Brownfield land is currently, or was previously, land built on and therefore is prioritised for development.
Impact on planning decisions
Building on brownfield land helps protect the countryside by reducing the pressure to build on greenfield sites or land that has never been built on. It can also make use of infrastructure from existing development. Planners will usually look more favourably on development proposed for brownfield land.
Responsible organisations and guidance
Local planning authorities designate brownfield land. They also keep up-to-date registers of brownfield land appropriate for development.
