An agreement has been reached over the demolition of the former headquarters of the National Union of Mineworkers (NUM) in the centre of Sheffield.
The headquarters was built in the 1980s
The Holly Street building was built by the union in the 1980s but has been empty for many years.
Now the NUM has agreed a deal with a developer and the city council that will lead to a new office development.
Former NUM president Arthur Scargill said it would secure income for the NUM and help the city's regeneration.
"This is a good deal for the National Union of Mineworkers and the City Council," he said.
The existing structure was built when Mr Scargill decided to move the union headquarters from London.
But with the decline of mining, the union withdrew to the old Yorkshire NUM headquarters in Barnsley with the Holly Street building remaining unused.
Originally, the modern headquarters included the historic Water Works Company office fronting onto Division Street.
But this was separated off in the 1990s to become a bar.
