Galway United have submitted planning permission for a 110-acre state-of-the-art centre of excellence in Athenry.
The 'Mountain South' facility would be shared with Connacht Hockey and boast gyms, offices, canteens, a club shop, three grass pitches, five astro pitches and a soccer dome.
It would be intended to ensure the site is carbon neutral and environmentally friendly, with wind turbines and solar panels installed at the entrance.
Last month Galway United members voted to accept a proposed takeover by the billionaire Comer brothers.
The Comers - long-time sponsors of the club - moved to attempt to take an 85% share of United and the fan-owned club voted at a specially arranged meeting to allow such a move to take place. That takeover is currently being finalised.
"It puts us in a situation which the club has never been in before - to have a home of our own," a club spokesperson said on Friday.
"In time frames, I would put it at three to six months before we find out about planning permission being granted.
"This is a joint development with Connacht Hockey, which will provide for all the current and future needs to develop all young players in the west of Ireland to reach the highest levels of their sports.
The multi-purpose facility also has a full-sized GAA and or Rugby pitch which can also cater for soccer training along with two hockey fields and multi-purpose spaces for sports such as tennis and volleyball.
