Plans to move Paisley Grammar School to a new-build community campus on the town’s Renfrew Road could cost around £72million.
The numbers have been crunched by Renfrewshire Council officers in a report that updates elected members on the progress of the project, which was given the green light in January of last year.
The facility, which will be built at the former Chivas whisky site, is due to accommodate a roll of up to 1,200 pupils and include a community café and space.
