The battle of Bangkok's mega shopping malls to be the biggest and the best has a new outright and undisputed winner: the supermodern, newly launched, revamped and rebranded CentralWorld.

With 550,000 square metres of retail space and a total area size of 830,000 square metres that is 30% larger than any other shopping centre in central Bangkok, CentralWorld is now officially the largest lifestyle shopping complex in Southeast Asia

Central World Plaza
Central World is the largest shopping mall and office complex in Bangkok owned by the Central Group. In 2006, after three years of design and renovation, the expanded, 800,000-square-meter mall was opened, topping its nearby rival Siam Paragon in terms of size. The mall is the largest shopping center in SouthEast Asia and larger than Hong Kong's Ocean Terminal.

Originally called the World Trade Center, the eight-story mall was opened in 1990. The Central Group acquired the property in 2002 from the Wang Petchaboon group and soon thereafter renamed it Central World Plaza and in 2005 rechristened it CentralWorld. It is on Crown Property Bureau land. In its acquisition, the Central Group's property development arm, Central Pattana Plc, secured a new 30-year lease on the site
