La Maison Olympique ("The Olympic House"), the CIO headquarter, in Lausanne Vidy, was designed by 3XN Architects, in partnership with Swiss architects IttenBrechbühl. It is located right next to Château de Vidy, the 3rd home of the CIO in Lausanne. The new building was inaugurated on June 23 2019, marking the 125th anniversary of the creation of the IOC in 1894. Shortly after its inauguration, a public visit was organised on Sep 13 and 14 2019.
The building received several certifications and awards for its renewable construction and energy usage. In particular over 1000 square meters of photovoltaic panels are installed on its roof.
The central wooden Unity Staircase connects the different levels of the building using 5 rings in reference to the iconic Olympic Rings. An Olive tree sculpture in the basements reminds the Greek roots of the Olympic Games.
