On 9 March 2007 Capital Shopping Centres received approval for the extension and the partial redevelopment of the existing Westgate Shopping Centre.

Enabling works, including further archaeological surveys and service diversions will be undertaken during the second half of this year and work on the main contract will start in 2008."
