The 20,000m 2development will 'be in keeping' with the existing centre and will be linked to the £1.3 billion retail heart of the city by a glass bridge.
The extension's new shops will target the 'high-quality home market', according to a spokesperson for the centre. In addition, there will be 630 new parking spaces.
Commenting on the announcement, Mike Butterworth, managing director of the Trafford Centre, said: 'The Barton Square concept is just going to market so as yet we have not finalised any contracts although we are in advance negotiations with a handful of key potential tenants.'
'The build is due to start later this year and
the scheme is set to further reinforce the Trafford Centre as one of the leading shopping destinations in the UK.'
Completion is expected for 2007.
