Renfrewshire Council could have to find as much as £45 million for a second primary school in Dargavel Village after botched calculations left the initial building facing capacity concerns.
The eye-watering figure has been released as part of a report confirming education chiefs are now planning for a facility with space for 800 pupils at the housing development – not around 700 as was indicated just months ago.
Talks between the local authority and BAE Systems, the landowner, are still ongoing in a bid to identify a specific location for the newbuild.
