Campaigners will make a last-ditch attempt to save a green at the “heart of the community” before councillors decide on its fate tonight.
Opponents of the Cricklewood Regeneration Project will petition Barnet Borough Council to listen to their pleas before approving the controversial planning application.
If successful, the well-loved Cricklewood Green Space, opposite B&Q, will be destroyed to make way for new homes.
The plans form part of the £4billion Brent Cross regeneration project which was granted planning permission three years ago, but campaigners are urging councillors to make a U-turn.
Minor changes to the existing application have sparked a new meeting and application which will take place at Hendon Town Hall, in The Burroughs, at 7pm this evening.
Protestor Lia Colacicco said: “We are asking councillors to do the responsible thing and not to cave in to them, and demand something better for Barnet.
“Our main concern is with the Cricklewood Green - it’s at the heart of the community. We want them to do what’s best for the people of Barnet who have elected them.”
Amendments include building a new pedestrian and cycle crossing over the Living Bridge, changing the layout of streets and moving the bus stop have been added to the original application.
Ms Colacicco added the plans are “old-fashioned” and campaigners will also be flagging up issues with pollution.
Meeting rules usually dictate that only two people can speak - but ten will be allowed to give their views due to the size of the application.
It is the biggest application in the history of north west London, with more than 7,500 homes planned.
More than 27,00 jobs will also be created in the huge new town centre with retail, dining, leisure and community facilities.
