The southward enlargement will make room for a new international arrivals and departures area. In addition, the land-side façade of the old terminal building will be shifted westward over the current vehicle access bridge to make more waiting room available at the ground-floor arrival lounge and the first-floor check-in area.

A new elevated street will also be built at departures. The roof and façade will be the prolongation of the new departure hall's roof and façade, and part of the current garage will be reinforced for use as a new road and as a bus parking facility at departures.

Also included is the remodelling of the streets leading into and away from the terminal building, the northern entrance road to the apron and development of the local area.
