Demolition work is under way at Oakham Enterprise Park to remove some of the old prison buildings.
More than 10,000 tonnes of rubble will be removed from the former Ashwell Prison site once the accommodation blocks are knocked down.
Diggers moved onto the site last week to start removing the buildings, which do not form part of Rutland County Council’s business park plans.
Deputy leader of the council Terry King (Con) said: “All of the high quality workshop, storage and office units will remain but we clearly have no use for the old accommodation blocks that used to hold the prisoners in their cells.
“They were badly damaged in the riot which forced the prison to close them down so it was a fairly quick decision to demolish them.”
The council is developing a business park with a variety of office, workshop and storage spaces available to let.
One tenant has already signed a contract with the council and other businesses are in talks about leasing space at the site.
Coun King said: “It’s an exciting time at Oakham Enterprise Park and I look forward to watching it develop in the coming months and years.”
