The proposal will see the capacity increase to 1,770 pupils and will include a six-lane, 25m swimming pool and changing facilities. The existing sports hall and tented sports hall will be retained.
The plans have been recommended for a approval at a meeting of Peterborough City Council’s Planning and Environmental Protection Committee on Tuesday.
The development involves refurbishing existing buildings and constructing new facilities, including a hall, classrooms and other teaching facilities in a three-storey block.
Once the new building is up-and-running, most of the old one will be knocked down to make way for sports facilities, including two football pitches.
Funding for a complete rebuild was withdrawn when the Building Schools for the Future programme was scrapped last year.
Instead, the council agreed to provide £36.6m for a scaled down rebuild of both the college and Nene Park Academy, formerly known as Orton Longueville School, also due to be rebuilt under the council BSF bid.
Acting principal at Stanground College, Ali Story, said: “It’s been an eventful period, but we are near the end of a very long road now.
“We’ve been through so many obstacles and because of that I feel cautious but really optimistic at the same time. Come Tuesday I hope we’ll be celebrating and looking forward to this fantastic new development.”
