Wharf T&T Square, Demolished commercial building site in Ngau Tau Kok, Hong Kong

Wharf T&T Square was a 19-storey commercial complex at 123 Hoi Bun Road in Ngau Tau Kok, completed in 1991. It comprised two Grade A office towers, COL Tower and Telecom Tower, plus a shopping mall. It was developed by Wheelock Properties and housed the headquarters of Wharf T&T.

Wharf T&T Square was completed in 1991 at 123 Hoi Bun Road, Ngau Tau Kok, as World Trade Square, developed by Wheelock Properties. It was renamed Wharf T&T Square on 1 April 2006. The 19-storey complex housed Wharf T&T's headquarters and government offices, including an Immigration Department office from 2000 to 2014. It closed permanently in late January 2015 and was demolished from mid-February 2015 for redevelopment.

The tower's name changed from World Trade Square to Wharf T&T Square on 1 April 2006, after its main tenant, Wharf's telecoms arm. Government offices also served the public here: the Immigration Department's Kwun Tong registration office moved in from Amoy Plaza in September 2000 and left for Manulife Financial Centre in April 2014.

The building stood at 123 Hoi Bun Road on the Ngau Tau Kok waterfront, not in Tsim Sha Tsui. It was permanently closed at the end of January 2015 and demolition began in mid-February 2015, so there is nothing left to visit; the site now holds 8 Bay East, completed in 2019.

The tower was first named World Trade Square and only took the Wharf T&T name on 1 April 2006, after Wharf's telecom arm became its main tenant. It stood at 123 Hoi Bun Road on the Ngau Tau Kok waterfront, not in Tsim Sha Tsui.
