Plans to open a private school in Fortune Green have sparked concerns that the influx of cars will create “traffic chaos”.

Westminster’s Abercorn School, which takes pupils aged two-and-a-half to 13-years-old, has made public proposals to open a small school at Alfred Court in Fortune Green Road, which is also known as the Sager Building.

The school, which charges up to £5,250 per term, plans to use the building’s vacant ground floor to teach seven to 13-year-olds.

But Andrew Saywell, of West Hampstead and Fortune Green Conservatives, said residents are worried about roads being “flooded by parents” causing traffic jams along Fortune Green Road if the planning application is approved by Camden Council.

He said: “Residents are already concerned that their roads are being used as a glorified car park by users of the gym in the basement of the Sager Building.

“If the school comes in, the roads will be flooded by parents and Fortune Green Road will be in traffic chaos.”

A spokesman from Abercorn School, which currently has three separate sites in Westminster, said a plan has been discussed to provide buses to take pupils from Westminster to Fortune Green in order to reduce potential traffic congestion.

Westley Eckhardt from Sager, which owns Alfred Court, said: “Abercorn School and Sager have undertaken, prior to the application being submitted, extensive consultation with local residents and in response to feedback the transport plans were amended.

“We will continue to engage with the local community in the run-up to the planning decision and welcome further opportunities to discuss our plans with residents.”

A spokeswoman from designers PTP Architects said: “We are working very closely with London Borough of Camden and the residents. A working group has been set up to address any concerns and keep residents informed.

“With the support of the council we will continue to consult the residents.”
