The old Kingswood School in Corby has been demolished to make way for a new housing development.
Workers are on the site, which has planning consent for 90 homes, as well as associated roads, open space, play area and landscaping, preparing it for the homes scheme.
The work is expected to take 15 weeks and the proposed development land, in Gainsborough Road, is set to be placed on the market by Connells estate agents of Northampton.
Northamptonshire County Council was granted outline planning permission for the housing scheme earlier this year by Corby Council.
Approving the planning application, it said that the proposed housing development would not harm the character or appearance of the area and that it was in line with the borough’s plan for growth.
The school opened in 1965 as a grammar school with 150 pupils.
In 2010 staff and pupils moved to a new £26m school on a neighbouring site.
Last May, flames ripped through the empty school’s science block as 50 firefighters tackled the blaze.
The Kingswood School, with its distinctive tower block, was made famous by a BBC documentary series in 1982.
Cameramen were allowed into the school for an academic year to film pupils and staff at work.
The then headteacher, Brian Tyler, later appeared as a panellist on television’s Question Time programme and on Any Questions.
A TV film crew returned to Corby 25 years later to catch up with some of the characters from the original ground-breaking series for a one-off documentary.
