The Planning Minister has agreed to the redevelopment of Westmount Quarry in Jersey.
The former Parish Depot and disused Quarry on Westmount Road in St Helier will now be turned into homes.
Developers Dandara have been granted permission to build 196 flats, 16 sheltered apartments, a 60-bedroom nursing home and a pre-school nursery.
The plans also include ground-floor artists' studios and parking for 281 vehicles.
As part of the plans, the vehicle entrance will also be changed, improvements will be made to the access to the Jewish cemetery, and residential amenity spaces will be provided.
The developers also need to re-grade, stabilise and replant the quarry faces.
The plans were submitted to the Channel Island's planning authorities in the summer after St Helier residents voted at a parish assembly to approve the plans.
