Connacht GAA aim to have a new indoor facility open at its Centre of Excellence outside Ballyhaunis in Mayo by the end of the year.
The facility will be an air dome which they say, at 150m x 100m, will be the largest in the world. It will also be 26m tall.
It will house a 130m x 80m GAA pitch along with a gym, running track and seating for 600 people.
The project will cost €3 million with funding of €2.1 million being provided by the Department of Rural and Community Development.
"We've had some wintry days here in this area," Connacht secretary John Prenty told RTÉ's Morning Ireland.
That was one of the main reasons we felt that we needed an indoor facility. A lot of the stuff that we do here has been delayed because of bad weather.
You could play FBD League, you could play county minor league.
Counties are getting into bother this week over going overseas on holidays, they could come to Cloonacurry and have all the facilities they'd have anywhere else.
It's a huge boost for the Connacht region and we're building it out of necessity.
Construction of the dome will begin in July.
