Designs for a new 300,000sq m (3,229 sq ft) mixed-use sports complex in Nizhny Novgorod, Russia, have been unveiled as part of the country's preparations for the 2014 Sochi Winter Olympics.

The state-funded development, designed by UK-based Wilkinson Eyre Architects, will be used as a training facility and reserve site for the Olympics and will include five Olympic ski jumps encased in a 125m-high structure with spectator grandstands. There will also be a 22,000sq m indoor ski bowl, an indoor skating rink, an aqua park and a Nordic competition cross country ski course as well as a five-star hotel and apartments linked by a shopping centre. Matthew Priestman of Wilkinson Eyre Architects, said: "Nizhny Novgorod was once a famous ski-jump centre and this heritage is celebrated by placing the ski jump as an iconic form at the heart of the scheme, with the additional elements of the complex designed as low lying forms along the banks of the river.’

An outline planning application for the development is expected to be submitted in April.
