A massive programme of redevelopment work has begun at the St Enoch Centre in the heart of Glasgow.
The redevelopment is expected to take two years to complete
Developers said the £100m project at Glasgow's St Enoch Centre shopping complex would maintain the city's reputation as a top retail destination.
The first stage of demolition work is being carried out at the former Clydesdale Bank building on the corner of Argyle Street and St Enoch Square.
The project is scheduled for completion by the end of 2009.
The new centre will have more than one million sq ft of retail and leisure space and will accommodate more than 40 new shops.
Steven Purcell, Glasgow City Council leader, said: "Glasgow is almost unrecognisable from the city that welcomed the tremendous boost that the St Enoch Centre brought some 18 years ago.
"I'm delighted that this new investment will further secure Glasgow's unprecedented regeneration as we look to a bold vision for the Clydeside adjacent to St Enoch Square.
"The corridor from the top of Buchanan Street, down to the river, is now seen as Scotland's prime retail destination and this investment maintains that reputation."
The plans include a new entrance at the corner of Argyle Street and Buchanan Street, an extensive upgrade for the surrounding St Enoch Square, a refurbishment of the existing mall and the expansion of leisure facilities with new restaurants and bars within the complex.
Claude Dion, senior vice-president of development at Ivanhoe Cambridge, the centre's owners, said: "An enormous amount of work has already been done to bring us to this stage and it's very pleasing to see our plans beginning to come to fruition.
"The city of Glasgow already enjoys an excellent profile as a 'must-see' shopping destination, but we see enormous potential in the centre and the surrounding St Enoch Square area.
Susan Nicol, general manager of the St Enoch Centre, said she was confident that the redevelopment could be a catalyst for Glasgow to "further enhance its reputation as a retail powerhouse in the UK".
