An application has been lodged with planners for the demolition of the former NHS Keresforth Centre on Keresforth Close, off Broadway.
Eight disused buildings are spread across the 4.2-hectare site, which is expected to house Trinity Academy St Edward’s in two years’ time.
A temporary facility, initially meant to be on the same site as the finished school, this week opened in Eastgate House - formerly a Barnsley College building.
The application said works are expected to commence by the end of this month, if the scheme is given the green light.
