Shopping Centre at the time) held the latter title from November 2002 until 2007 after the completion of their own expansion works. Chadstone initially held both of these titles from its original opening day to 2002 and was quickly inspired to take back the records. Chadstone's main local rivals are Westfield Doncaster to the north, Westfield Knox to the east and Westfield Southland to the south. Pre–2007 Throughout the 1990s, Chadstone had undergone numerous developments. These include the development of multi-storey carparks due to the boundaries of the centre being built-up with no further room to expand. Approximately 20% of the original mall structure is left intact with this number to be reduced due to the construction of the West Mall. By 1999 Chadstone's lettable area covered 126,000m2, after the extension of the Myer and David Jones stores. Part of stages 20 and 21, this expansion cost $150 million and took two and a half years to complete. Probuild was responsible for every major stage of expansion and redevelopment at Chadstone Shopping Centre, commencing at stage 5 in 1989, with stage 33 (West Mall) having been completed in 2009. 2007–2009 In December 2007 a A$100 million upgrade saw the centre's owners extend Chadstone's lettable area to 171,217 m2, with the centre reclaiming the title as the largest shopping centre in Australia. The new extension, dubbed "Chadstone Place", featured a Woolworths Supermarket (the first Woolworth supermarket in Victoria to have the new branding and relocated), First Choice Liquor, Aldi and a Dick Smith Electronics Concept Store along with an airport-style waiting area bus interchange, two new health clubs (Contours and Fitness First Platinum) and a crèche. On 29 October 2007 the first section of the redevelopment was open. Named "The Loop Mall", it featured 44 new stores including a redesigned Jetty Surf and new entrances opposite Kmart and Toys 'R' Us. The last major redevelopment, commencing in early 2007, impacted on almost a quarter of the centre, (the oldest section of the centre, from Sportsgirl to Mrs. Field's/Borders, being closed), from 31 May 2008, until November 2009. The development also included redesigning the roads leading into Chadstone to allow for better traffic flow into the centre. As part of the development an independent community group launched and maintained a website to keep track of construction developments.
