Southside Wandsworth is a shopping centre in Wandsworth, London, England. When it was built it was the largest indoor shopping centre in Europe. Southside opened in 1971 as the Wandsworth Arndale Centre, and was the largest of the UK-wide chain of Arndale Centres with 110 shops. It occupies much of the town centre of Wandsworth, with five blocks of apartments, and The River Wandle running in a culvert underneath. It initially included a mix of shops, offices and restaurants, as well as a market traders hall, although the latter has since been redeveloped. At one point it also housed a large nightclub, which closed in 2002.
The centre suffered a notable decline in the 1980s and 1990s and gained a reputation as a 'value' oriented centre, before being extensively renovated and relaunched in 2004 with a significantly improved mix of shops relevant to all households in the catchment area. The shopping centre is anchored by a Waitrose supermarket, and a large branch of TK Maxx. A large recently refurbished and extended branch of Sainsbury's -is located opposite on Garratt Lane . The upper level contains 6 restaurants and a 14-screen Cineworld cinema. There is also a Virgin Active gym at the Wandsworth High Street end of the shopping centre.
With 530,000 square feet (49,000 sq m) of retail space, Southside remains one of London's largest shopping centres in terms of its ground floor square footage (aside from the Westfield Shopping centres in White City and Stratford), and currently attracts around 8.5 million visitors a year. Redevelopment of the eastern section of the centre fronting Garratt Lane is continuing, with a £40 million project underway involving the demolition of office accommodation and the creation of a further 220,000 square feet (20,000 sq m) of retail space including a new 81,880 square feet (7,607 sq m) Debenhams department store,.
