The new office building for the European Investment Bank in Luxembourg was built to a design by Dusseldorf-based architect Christoph Ingenhoven. The particular features of this building are its cable façades as well as the curving glass envelope spanning over the whole structure. This article provides a detailed description of the steel-and-glass structures to the façades and barrel vault, which are the main elements determining the building’s appearance. Particular attention is paid to the very high safety standards applied to all structures. Thanks to a sophisticated combination of various loadbearing elements it was possible to unite maximum transparency with remarkable robustness.
