The new 10,000m 2school - designed to feel like a 'high-quality hotel' - will feature a five storey tower and a central, glass-roofed atrium.
This space will house the school's new library, which is to be built on columns above new exhibition and performance areas.
Funded through the government's Building Schools for the Future Scheme, the rest of the building will be split into five two-storey blocks and will include a new sports facility, science and technology wing and a studio for gym or dance.
Explaining the scheme, GWK's director of development Graham Cawthorn said: 'The design of the building is very innovative.
'It will be a cross between a high-quality hotel and the sort of buildings you would see in a modern business park.
'It will also have facilities for the community to use, such as the sports hall and some of the computer blocks.
He added: 'The staff and pupils, together with the Wrekenton community, can at last look forward to a new state-of-the-art school.'
The school in Whitehouse Lane is expected to accommodate about 1,200 students aged from 11 to 18.
Once complete the existing St Edmund Campion school will be demolished.
