The new POST Headquarters is situated in a quite particular urban environment. It is located in the densest district of Luxembourg, opposite the city's main traffic hub, and is characterised by Haussmannian architecture with massive natural stone facades. This new building had to, therefore, be a link between the contemporary and the history. On one side the CNS new Headquarters participates in the revaluation of the district, and on the other, the historic Accinauto building ends the Haussmannian route of the Bourbon Plateau, with its listed façades to be preserved.
