The project involves the construction of an 886,892 sq ft extension to the north-west elevation of Terminal 2 to provide extended passenger processing facilities, an extension of the upper level Terminal 2 forecourt and reconfiguration of the Terminal 2 multi-storey car park, an extension to the Terminal 2 lower level forecourt and reconfiguration of the existing forecourt, and the creation of an elevated access road to Terminal 2 from the elevated roundabout on the M56 spur.

It also features the construction of a seven-storey extension to the existing multi-storey car park to provide 2,592 additional car parking spaces and a new seven-storey car park for 4,236 vehicles.

In addition, the application involves demolishing Terminal 1 and the associated multi-storey car park, which would mean the loss of 2,006 parking spaces.

The proposed extension to Terminal 2 is part of the airport's transformational modernisation programme. Manchester Airport has estimated that the development will result in 2,000 additional workers being employed on the site.

The £1bn ten-year Manchester Airport Transformation Programme is a series of 60 enhancements that are intended to provide passengers with enhanced facilities and services.
