A housing estate is a group of homes and other buildings built together as a single development. The exact form may vary from country to country. Accordingly, a housing estate is usually built by a single contractor, with only a few styles of house or building design, so they tend to be uniform in appearance. Generally housing estates are monotenure.

Private housing estate is a term used in Hong Kong for private mass housing – a housing estate developed by a private developer, as opposed to a public housing estate built by the Hong Kong Housing Authority or the Hong Kong Housing Society. It usually is characterised with a cluster of high-rise buildings, with its own market or shopping mall. Mei Foo Sun Chuen, built by Mobil, is the earliest (1965) and largest by number of blocks (99).
