Moorside Primary School in Lancaster could expand in size by a third if new county council plans go ahead.
Lancashire County Council is consulting on a proposal to increase the school’s reception class intake from 60 to 90, to cope with an increase in demand for school places south of the river.
County Coun Matthew Tomlinson, cabinet member for children, young people and schools, has already signed off a temporary increase at Moorside for one year only.
Lynn Macdonald, Lancashire County Council’s schools planning and development manager, said: “Changes to Lancaster’s population, influenced by increasing births, migration and housing developments, has led to a need for more reception school places in that part of the city.
“It obviously makes more sense for us to accommodate expansion in existing schools if we can.”
The initial one-year expansion will be enabled by some minor modifications to the existing building at Moorside, which is based in Bowerham Road.
The permanent expansion, if approved, would need the school to be enlarged within its current site.
Anyone interested in taking part in the consultation can find it at www.lancashire.gov.uk/schoolorganisationreviews.
There is also a consultation event at the school from 3-8pm on December 5, where people can find out more and give their views.
Appointments can be arranged by ringing 01772 535103 or emailing firstname.lastname@example.org by 5pm on December 2.
