The multi-million-pound project is designed to transform the appearance and facilities of the station to create a mixed-use development incorporating both the current station footprint and the airspace above the station car park.
Designed to complement a wider expansion of the Buchanan Galleries shopping complex, the station concourse will be extended and redesigned to improve passenger circulation and enhance ticketing, waiting area and retail facilities.
The current 1960s front entrance will give way to a glass frontage. The Dundas Street and North Hanover Street entrances will be redesigned with new streetscapes. New entrances from Cathedral Street and the Buchanan Galleries shopping centre will be created.
Inside, the concourse will be extended, access to a new mezzanine level foodcourt will be added, and an atrium link into the extended Buchanan Galleries shopping centre will be built.
The mezzanine and foodcourt will be created in the air space above the current station car park, which will be replaced with a multi-storey facility.
Work on the project is expected to start in 2013, with completion in 2015.
