Clara GAA is looking to develop new changing rooms, a gym, and a spectator area.
Proposals for a former Offaly convent could see it become a 'valuable community resource' and 'focal point' within the town.
A decision on plans for St. Brigid's Convent in Clara is due this weekend.
Clara GAA is seeking ten-year planning permission to refurbish the existing building, demolish the current ball wall and rear extensions, and construct a new, two-storey extension on a phased basis.
The club is hoping to provide dressing rooms, a gym, spectator stand, ball wall and all-weather training area.
The proposals would also see the development of walking tracks and dug-outs.
Clara GAA says the former convent is used periodically for meetings and classes but many of the rooms have fallen into disrepair.
It hopes the proposed developments could be used from a number of community groups, including the Local Fire Brigade, Clara Ladies Club, and the athletics club.
A decision is due on Sunday.
