A landmark former newspaper office opened in 1970 by Prince Charles is set to be bulldozed after a demolition order was submitted to the local council.
The Yorkshire Post vacated its old premises at Wellington Street last year when the paper and its sister titles moved to Number 1 Leeds in nearby Whitehall.
The grey concrete building, viewed as a prime example of 1960s brutalist architecture, was dubbed the “bunker” by staff who worked in the huge, windowless newsroom.
The five-storey building, which contains 220,000 square feet of office space, went up for sale last year after the newspapers moved out.
Initially it was suggested that it could become a top class hotel and conference facility or alternatively transformed to create modern offices and shops.
Paul Fox of Fox Lloyd Jones, the agent handling the sale, said: “The site has attracted wide ranging interest for a multitude of uses and we are hopeful of being able to conclude a sale shortly.”
Mr Fox said the demolition application had been submitted to “protect and encourage ongoing discussions.”
The building was designed from 1968-1970 by John Madin, who was the architect of a number of significant buildings in the 1960s, including BBC Pebble Mill studios in Birmingham.
When it was opened in 1970 by Prince Charles, the building housed more than 1,300 staff, but there were only 300 left when the papers vacated the premises.
English Heritage said in February that the building would not be listed, saying that the closure of the printing works on the site had “diminished its ability to demonstrate its original function” and had thereby “impacted on the integrity of the building”.
