WHITCHURCH Primary School has applied for planning permission for a new classroom.
It says it needs more space as the number of children in the village is growing.
The school needs to increase its capacity from 125 pupils to 140 within the next five years and plans to achieve this by raising its annual intake from 15 to 20.
The school wants to erect a single-storey building at its premises in Eastfield Lane using an "under-used" site next to the hall and kitchen.
The classroom would have 55 sq m of teaching space as well as toilets, cloakrooms and storage space.
It would be timber-clad with a flat roof. A covered walkway would connect it to the existing school building.
A school spokeswoman said some children living in the catchment area had been unable to attend the primary.
"The increase in pupil numbers will alleviate this situation and should enable [them] to attend," she said.
Oxfordshire County Council, the education authority, will decide whether to approve the application. Comments should be submitted by February 25.
