The Irish Football Association has formally submitted a planning application for the proposed redevelopment of Windsor Park.
The £29.2million project, with £25.2m provided by the government, would see the national stadium expanded to an 18,000-seat capacity.
Irish FA chief executive Patrick Nelson said: "We had made it a key target to have our planning application submitted by this date and I am delighted that we have achieved this.
"The design for our redeveloped national stadium truly is impressive, and I would like to thank everyone who took the time to give their thoughts and ideas to us during the community consultation process.
"I know that the new Windsor Park will be a stadium that we will all be proud of."
If the plans are approved, the IFA and design partners RPS hope work can begin on the new stadium by next September.
