A planning application unanimously rejected by the council will now go to the Mayor of London for review.

The application by The Comer Group to put 1,350 new homes on the current North London Business Park was rejected by Barnet Council's planning committee on June 23, amidst concerns of over-development on the site due to its density and excessive height of proposed nine-storey tower blocks.

But now residents fear the decision could be overturned by the Mayor of London Sadiq Khan as it goes to review, despite having, as they believe, no significant changes made since the June committee meeting.

The review is part of protocol, as development proposals of such sizes will go to the Mayor's office regardless of committee decisions.

Martin Berliner, of the Weirdale Ashbourne Residents group (WAR), said: "The density of the plans and the height of the proposed blocks of flats and in our view the developers should be sent back to start again but this time engaging all interested parties.

"We have had unanimous council support and that of local MP Theresa Villiers, London Assembly Member for Barnet and Camden Andrew Dinmore, in addition to councillors Kathy Levine and Lisa Rutter, so we hope the Mayor's office will listen to the will of the people and reject this appeal and instruct the developers to start again with new plans."

Mr Berliner and other residents are calling on those who oppose the plans to contact Mayor Khan to put forward their views, so the developers will be forced to make changes to the plans.

Ms Villiers, MP for Chipping Barnet, said the tower blocks were out of keeping with the surrounding area and a big population increase would put pressure on roads and services.

She said: "Residents are up in arms over these plans, which are completely wrong for the location.

"I would urge the Mayor to listen to the unanimous verdict of the Barnet Council planning committee and reject the Comer Homes application for NLBP."

Mr Berliner also said that Cllr Lisa Rutter has asked that the Barnet Council planning officers' referral letter to Mayor Khan should state that, while residents are happy for extra housing, there are concerns over this proposal and the committee decision was unanimous across all political parties.

Cllr Rutter said: "I have been working closely with residents right from the start representing their concerns in this planning application.

"Whilst people understand the need for extra housing, they do not want tower blocks which are out of character for the surrounding neighbourhood.

"The danger now is that the application goes to appeal and could be passed by the Mayor of London."

Andrew Dismore AM has said he spoke to the City Hall planning officer, who has recommended in their report that Mayor Khan upholds Barnet Council's decision.

The final decision will be made known after the Mayor has considered all reports on August 23.

The Mayor's office did not wish to comment and Comer Homes has been contacted.
