposia, workshops and training courses for in-house employees and guests from all over the world. Under an elegant cantilevered roof lies a weather-protected public forecourt, forming the prelude to the company premises and crossing point for all paths across campus. With its unpretentious appearance and robust logic, the Hager Forum integrates itself into the family of surrounding buildings while establishing a new family of materials with its metal and glass façade.

In direct visual proximity to the new Hager Forum's forecourt, the old Forum building was fundamentally redesigned, refurbished and, together with two other existing buildings from the 1980s, supplemented by a new building for the Executive Board. Its compact, amorphous form defines an additional square on the campus. Continuing the outdoor space, a light-filled foyer guides visitors to the “Link”, a central space that serves as an informal hub among staff. Through an elegant steel staircase, bridges and walkways, this space connects the four building sections from different periods of the company's history, thus forming a link between tradition and progress.

The extension of the Production Building for modular electrical safety devices combines the two predominant material families of exposed concrete and metal, thus establishing formal continuity on the campus. The program of the new building extends over two floors. The production area on the ground floor is clad with perforated metal cassettes, while the offices on the first floor are clearly recognisable by a continuous ribbon window. Generous green patios structure the open-plan office areas and provide additional meeting spaces.

Located directly at the entrance to the company grounds, the Taranis project marks the latest building block of the Hager Campus. An extension of the existing Research & Development building, it acts as a showroom, allowing customers and visitors to observe and run testing procedures. With its monolithic volumetric form, the building responds to the prominent location and the inward-facing program. The metal façade adopts the materiality of the Forum, yet reinterprets it in texture and detailing.
