A number of banks, government agencies and European institutions are located on the Kirchberg-Plateau in the north-east of the city of Luxembourg, where the plaza of the new Ernst & Young headquarters opens up towards the wide Avenue John F. Kennedy. On two sides this generous public entrance is flanked by cafés and shops. The brief was to design an attractive and cost-effective roof that provides a horizontal edging towards the road, and an extraordinary low construction height to prevent it from projecting too far above the first floor.
The structure comprises a two-way spanned dome-like steel grid over a diamond-shaped footprint. It features suspension cables and a roof cladding of flat quadrangular glass panes. All four sides of the roof intersect with tilted glass panes, so that the eaves are continuously horizontal. They run in line with the height of the eaves on the wing buildings. Arranged under every second arch in transverse direction, filigree tension members above the horizontal cables support the grid structure and facilitate the exceptionally low rise.
