An estate (or housing estate) (mostly UK) refers to a defined area of housing, usually in a common style or built during the same period.

An estate may be an expensive area to live (eg. a gated estate) or an area primarily of social housing (council estate).

A trading estate is a business area, often on the edge of a town, where a number of offices or factory units are available to let to multiple companies.

In both cases, they will have often been constructed on the former grounds of a single property which has been demolished, or on one or more fields (greenfield land) or on brownfield land.
