A Uniting Structure at the Heart of Modern-Day Paris
The 23,000㎡ Le Monde Group Headquarters is built at the intersection of the old, historic parts of the French capital, and the more modern districts on the Rive Gauche. A previously industrialized area with railway tracks, the district has experienced a mass development since the beginning of the 1990’s under one of the most comprehensive urban developments of the French capital since 18th century Haussmannization. Today, the district has continued to develop as a high-density commercial and business district.

The building’s pixelated outer skin is composed of more than 20,000 pixelated glass elements in a strictly organized pattern with 772 possible configurations, that give the building a sheer appearance that shifts with the changing weather and light conditions. Each glass element represents one distinct pixel classified on an opacity scale ranging from transparent to fully opaque depending on its placement, allowing for the best views from the building as well as a maximum of daylight penetration. This highly sophisticated pattern references the printed letters of newspapers and magazines and makes up a text-like pattern that can be read more clearly when the 10 000 m2 facade is seen from afar.

Spanning 80 meters from one side to another, the building is a response to the conditions and challenges of the site: Acquired by the Le Monde Group in 2014, the site is situated just above the railways and platforms of the Gare d’Austerlitz which makes the creation of a technical basement impossible. The first challenge, therefore, was to construct a building where the entire technical system of the building would be cleverly incorporated into the structure of the building itself. The second challenge was that the site could only carry a specific amount of weight, and only on the two extremities of the site. As the middle section was not planned to hold the weight of a building, the client’s initial brief was to create two buildings on the parts of the site that were buildable.

Snøhetta和SRA Architectes对以上挑战作出的回应是，建造一个连接性的钢结构，将位于场地两端的两个单元整合起来——对于一座重量超过埃菲尔铁塔的建筑而言，这无疑带来了巨大的工程挑战。但与此同时，这也是一项必须完成的任务，因为只有统一的建筑才能够创造出动态且活跃的环境，才能够将Le Monde集团旗下的各个部门连接为一个整体。
Snøhetta and SRA’s response to these challenges was to work on the idea of merging the two units together through a bridging structure of steel that would literally leapfrog from one side of the site to the other: a highly demanding engineering task for a building that weighs more than the Eiffel Tower. Nonetheless, it was a necessary one: only a unified building would create the dynamic environment needed to unite the different magazine and newspaper titles of the Le Monde Group.

A Walk Through the Building
The journey through the Le Monde Group Headquarters commences at ground level where visitors are greeted by a broad public plaza with integrated vegetation. The plaza invites passersby to linger and interact while also creating connections to the cityscape on each side of the building. From 2021, this physical connection will be further enhanced with the introduction of a new bridge that will spanning across the neighboring railways of the Gare d’Austerlitz.

New retail spaces also help activate a dynamic public realm. Situated below the warmly lit arch of the building, custom designed concrete benches offer refuge from the activity of the busy surrounding area. The site further encourages diverse transit modes and greener mobility alternatives with more than 300 bicycle parking slots and through its immediate proximity to neighboring train station.

The materiality of the plaza is predominated by concrete with clear references to the urban context of the building. The concrete environment creates a sense of continuity and consistency, as if parts of the ground were gently peeled back and fused into the arching roof soaring above the plaza. Cast in in-situ concrete, the arch above the plaza is carefully hand-treated to create a textured finish.

The concrete plaza and elements from the façade continue inside the building. The building’s wayfinding, which is also developed by Snøhetta, is inspired by the glazed facade of the building and adorned with classic typewriter typography. This custom wayfinding guides visitors and staff effortlessly through the building.

The Le Monde Group Headquarters can be accessed from the two extremities of the building, one of them public, leading to food and retail services and providing access to a two-story auditorium. The other entry leads to a reception area for parts of the building which are only accessible to the Le Monde Group. The reception area reveals itself as a white canvas framed by a grey-scaled concrete terrazzo flooring that evokes the plaza outside.
Two large amphitheater stairs in each entry lead up to the third level of the building, providing an unformal meeting space for staff and visitors. The stairs mark a physical continuity with the building’s arching middle-section, as if the stairs were mounted on top of it. The stairs provide access to the auditorium through an open reception area, well-suited for either conferences or receptions. The floor also comprises a staff cafeteria and restaurant including back office functions and meeting rooms.

From the third to the eight floors, the building offers high-quality, expansive open office spaces with a ceiling-integrated heating, ventilation and lighting system assuring the building offers maximum layout flexibility. With its floor-to-ceiling windows, and views overlooking the Seine and the surrounding city of Paris, the offices offer a bright and spacious backdrop for the thousands of employees and journalists of the Le Monde Group. Floors second also feature amenities such as a library, a staff restaurant and an analogue archive dedicated to the Le Monde Group.

From the fifth to the sixth floor, one finds the office spaces dedicated to the Le Monde newsgroup. Just like the office floors below, the Le Monde offices are organized as an open space, while also offering a diversity of flexible workspaces that integrate over 100 private work areas and over forty meeting rooms for group collaboration. The floors are connected by a double-spiraling staircase that opens the central part of the two levels. The staircase ties the newsroom together, breaking down artificial collaboration barriers and securing that information may be shared easily across the entire newsroom.

Finally, the top level of the building leads out to an open-air terrace which is accessible from both sides of the building. Framed by vegetation, the terrace creates beautiful views overlooking the surrounding cityscape and the Seine.
