A rival bid has been submitted to open a new school at the former Holyport Manor site.
Developer Michael Shanly and his partner Daniela Szmigielska put in an offer last week to buy the Ascot Road site from the council.
Their aim, along with fellow bid directors Emma and Nigel Barklem, is to open Beech Lodge School at the site in September.
The news comes two weeks after Cllr Simon Dudley announced he was part of a group bidding for £20m of Government funding to set up Holyport Free School on the site.
Beech Lodge would be an independent, fee-paying school, specialising in educating children who struggle in mainstream schools.
Daniela and Michael are adoptive, step and birth parents to seven children and Emma and Nigel are parents to four.
Daniela, 47, said: "We both have children who struggle at school and feel there is a big gap in the education system for this type of school."
There would be space for 160 children aged of five to 16 at the school.
It would be not-for-profit and money to buy and convert the site would come from the Shanly Charitable Trust. If the bid for Holyport Manor is unsuccessful the group will look for another site.
