This bunker built in the grounds of Greystroke Hall was operational between 1954 and 1968. From 1962 this site reported in to Manchester Regional War Room in Cheadle. It existed until at least 2002 and the site was redeveloped around 2005 into residential flats, when plans included the destruction of the bunker.
The location is vague as all I have to go on is the photo from Subterranea Britannica and the gateposts for Greystroke Hall on Google Streetview below. Read about the University plans to develop the site.
