Construction has officially started on ArcelorMittal’s new global headquarters, ArcelorMittal Kirchberg. During the event a steel beam, made with ArcelorMittal’s XCarb® recycled and renewably produced steel, was lowered into place to signal the start of construction.
Designed by Wilmotte et Associés, ArcelorMittal’s new headquarters, ArcelorMittal Kirchberg is a showcase for the use of steel in sustainable construction. The building, which will be commissioned in Q1 2026, incorporates 10,000 tonnes of ArcelorMittal steel, mainly produced in Luxembourg from recycled steel. The beams are made from XCarb® recycled and renewably produced steel, representing a saving of more than 10 tonnes of CO2 per beam. In this way, ArcelorMittal Kirchberg serves as an exemplar of how low carbon-emissions steel can be used in construction.
The building will have a crystal-like appearance, which spirals outwards and opens onto the city through a façade covered in plants. In addition, the new headquarters offers flexible, modular working and living spaces to ensure a great working environment for employees. The building will fully be aligned with three major environmental labels: BREEAM (outstanding level), DGNB (Platinum level) and WELL (Gold level).
