Now Kier’s project team will submit a planning application to the London Borough of Ealing this month.
Construction of North Ealing Church of England Academy is expected to begin in October, with the main building being complete for the first intake of pupils in September 2013.
Internal fit-out works will continue until April 2014.
The school will teach 1,200 11 to 16-year-olds, a sixth form with places for 250 students and a centre for children with special educational needs.
Under current proposals, the local community will also be able to use the school’s facilities, including its full size sports pitches, floodlit hard playing surfaces, indoor sports hall and activity studio.
