Construction of ArcelorMittal's headquarters in Luxembourg.
Symbolising ArcelorMittal's loyal attachment to the Grand Duchy, the new world headquarters are being built in Luxembourg. The building's bold, innovative architectural design makes the most of recycled steel solutions.
The project was inspired by the shape and volume of the iron ore found in the red earth south of Luxembourg. The integration of a load-bearing steel façade will allow the building to “levitate”, conveying an image of lightness, elegance and transparency. The façades facing outwards are slightly sloping and the façades facing the atrium are slightly sloping. The façades facing outwards leave the metal framework visible, protected from the elements by the glass scales or by the atrium glass roof. The building, with its steel structure, enclosed by a glass roof and open to the city centre through a 50 m high façade, is built around a central atrium running the full height of the building.
The unstructured office floors can easily be divided into independent units, providing a high degree of flexibility.
The aim of this ambitious project is to create an iconic building, a benchmark in the Luxembourg City landscape. We designed the headquarters to be elegant, light and transparent, so as to blend harmoniously into this heterogeneous urban environment.
