CERN Building 777
CERN is constructing its new Building 777 (B777) on the Prévessin campus, at the edge of a dense forest. Scheduled for delivery in Q4 2027, this timber structure will bring together modern offices, a restaurant, laboratories, and more than 500 working stations.
Designed to foster collaboration, community, and well-being, B777 embodies CERN’s commitment to sustainable, low-carbon design.

Natural Meeting Place: Enabling Mobility and Promoting Collaboration
The building will form the social epicenter of campus life, fostering collaboration and camaraderie among the CERN community. A new plaza connects park areas, forest areas and the warm interior of the building, in the quadruple height atrium and informal working and lounge areas. Workplaces on every level are positioned in close proximity to attractive outdoor areas and nature.
The Vision
A campus which surpasses the industrial and laboratory context, creating a happy, healthy workspace that harmonizes with the natural environment. Mindful of embodied and operational carbon impacts, biogenic materials and low-carbon design are prioritized throughout the building.
The Building: Community Generator
A research community hub housing office, state-of-the-art laboratories, and inviting meeting areas for the Accelerator & Technology Sector (ATS). A new restaurant will serve as a vibrant social hub, catering to the entire Prévessin Site.
