Campaigners fighting the creation of a super-school in Wembley are urging the public to fight the plans.
Ark Academy already operates on a temporary basis at Wembley Park Sports Ground, at the junction of Bridge Road and Forty Avenue. Last month Brent Council submitted plans to make the site its permanent home - much to the dismay of campaigners.
The academy sponsor, education charity Ark Schools, is providing a confidential endowment, thought to be £1.5million, to help fund the new project alongside the Department for Children, Schools and Families.
Umbrella protest body Wembley Park Action Group (WPAG) - comprising teachers, residents and sports ground users - organised a meeting last week to urge people to lodge their official opposition to the scheme.
Among the speakers were Martin Francis, of Brent Green Party and Bill Greenshields, president of the National Union of Teachers.
WPAG chairwoman Jean Roberts said: "We're against having any school on Wembley Park Sports Ground. There's massive opposition from the local area against it."
Concerns range from the perceived privatisation of state education and questions about the motivation of Ark Schools, feared traffic problems, the operation of the school and pupils' wellbeing, and the loss of the current sports facilities and access to the proposed replacement.
Protesters argue the council's own school places survey showed that a new school is not needed in Wembley but further south.
Mrs Roberts said: "It's in totally the wrong place for a school. We're all united on that."
Once fully up and running, Ark Academy would be a mixed, nonselective, non-denominational school providing education from the age of three to 18 and housed in a purpose-built complex from September 2010.
There would be a nursery (60 children), a primary school (420) and a two-tier secondary school and sixth form (1,150) all operating from the same site but with four separate head-teachers serving under one principal, Delia Smith.
A spokeswoman for Ark Schools said: "We're very pleased to see the the application has been submitted.
"This is an important step towards a new academy for the children of Brent.
"We hope to create an environment that is pleasant for learning and teaching and provides a good resource for the local community.
"There are some concerns, misplaced, in our view, about a potential loss of amenities, but what we hope to do is provide enhanced sporting facilities."
Ark Academy became the charity's sixth operational school in London when two reception classes opened in temporary accommodation on the site on September 30, taking advantage of temporary planning permission earlier granted by Brent Council.
The permanent application could be decided by the authority's planning committee before Christmas.
WPAG's Mrs Roberts said: "We will be doing things before then to raise our profile and to encourage as many people as possible to oppose the academy. We're determined to defeat this ill thought-out and ill conceived plan."
A Brent Council spokeswoman said of ther plans: "The council has received the application but we haven't got the full set of accurate computer generated images of what the building will look like.
"We're not going to start full consultation on the plans until we get them."
