Our Main building, building 60, is an outstanding building with an exceptional history. It has been designed by the architect Rudolf Steiger, founding member of the International Congresses of Modern Architecture (CIAM) and major protagonist of modern architecture in Switzerland, in collaboration with his son Peter Steiger.

In the Main building we find the formal influences of Le Corbusier, Auguste Perret and Frank Lloyd Wright with whom Peter Steiger also studied in Arizona in 1950-1951. It is unquestionably a major heritage item with an exceptional architectural value, but which has also suffered the wearing of time.It has been foreseen for a while to renovate the office tower of Building 60, and now it’s time to do it!.

The first phase of renovation is expected to start in 2023. A kick-off meeting has been held on May with all the stakeholders to set the detailed planning of the renovation and the complex relocation of people including the specific requirements linked to their role or day to day work (Directorate, Protocol office, Legal service and its sensitive archives…). The occupants of offices in B60 will be relocated to B42, and current B42 occupants will be relocated in the newly refurbished SCE Swing Space (B.653) and other EP offices across the site, for the whole duration of the works, with estimated completion by Q2 2025.

The renovation concerns exclusively the tower of offices of B60, therefore services on the ground floor of the main building (restaurant, bank, shop) and facilities near B60, such as the meeting rooms in Pas Perdus, will remain operational, though some nuisances (noise) will be unavoidable during specific phases of such complex work site.
