The part-complete Birmingham Mint development has been sold to Raybone Developments (Mint) Limited.
Plans for the £30m transformation of the Birmingham city centre site include 192 flats, together with 51,000 sq ft of commercial space.
Redevelopment of the historic building ground to a halt in January 2009 after its financial backer, the Bank of Scotland, refused to bankroll the project.
The building was formerly the world’s largest privately-owned mint.
Deloitte was appointed administrator to the Junared Group of companies, included the Birmingham Mint, in June 2009.
Matt Cowlishaw, joint administrator at Deloitte, said: “I am delighted that, with the help of many of the professionals and contractors involved with this development, a sale has been achieved.
“Work had ceased on the development in September 2007 and the sale will result in the development, on an important site in the city centre, being completed.”
David Raybone of Raybone Developments, said: “The company is delighted with the acquisition of such a high profile site in the Jewellery Quarter.
“The 192 apartments will be retained by the company and let out to professional clients as a gated community, with an onsite management and maintenance team.
“The planning will be increased to 224 apartments and 66,000 square foot of grade A office space, with 234 underground parking spaces.”
Colliers CRE advised Deloitte.
