Glasgow says a bid by Historic Scotland to preserve a primary school due for demolition should not affect the completion dates of its pound;261 million schools rationalisation programme.
A spokeswoman for the heritage agency said: "Dowanhill primary school is a good example of a large post-1872 Education Act primary school with an imposing interior scheme, including an unusual basement level covered playground area."
But a spokeswoman for the city council insisted: "This particular design is common in Glasgow and the surrounding areas. Our preference is to demolish and build a brand new school on this site, and we will be advising Historic Scotland of our position.
"This whole process has to be about education and providing the best conditions and environment for our pupils to succeed - it is not simply about bricks and mortar."
