The first details of a major scheme to merge an infant and junior school in Costessey have been revealed after a planning bid was lodged.

Norfolk County Council's children's services team has submitted the application to relocate Costessey Infant School's pupils onto the Costessey Junior School site, on Three Mile Lane, creating one all-through primary school.

Though the schools already work closely, sharing a headteacher and both part of the Evolution Academy Trust, the move is designed to help them work together more easily, as well as alleviating traffic with one single drop-off point.

If approved by the council's planning team, it would see a two-storey extension added to the existing building, which dates back to 1947, with seven classrooms, group rooms and a staff room included, as well as an 11 extra car parking spaces.

It would feed into the council's 'long-term ambition in Norfolk to provide all-through primary schools within local communities', online planning documents say.

In a statement on the council's planning website, chief executive of the trust Tony Hull said: 'The trust is in full agreement that the plans, as proposed, will best meet the needs of local residents, the needs of employees and the school activities.'

The plans would see new toilets built in the current staff room, with a portion of the existing junior school building demolished to make way for the new classrooms.

It has not been confirmed what will happen to the infant school building, with planning documents saying it will be 'considered for future use'.

The schools, which are both rated good by Ofsted, have about 630 pupils between them, Department for Education figures show.

A consultation on the merger was held with parents and the wider community in July, at which concerns over pressure on parking were raised.

In reports, the council said children's services would give 'further consideration' to 'pedestrian safety measures and promoting additional restrictions'.

They also said a 'travel plan' would be produced and promoted by the school.
