The Warwick Road school’s application for a 7.4m high sports hall, with three badminton courts to double up to accommodate large assemblies and performances, and a replacement swimming pool with reception was approved last week.
Chair of the school governors, John Shaw, told planners the school’s current gymnasium was “bursting at the seams” and a new hall was desperately needed.
“The building would provide much needed capacity,” he said.
“We are sorry that local neighbours are concerned... but we don’t believe there are any valid reason for refusal.”
However the plans were unpopular with 26 letters of objection submitted along with a petition with 39 signatures on it.
Councillor Glenis Slater (Lib Dem, Elmdon) said she had a “big problem” with the hall’s impact on an already crowded parking situation as parents attended big sports or drama events.
However Coun Jeff Potts (Con, Knowle) said: “If one buys a house next to a school, they must expect children to be there twice a day and the parking that ensues.”
The plans, which include community use, were approved unanimously at planning committee on April 4.
Frank Adams, director of the nearby Nightingale Court, in Kelvedon Grove, said: “We’re disappointed to say the least.
“It was a foregone conclusion, it was almost a waste of time being here. They spent far more time on other applications. This was rubber stamped.”
