In 2006, after three years of design and renovation, CentralWorld was expanded to 550,000 m2 (5,900,000 sq ft) of shopping mall and 830,000 m2 (8,900,000 sq ft) of remaining complex, topping nearby rival Siam Paragon in terms of size.

[5] Anticipating the opening of the luxury Siam Paragon, CPN started massive renovations and expansion on the site in 2002.

Though work was not yet complete, CPN held an official opening of the renovated complex on 21 July 2006; it was expected to be fully operational by October 2006.

The renovated complex aimed to attract 150,000 customers per day, spending more than 7 billion baht annually.

During the evening rush hour on 10 April 2019, a fire that apparently started elsewhere spread to the eighth floor via air vent pipes, and the mall was ordered evacuated.
