Banque Postale set up its head office on Rue de Sèvres in Paris, on a block where the historic Caisse Nationale d'Epargne was built in 1886. The design seeks to impart coherence to the different styles and periods of the adjacent buildings. The 18th-century Hôtel Choiseul Praslin, the orderly 19th-century facades, and the glass window in the centre of the block are all respectfully highlighted whereas the new building boasts a contemporary design. By emphasising the identity of the buildings and their contrasts, the dialogue that is created between these different architectures, embellished with gardens, contributes to focusing attention on the distinctive aspects of each building while imparting coherence to the whole. This sustainable project, with its simple lines and its delicate silhouette, creates a new signature appearance for Banque Postale.
The headquarters of the Postal Bank is located in the heart of Paris, in the 6th arrondissement, on the corner of Rue de Sevres, Saint-Romain and Saint-Jean-Baptiste de la Salle. Between Luxembourg and the Invalides, this historic building contributes to the charm of one of the most popular areas on the left bank, near Saint-Germain-des-Pres, the Sorbonne and the Pantheon.
