HM Prison Oakwood, is a Category C prison in the village of Featherstone, Wolverhampton, in Staffordshire, England. First opened in April 2012, the prison is operated by G4S and was aimed to be in full operation by autumn 2012. Originally called Featherstone 2, and designed to be a titan prison, it was downsized to hold up to 1,605 prisoners with construction starting in August 2009 and built in a modular fashion, the first time this had been done in the UK. Following the announcement that it would be contracted out to a private company along with HMP Birmingham, the Prison Officers Association threatened industrial action.
