Channing School has submitted plans to Haringey Council for the building of a new sports hall and a performing arts centre, with space for a 300-strong audience.

The girls’ school, which is on The Bank in Highgate, says its current facilities are inadequate.

Channing wants to demolish the existing sports hall and replace it with two adjoining buildings. These would house a gymnasium, dance studios, an office and changing space.

The school also hopes to build a performing arts centre with a studio and auditorium space to hold an audience of up to 300 people.

If Haringey gives the school the green light, construction work will be carried out in the 2012 and 2013 summer holidays.

Roy Hill, bursar at Channing School, said: “The provision of a new sports hall and performing arts building will significantly improve the overall learning environment for students.

“This will be a high-quality, sustainable development, which seeks to preserve and enhance the character of the conservation area whilst respecting the setting of nearby listed properties.

“We will continue to liaise with our nearby neighbours to ensure they are fully informed throughout the planning process.”
