Housing plans at Eastern Quarry
29 August 2012 Last updated at 21:26 BST
Plans for about 22,000 new homes in north Kent have been given the go-ahead.
The planning application was first submitted in 1996, and in 2002 was given approval.
More than £100m has been invested in the site by the developers but plans were delayed over the need for further investment and transport improvements.
The first 1,500 homes at Eastern Quarry are expected to be completed by 2020.
