Greenfield land is undeveloped land in a city or rural area either used for agriculture or landscape design, or left to evolve naturally. These areas of land are usually agricultural or amenity properties being considered for urban development.

Greenfield land can be unfenced open fields, urban lots or restricted closed properties, kept off limits to the general public by a private or government entity.

Rather than building upon greenfield land, a developer may choose to redevelop brownfield or greyfield lands, areas that have been developed but left abandoned or underused.

Use of term in cable industry

A greenfield development is a welcome opportunity for a cable operator to choose (and install) new equipment, without having to consider any migration issues related to legacy equipment. Equipment for the local distribution hub can be chosen solely on its own merits, taking into consideration permitting, aesthetic objections, and construction costs.
