German firm gmp has won a competition to design a sports complex and a new urban layout in west Lausanne, Switzerland, on the shores of Lake Geneva.
A single circular building combines a UEFA football stadium for 13,000 spectators as well as a competition swimming pool, a boarding school and municipal sports administration.
The urban design for the adjoining areas provides residential and commercial units totalling 100,000 m² net floor space.
The roof area is used for harnessing renewable energy with the help of solar thermal and photovoltaic panels.
Construction is scheduled to start in 2016 and finish in 2019.
