The public's views are being sought on the proposals

The Buchanan Galleries car park would be demolised under the proposal to make way for a new shopping area.

A new car park would be built above Buchanan Bus Station, which would also be redeveloped.

A planning application will be submitted in the spring. If approved, construction could start in 2008.

Buchanan Galleries currently comprises about 600,000 sq ft of retail space and has more than 80 stores.

New jobs

Nick Davis, of joint owners Land Securities, said: "We need to improve the choice to shoppers and visitors to ensure that the city centre maintains its attraction and pull as a key retail destination in the UK.

"Our proposals aim to create an exciting, dynamic new shopping environment, attracting more visitors and bringing more wealth to the city."

A pedestrian bridge between the new car park and the extended shopping centre is also planned.

Myles White, of joint owners Henderson Global Investors, said: "The proposed development could herald a new era for the retail industry in Glasgow, not only regenerating the north side of the city centre but also creating new jobs and improving transport facilities."

Members of the public can have their say on proposals in the centre until Sunday 25 February.
