International Olympic Committee (IOC) staff have moved out of their old headquarters building in Vidy and will start work in their new temporary offices on the other side of Lausanne in Pully tomorrow.
Around 225 staff members vacated the Vidy headquarters on Friday (February 5) and worked at home today, as the last group moved out.
The new offices in Pully are close to the sites of the Olympic Museum and the Beau-Rivage Palace Hotel.
Most IOC events are due to take place there, although Executive Board meetings will take place at the Lausanne Palace Hotel.
All staff will start working in Pully tomorrow, except for those that are travelling to the Winter Youth Olympic Games in Lillehammer.
It follows a final month of meetings at Vidy, which included a meeting between IOC President Thomas Bach and Italian Prime Minister Matteo Renzi, as well as a crunch meeting with all summer International Federations on Rio 2016.
Deconstruction of the old building - the main IOC base since 1968 - will not happen until the spring, although the Château de Vidy building itself will remain as it has had listed status as a historical monument since 1971.
The new headquarters, to be built next to the current site, is due to be completed in 2020.
All 600 IOC employees should be housed on one site.
It will be known as Olympic House.
The 24,000 square metres plan is set to cost CHF 160 million (£107 million/$159 million/€137 million), with the design created by Copenhagen-based architecture firm 3XN.
The IOC plan to borrow up to 80 per cent of the cost and Ng Ser Miang, head of the organisation's Finance Commission, is currently in negotiations with three banks who have all offered an interest rate of less than one per cent.
A first stone was symbolically laid in December in a ceremony attended by President Thomas Bach and members of the organisation’s Executive Board during their final meeting of the year.
Bach presented a time capsule featuring five cylinders draped in the colours of the Olympic Rings, each of which includes a particular piece of history linked to the Olympic Movement.
