Dozens of pupils starting school this autumn will be taught in temporary classrooms a mile down the road because their school will not be ready in time.
Spare classrooms at George Grenville Academy will be used to teach the pupils in and buses will take them and their parents to and from the Lace Hill site.
A new opening date for the school building in Catchpin Street has not been set.
Aylesbury Vale District councillor for Buckingham south, Robin Stuchbury, is disappointed that the issues were not identified early on.
He said: “You shouldn’t be looking for gas and electrics at this stage.”
The Labour councillor believes the issues should have been picked up at an earlier stage.
There needs to be some careful analysis of how this has happened”Robin Stuchbury
He said: “There have been long-running issues and there needs to be some very careful analysis of how it has happened.
“With the growing community in the town, it’s very likely that we’ll need another school and I don’t want more to experience this type of delay.”
The Bourton Meadow Trust, which will run the new 210-place primary school, looked at several back-up plans and decided to use George Grenville Academy which it also runs.
But the two schools will run independently, which means the group of 40 will follow their own timetable and break times.
The trust’s executive teacher Martyn Kitson said he is ‘frustrated’ by the delay but met with parents to explain the situation.
He said: “The news of the delay came during one of our regular meetings with the developers and we are sorry for the inconvenience this will inevitably cause.
“Even though it will open on different premises, we are confident that every child will receive an outstanding education from day one.”
