ROWLEY Hall Primary School has been given the go-ahead to provide nine new classrooms in a £2.8 million scheme.
The cash is being provided through the council's school's capital programme and the council is working in partnership with Sandwell Futures Limited.
Another 210 places will be available as it increases from a two to three form entry school to cater for an increased birth rate in the borough.
As well as the extra classrooms, a new nursery, a small hall, a studio and a new kitchen will be built at Rowley Hall School.
Cabinet member for children and families Councillor Bob Badham said: "An additional 210 places are being created as part of the council's programme to meet additional demand in the birth rate in the borough."
The new extension is to be constructed using a Super Insulated Panel system (SIPs) construction method, with completion expected for August this year.
