Colden School chiefs are working to secure funding for a new permanent classroom block.
Year 3 and 4 pupils are currently taught in a mobile classroom but this was damaged in recent high winds.
Following a meeting including governors and headteacher Tony Greenwood the school has pledged £70,000 to the project.
However they are reliant on Calderdale Council coming up with match funding for the project.
Mr Greenwood said: “We are looking for a decision soon as it can not drag on forever as the current temporary building is heading rapidly towards the end of its life.”
He said that the governors had worked hard and been resourceful with the school’s finances to make the £70,000 available for the scheme.
A meeting with parents will be held on February 20.
