Plans to extend Torphichen Primary School have been approved and the £1 million development is expected to be completed next spring.
West Lothian Council gave the green light to proposals at the education executive meeting on Tuesday.
An expansion will allow for an increase in pupil numbers as two additional classrooms are set to be developed as part of the plans.
The project is expected to cost £1million and will be completed by April 2017.
The school capacity at Torphichen Primary School is expected to increase in the future and council officers have recently undertaken a feasibility study to consider both the capacity of the school and to identify opportunities to extend the current building.
Executive councillor for education Lawrence Fitzpatrick said: “This significant investment will help to ensure that the school can accommodate more pupils in future and will also ensure that pupils benefit from an improved school building.
“West Lothian has one of the best school estates in Scotland and the council are continually investing in our schools to improve the learning environment for pupils across the county.”
Plans will be determined after a building survey has taken place, but they are expected to include “improvements to the general fabric of the school buildings, mechanical and electrical installations and general decoration”.
The council will also look at the feasibility of improving current dining facilities at the school, as part of the project.
