Shropshire Council has applied for planning permission for an expansion of the building at St Laurence's Church of England Primary School in Ludlow.
The council says the alterations will create learning spaces that are more in line with current DfE recommendations.
Two cramped classrooms will be increased in size, providing safer and more suitable spaces for learning, along with a larger support space. The project will also provide an improved and safer circulation in this part of the school building.
Ludlow councillor Andy Boddington has welcomed the project: "The aim is not to provide additional school places but to improve the learning environment for current school numbers."
"Any need to increase the capacity in Ludlow’s primary schools to take on extra pupils from the new housing being built within and on the outskirts of Ludlow in the coming years will be reviewed in the autumn."
If approved, work would begin in the summer and could be completed by the end of this year.
