The Gaelic Athletic Association (GAA) is to provide grant aid to help the London County Board carry out a £4.2m revamp of its headquarters in Ruislip, London.

Though planning permission is yet to be granted, the GAA has given the London County Board the go-ahead by approving plans for the redevelopment.

If plans are approved the redevelopment could see the capacity of the Emerald Grounds increase to 5,000, with the ground including a 2,400-seater stand and terracing. A new playing surface may also be constructed. It is thought building could start in June 2014, with the project reaching completion in time for the Connacht SFC quarter-final in May 2015.

"The total project will cost over £4m and will result in a ground they can be proud of,” said GAA president Liam O'Neill. “The plans will be revealed when planning permission comes through but we have given it the go-ahead."

O’Neill visited London recently to discuss the project with the Infrastructure Committee. It is thought the London County Board will need to raise £500,000 initially, with the rest of the funds expected to come from the combination of a grant and loan.
