The designs for the 1,350-pupil school, which will see the existing north and south campuses merging into a single facility, will see the firm build eight sports pitches, a theatre and science laboratories built.
Kier Northern will consult the academy and community to fully develop the detail of the designs before work starts later this year for completion in 2012.
The new teaching facility will also be fitted with drama and performance areas, a creative learning centre, media centre and 550-seat theatre.
Academy principal Kevin McDermott said: “The new building will be more than a school, it will be an icon for our community; it will enable our students to live their dreams and it will ensure our talented staff can best support outstanding teaching and learning. Our students, staff and community deserve this.”
Kier Northern managing director, Nigel Brook, added: “This is an important project for us and we recognise the significance of creating the very best learning environment for the young people of Ellesmere Port.”
