A former police station will be replaced with 99 flats, including a penthouse apartment.
The Windmill Street facility became obsolete when the £30 million North Kent headquarters opened in 2008.
It shut in 2009 and was eventually demolished in 2016 following the approval of an application by Kent and Sussex Properties (KSP) to build 86 flats.
KSP then applied to up that number to 96 and the site was then sold to Elizaveta UK Property which applied to increase that figure to 99 in December 2016.
At a meeting of Gravesham council's planning regulatory board councillors unanimously voted to grant Elizaveta approval to build 41 one-bedroom, 50 two-bedroom and eight three-bedroom flats in blocks of between four and six storeys plus a penthouse apartment at the top of a seven-storey block.
Plans also include 816.5 sq m of commercial floorspace and a basement car park with 86 spaces, five motorcycle bays and room for 90 bikes.
There will be an additional six spaces, a delivery bay and 22 bike spaces on Wrotham Road.
Traffic will access the site from the Woodville Place section of the one-way system. Kent County Council Highways raised no objection to this.
While the application includes more flats, the commercial element is slightly smaller and there are less underground spaces.
It is not known when work on the site will start.
