The project for the new headquarters office building of Ferriere Nord was developed to bring together all Group functions within a single facility. The centralisation of all company departments aimed to improve operational efficiency, optimise internal organisation, and provide spaces tailored to the specific needs of each office.
The project placed particular emphasis on user comfort, ensuring high standards of indoor climate, natural lighting, and acoustic performance in order to create a better working environment.
The building is organised over three operational floors, with a fourth executive and representative level, all connected through a central entrance hall. A semi-basement level was also constructed to accommodate technical rooms, archives, and a six-car garage.
The structure consists of two rectangular volumes arranged at a 90-degree angle and rises over three to four above-ground floors, with the possibility of future vertical expansion on the main wing. The ground floor includes a 70-seat auditorium/conference hall and offices requiring a higher degree of interaction with external visitors.
The office layout follows a T-shaped configuration, with one wing perpendicular to the road and the other parallel to it, organised around a triple-height central atrium. Offices, both enclosed and open-plan, are distributed along the perimeter and benefit from natural light and ventilation.
The building includes internal circulation stairs as well as external emergency staircases positioned at the ends of the two wings.
The façade concept was inspired by the company’s core product — steel bars — reflecting the identity of a leading steel manufacturer. Layered one above the other, these elements generated the architectural language of the building, with staggered volumes creating a dynamic and contemporary appearance.
The rear façade is composed of light-coloured prefabricated concrete panels, contrasted by dark painted metal louvers enclosing the entrance hall and external stair cores. A continuous ribbon window system alternates with the opaque sections and is made of thermally broken aluminium frames.
The structural solution consists of reinforced concrete slabs with 25 cm solid floor plates supported by reinforced concrete columns and shear walls arranged on a 6 × 7.5 m structural grid. At ground-floor level, the structure rests on a 50 cm slab supported by a pendulum-type seismic isolation system, providing a high level of earthquake protection while eliminating the need for structural expansion joints despite the irregular geometry of the building.
