Plans for a major expansion of a primary school would see it grow by nearly 100 pupils and be transformed into a “21st century” school.

In the coming years Trinity All Saints Primary School, in Church Street, Bingley, could see nine new 30-pupil classrooms, a school hall, staff car park, kitchen, playground and “wild garden” built next to the existing school as part of a five-stage construction plan.

A planning application for the project was submitted this week.

If approved, it would see the building – parts of which date back to the 1870s and are Grade II listed – more than double in size by expanding onto the neighbouring school playing fields. The school’s head said the changes were necessary to give pupils a 21st century facility.

Headteacher Jane Glendinning said: “We’ve now got four Portacabins as classrooms, so it would be wonderful to see them go. Children are getting wet and cold every time they go to the library or from class to class.”

In the next three years Bradford Council expects the number of pupils attending the school to rise by 90, but overcrowding already means 150 are taught in temporary classrooms.

The school also lacks enough cloakroom space, toilets and changing facilities for pupils – and the staff room does not fit all the staff in it.

With its expansion, All Saints could grow from its current capacity of 330 primary school pupils to 420, 270 of whom would be taught in new classrooms.

It would also lead to new jobs, with the number of staff rising from 68 to 82 and a new 45-space staff car park being built. Staff currently have to park on roads.

The planning documents reveal the school had two options – to demolish the school and build a new one in its place, or extend the existing building.

A school “vision document” prepared for the project and referred to in the application says many pupils live in poor accommodation and are “surrounded by the impact of drink and drugs”.

It says: “The new school must provide a community focus for adults and pupils who are otherwise isolated, unsupported and uneducated. It must be a hub that serves the educational, emotional and physical needs of its community by bringing together all services of support for all ages.”

The school holds coffee mornings for parents and hosts community groups, but these are also hampered by the lack of space in the building.

People have until December 7 to comment on the plans. The Council aims to make a decision before the end of the year.
