He said a mix of properties would be on offer including affordable homes, rental homes, and family-sized houses as well as apartments.
The 3.5-acre site will include public squares, parks and play areas so it “becomes entirely publicly accessible, reconnecting this part of Sheffield”.
“We’re going to destroy the walls, not build a wall, and let people in and through and get them to interact with it, hang out there, dwell there, work in the workspaces, have a coffee there,” Mr Heatley said.
A sports centre called Club de Padel has already opened on the site but, with construction beginning at the start of 2026, it would be “a couple of years” before the next phase opens to the public.
The main structures had been “so big and vast and derelict, and in parts dangerous”, that the company bought the site without being able to access all of it.
Mr Heatley said: “We just had to take a bit of a view, hold our nerve, and we’ll work out what we’ve bought once we’ve completed the purchase.
