Adams Road Closure Extended to Prioritise Safety and Efficiency
To ensure the safe completion of the ongoing underground connection works for Building 777, the closure of Adams Road has been extended. While we understand this may cause some inconvenience, the additional time allows the project team to complete the work under safe conditions, particularly following the recent period of high temperatures, when certain activities…

Briand Bois Factory Visit
Earlier this week, the B777 project team visited Briand Bois’ timber production facilities along with representatives of the Architect, Engineer and Contractor. The visit gave a unique opportunity to inspect the timber elements currently being fabricated for the project, including glulam beams and columns, and CLT floor slabs (cross-laminated timber). Glulam and CLT are both…

Partial Closure of B867 Parking: Upgrades Underway for a Greener, More Sustainable Space
Closure of part of the parking area around building 867 is planned from the 18th May 2026 until the 4th September 2026 while we work on essential upgrades. The work, which will proceed in three phases to minimise disruption, will add over 150 spaces and transform the parking area into a more sustainable and green…

First Timber Beam Ceremony Marks Key Milestone for CERN’s Building 777
On Friday 24th April 2026, CERN celebrated a major milestone in the construction of Building 777 on the Prévessin site with the First Timber Beam Ceremony. While construction projects traditionally mark the laying of a foundation stone, Building 777 reflects a different approach. In line with its timber structure and strong environmental ambitions, the project…

Soar Over Progress: New Drone Footage Captures B777 Construction
New drone footage has been captured of the progress on the B777 construction site during a recent snowy day. The video, now available on the project website, offers a fresh perspective on the ongoing work, showcasing the steady progress being made—even in winter conditions. The aerial views highlight the scale of the project, from the…

Façade Prototype for Building 777 – From Vision to Reality
Today marks an important milestone for the Building 777 project at CERN; the full-scale façade prototype has arrived. The architects Henning Larsen (Denmark) and Redraw (France) will use the prototype produced by Briand Bois to verify its appearance and various technical aspects of its design, bringing us closer to realising a high-quality façade for Prévessin’s…

Building 777 Façade Passes Rigorous Laboratory Tests
Last Thursday, Luca attended a crucial milestone for CERN’s Building 777 project at the CSTB (Scientific and Technical Center for Buildings) in Champs-sur-Marne: the façade testing campaign. This phase of testing was essential, given that the unique façade design does not fall under standard French regulations. To ensure the building’s long-term reliability, a purpose-built facade…

Parking Upgrades at Building 867: Enhancing Sustainability and Accessibility
The B777 team is pleased to announce the start of essential upgrades to the parking area around Building 867. As part of this project, several trees—primarily older or lower-quality specimens—will be carefully removed to make way for a more modern, sustainable, and user-friendly parking facility. The work to remove the trees is planned to start…
