At a fiery full council meeting tonight, 34 councillors voted in favour of removing a legal covenant protecting the land from being built on.
Six councillors - including four Conservatives - voted against the proposal.
The four rebels were Cllrs John Harrison, Brenda Wilson and Ian Leake, who represent Binfield with Warfield, and Cllr Robert Mclean, of Warfield Harvest Ride,
Both UKIP Cllrs - Shelagh Pile and Michael Sargeant both voted against the proposal, while Cllr Clifton Thompson was not present at the meeting.
Borough Mayor Cllr Jan Angell repeatedly threatened to halt the debate as angry residents chanted "disgrace" and "shame on you" at councillors.
A final decision on whether to remove the covenant will be taken by executive member for planning and transport, Cllr Chris Turrell, next month.
He abstained from voting.
