The Manx Lottery Trust has awarded a £33,000 grant to the Tommy Clucas Memorial Fund.
The funds will be put towards the 'Tommy Clucas' Community Sports Hall, which was built in 2013 in memory of the sporting hero.
Since opening, the hall - in Peel Football Club - has facilitated a variety of activities including bowls, golf, tennis, football, rugby, hockey, athletics, netball and cricket.
With the support of the grant, the new community rooms which are being developed will include the installation of a new, more accessible staircase, a passenger lift with wheelchair and pram access, and a first-floor disabled toilet.
