The NUM headquarters in Sheffield is just weeks away from a £5 million restaurant, leisure and office deal, claim developers.
Four potential occupiers are in discussions – including two up-market restaurant chains - to move into the building on Holly Street which has stood empty for 25 years.
Matthew Stephens, of Barnsley-based Brook Group, said it only needed one to sign up and a 12-month transformation scheme can start.
He said the structure has already been stripped out in readiness.
The development director said: “We are talking to two potential restaurant and leisure occupiers and two who want offices. Once we get a commitment from one of them we will be starting and hopefully it will be within the next few weeks.
“We have been working on this for 18 months. The uncertainty around the Sevenstone scheme and the state of the economy has been frustrating.
“However, there is demand and it has helped that Sheffield Council has said it will take its own Sevenstone project forward.
“There haven’t been any planning issues – the scheme was positively received and the council has been supportive. We are just trying now to get it across the line.”
The building opened in 1988 when Arthur Scargill and the NUM relocated from London to Sheffield.
The head office moved to Barnsley when the mining industry declined and Sheffield city centre was left with a prominent empty building.
