With its new headquarters “HELIX”, the Luxembourg Post, one of the largest employers in the small state, is also setting a strong architectural statement for integration and solidarity. The centrepiece of the extraordinary new building, with 18,000 sqm of office space and room for around 850 employees, are the modern stringer stairs in the atrium that run upwards in the shape of a helix, and thus give their name to the headquarters, which opened in the capital in July 2023. The term “helix” exists in many languages and at Post Luxembourg, with its employees from over 50 different nations, it stands for a culture of openness and inclusion. As a zero-energy building with DGNB platinum certification (German Sustainable Building Council), the building was constructed according to the most advanced sustainability standards.
Over an impressive height of 30 metres, the modern stringer stairs made of flat steel connect the eight upper floors of the openly designed office complex and are imposing with their monumental dimensions and masterful execution. Rounded landing connections and the smooth-surfaced soffit cladding as sophisticated structural elements provide the modern stringer stairs with their sculptural character. In addition to the main staircase, a secondary staircase runs from the atrium directly to the second upper floor, giving the modern stringer stairs their dynamic basis. The entire system was realised with closed stringers and steel treads in a folding wooden design. Handrails made of fine solid wood are installed on each of the inner sides of the modern stringer stairs, as well as LED spotlights for the selective lighting system. In the field of premium staircase construction, MetallArt has achieved a masterpiece in planning, design and assembly with this modern stringer stairs.
