Among the residents of Tseung Kwan O, 42% live in private housing, 34% in some form of subsidized home ownership housing (e.g. HOS courts) and 23% in public rental housing. Each of 4 more well-developed neighbourhoods in the new town, namely Po Lam, Hang Hau, Tseung Kwan O Town Centre and Tiu Keng Leng, is a combination of the above 3 types of housing clustering around a metro station. Private housing estates usually come in the form of podium-tower structures, where the podium levels are shopping malls. Most public housing estates in Tseung Kwan O are equipped with their own shopping malls as well, although mostly smaller in size than their private counterparts.
