The footprint form of the building follows the specific contours of the building site, defined by two main roads in the western part of Luxembourg City. The former bank building has been demolished and replaced by a brand new construction. The building is designed around a central courtyard, which offers attractive views and ample light to the public areas, hallways and the restaurant.
The façade is specific to the project and consists of a combination of bright precast concrete pillars and panels. The aim of the strict vertical repetition is to install a new rhythm along the “Route d’Arlon” and allow a maximum of daylight in the office spaces while still offering a comfortable level of privacy and confidentiality. This repetition of the façade also permits a great modularity and flexibility in the organization and divisions of the office floors, without immediately showing these functions and subdivisions on the outside.
The interior design is bright and stripped-down. In the reception area, accesses to the elevators, restrooms and conference rooms have been gathered in an architectural box, cladded with perforated metal panels, and enhanced with an indirect LED lighting system.
Simple white walls divide the office areas all along the facade, while ceiling-high glass elements are arranged towards the inner corridors, to ensure sufficient natural light in the distribution areas. All the public spaces, foyers, seminar and conference areas and the staircases are paved with bright natural-stone tiles.
Anodized aluminium windows allow a natural ventilation of all the rooms in addition to the mechanical ventilation. An external, individually adjustable metallic sunscreen-system is integrated into the façade and guarantees sun protection. All exterior coverings (for example the inner courtyard and all the paths and stairs), analogous to the façade, are equipped with a bright concrete surface.
The technical concept pursues the objective of high performance with maximum comfort and minimization of energy consumption and energy losses. As a support heating and cooling loops are integrated into the plastered ceilings
