The site, described by the council as a “vacant potential development site”, is situated within Greencroft Industrial Park, Stanley and was first seen on the market in November 2024.
Part of the plot, which is located on the north-eastern boundary of the industrial park, is under offer, the authority said after a listing reappeared on RightMove at the beginning of November.
Anna Wills, Durham County Council’s interim head of corporate estate and strategic programme manager, said: “We can confirm we have listed land for sale within Greencroft Industrial Park.
“This site is allocated for employment use and would be an excellent opportunity for businesses looking for office, research or industrial space. Currently, part of the land is under offer from a prospective purchaser.
“We provide extensive support to businesses across County Durham through Business Durham. This ranges from advice and practical guidance to help with accessing funding.”
The industrial estate is located south of the village of Annfield Plain and was developed in the mid-1980s, now including a number of light industrial units.
It is predominantly occupied by local businesses, including Karbon Homes, Lanchester Wines, Allflex Livestock Intelligence, and Tosoh Quartz.
The land is largely a grassed surface with some vegetation.
A tree belt separates the site from the southern neighbouring properties.
The council says all major services are believed to be present within or near the edge of the site.
