Tseung Kwan O New Town is one of the nine new towns in Hong Kong, built mainly on reclaimed land in the northern half of Junk Bay in south-eastern New Territories, after which it is named. Major residential areas within the new town include Tsui Lam, Po Lam, Hang Hau, Tseung Kwan O Town Centre, Tiu Keng Leng (also known for its English name Rennie's Mill) and Siu Chik Sha. Administratively, the new town belongs to Sai Kung District in southeastern New Territories, although it is often incorrectly regarded as part of Kowloon due to its close proximity to the city—the town is bordered by the urban township of Kwun Tong to its west.
Tseung Kwan O displays the characteristics of a commuter town as only less than 10% of the workforce living there works within the same district.
Tseung Kwan O Industrial Estate is located in the south-eastern part of the town. Apart from various manufacturing industries that could not be housed in conventional multi-storey industrial buildings, the estate is also where a number of mass media outlets locate their headquarters at, including TVB City, the headquarters of Hong Kong's largest television broadcaster, and news agencies like Apple Daily and Sing Tao Daily. The industrial estate hosts a high concentration of data centres due to the fact that three out of the eight submarine communications cables connecting to Hong Kong make their landfall at the marine frontage of the estate.
Bus routes 797M (NWFB) and 298E (KMB) connect the industrial estate to southern Tseung Kwan O. A spur line of the MTR's Tseung Kwan O line to the LOHAS Park station was completed in July 2009 and provides easy access to the industrial estate from Kowloon and Hong Kong Island. Tseung Kwan O has several major shopping complexes, all sitting atop of or in close proximity to MTR stations. The largest shopping centre in the new town now is Metro City Plaza, which boasts three phases surrounding Po Lam MTR station.
Hang Hau MTR station is surrounded by an extensive network of mid-sized shopping arcades linked by footbridges. The mainstay of this multifarious complex is East Point City. Tseung Kwan O Town Centre (Tseung Kwan O MTR station) is home to Park Central, PopCorn, and Tseung Kwan O Plaza.
There will be an iconic 480,000-square-foot MTR shopping mall The LOHAS, with the largest indoor ice rink in Hong Kong and the largest cinema in Tseung Kwan O. There will be supermarkets and alfresco dining areas in the mall too. The mall is atop the MTR LOHAS Park station.
Tseung Kwan O has a population of over 396,000 people. Tseung Kwan O also forms part of the wider Hong Kong metropolitan area which has a population of over 7,491,000 people.
