Reid picked up the commission for the new 43m-high tower after winning an invited competition.
The project is part of a wider infrastructure development that aims to accommodate a major increase in passenger traffic.
The form of the tower is dictated by the demands of the brief. The design expands at the top to make space for the high level of accommodation required, while splaying out at the base to house the building facilities.
Reid team leader Peter Farmer said the design form was particularly interesting. 'To harmonise the relatively large elements at the top and bottom of the tower, compared to the relatively narrow stem, and to protect the plant, staircase and service risers, a net of stainless steel tension wires is proposed.
'Each strand of mesh is straight but the effect of the full pattern is to create a curved profile to the tower of perfect geometry,' he added.
