Seven companies are set to move into offices at Park Hill in Sheffield in a strong sign of a resurgent local economy.
About 150 new people could be working in the listed concrete complex by the beginning of June if the deals - worth about £2m - all go through.
Tim Bottrill, of commercial agents Fernie Greaves, said at least five firms were buying space, a sign that confidence was returning and banks were lending again.
The investments are all private sector money and the majority were creative and tech firms , he added.
“I’m over the moon. I think these deals prove there’s life in the economy in Sheffield, particularly in the creative and digital space.
“Park Hill is part of the city’s history, the largest listed building in Europe and a superb place to live or work.
“Bearing in mind it is still very ‘Marmite’ for many in the city, when we actually take people there 90 per cent like it.
“These are they types of schemes we want to be involved in - the ones changing the face of Sheffield.”
Names will be released after contracts are exchanged, hopefully at the end of this month, he added.
Three ‘flanks’ of Park Hill have been converted by regeneration firm Urban Splash.
Some 76 new apartments were sold more than a year ago. At the same time, a total of 30,000sq ft of office space was created in the lower floors. Two creative agencies, Uber and Human, moved in early on.
The new deals would leave room for a maximum of just four more firms, Tim added.
Fernie Greaves has worked on the project since it opened a new office in the city centre in August.
Some of the new occupiers had been looking for space for a long time, while others were totally new.
Office fit outs are set to take place in April and May with the new occupiers moving in from June.
“We want to minimise the disruption to existing occupiers down there.”
The second residential phase, in Flanks ‘B’ and ‘C’, will create a further 170 apartments.
Work is set to start later this year.
