A place for digital innovation was desired: La Poste wanted to bring its IT departments together in a new competence centre to promote synergies between teams and drive forward the digital transformation of the postal service. It also wanted attract young talent within the 1.200 members of the staff. Communication within the company is at the heart of its corporate purpose, which has been efficiently implemented with the architecture of Baumschlager Eberle Architekten. Today, the Maison de l'Innovation is a building that blends harmoniously and confidently into the surrounding urban landscape. Communication is also cultivated inside. From the large, covered courtyard to the corridors and open terraces, this theme is cultivated at various levels of accessibility.

The building echoes the monumental perspective of Boulevard Vincent Gâche and, with its slightly sloping roofline, adds a confident accent to the cityscape. Arched elements, which refer to the historic Vendée bridges over the Loire, serve as an architectural leitmotif. This local anchoring takes various forms: on the ground floor, the arch forms a two-storey portico that marks the main entrance, while on the upper floors, inverted arches frame the loggias. The reference to the city's past and its contemporary interpretation generates a high degree of recognition in the public space. However, the building does more than that: it is surrounded by green spaces, and the building surfaces are also greened, creating interfaces between the city, nature, water and people.
Sustainability is rooted in architecture. Neutral-use spaces enable flexible adaptation to changing working conditions. This makes the building durable and sustainable. Conventional air conditioning has been dispensed with in favour of passive strategies. The depth of the façade enables passive control of solar radiation. In the summer months, innovative cooling via air circulators provides additional comfort. The building's sustainability qualities have been confirmed by several certifications. In addition to E2C1 certification for energy efficiency and CO₂ reduction, the project received the HQE certificate at the ‘Excellent’ level. It has been awarded the OsmoZ certificate for optimising building quality and interior design and the BiodiverCity label for promoting biodiversity.
The special quality of the project lies in its complexity of content, which has been implemented in a homogeneous manner. It meets the client's requirements for different levels of communication. The architecture makes a fundamental contribution to longevity through its neutrality of use. Biodiversity is not an empty word: urban agriculture and a honey meadow on the roof, as well as nesting places, testify to a concept that is consistent. The connection between old and new is also consistent, thanks to the leitmotif of the segmental arch. In addition, the design picks up on the special qualities of French architecture: the elegance of the building's contours and the grand gesture. This is evident in the urban layout and the large, clear inner courtyard.
Creating optimal working conditions for our employees was a major concern for us. So was the construction of a building using contemporary sustainable building methods. The Maison de l’Innovation is also intended to make a positive contribution to the city of Nantes on behalf of our company.
