Planning permission has been lodged for a new temporary building at Kingspan Breffni Park.
The home of Cavan GAA was recently granted permission for a brand new three-storey spectator stand which will contain spectator seating, new entrances and turnstiles, as well as player and officials changing areas.
Also included are toilets, first aid rooms, media and administrative offices, a handball court, a new museum, hospitality and bar area, a sensory room, and meeting room.
As work is due to begin on the stadium, the Cavan County Board has lodged permission for a temporary building for training and workshops.
This would be located to the rear of the existing covered stand.
A decision is due on it in April.
