The former Burberry factory in the Rhondda has been sold to property developers who plan to spend up to £2.5m on the plant, it has emerged.
Burberry closed the factory saying it was not 'commercially viable'
The factory closed in March with more than 300 job losses after a campaign featuring celebrities to keep it open.
The Treorchy site will be divided into smaller units which will then be put up for sale or lease next year.
A proposed workers' co-operative to produce clothing at the Treorchy plant has also collapsed.
The purchase of the factory by the Cardiff-based property-development firm Garrison Barclay was completed during the summer.
The 106,000 sq ft (9,850 sq m) factory on 4.5 acres (1.8 hectares) will be split into 10-15 units and made available to all types of occupiers.
A number of celebrities backed the campaign to keep the site open
Managing director Tristan Hobbs said: "The local workforce in Treorchy I think offers a great opportunity for any business looking to locate here.
"The road infrastructure is good. The employment base is good. The accessibility to this building is good.
"The only disadvantage that this building has in its current form is that it is too big.
"I think that the opportunities would be fewer for the building as it stands without an investor coming in, like ourselves, and spending the money here and making it available for wider range of businesses."
Wayne Phillips, who worked at the plant for 36 years, said he hoped the development worked out.
He said: "The people who worked here are a good workforce, and everybody knows that.
"I don't know how many have got jobs at the moment but I'm sure that if there were jobs going here, they would jump at them."
The workers' campaign included protests at Burberry's London stores
The GMB union has welcomed the plan, saying it offers the potential to create jobs.
A workers' co-operative proposed at the site has collapsed because a number of senior staff pulled out. The co-operative would have employed about 50 people.
Burberry made its announcement almost a year ago that it was to close its factory in the Rhondda and move production of its polo shirts to China.
Months of protests around the world followed, attracting support from a number of celebrities.
Burberry agreed to offer enhanced redundancy payments, extra funds for retraining and to give £150,000 every year for the next 10 years to the community.
That money will be given to an independent committee.
In March, workers made a final march from the factory, which closed after 60 years of production, and were joined by a male choir on their final rally in the town.
