The college, which opened in 2014, caters for 14-19 year-olds, but has struggled to persuade 14-year-olds to switch their education there.
From next year, it will be known as Greenwich Trust School, with 150 places available in each of years 7-9 from September. For the council, it’s a quick and simple way of easing huge pressure on school places across the borough.
The expansion has already been agreed by the government, and most of the £13.7 million costs are being met by Greenwich Council. £200,000 is coming in section 106 payments from two housing developments in Abbey Wood.
Greenwich Trust School will be the first secondary school in Charlton since St Austin’s boys school on Highcombe closed in the late 1980s, eventually becoming part of St Matthew Academy in Blackheath.
The former Charlton Secondary School for Boys, which was merged into John Roan School in the early 1980s, had its upper school in the current Windrush Primary School building, next door to Greenwich Trust School.
Earlier this month, St Mary Magdalene Church of England school opened a temporary site in the old Blackheath Bluecoat building on Old Dover Road, ahead of moving to a new secondary school on the Greenwich Peninsula in 2018.
